In this case, play a Text to Speech (TTS) on Sonos speaker(s). As mentioned above here is the automation in YAML format. I therefore switched to a Man-in-the-Middle attack.
I basically have zero issue with speed/performance here. Specifically, it sends Simple Service Discovery Protocol (SSDP) M-SEARCH requests to the multicast address 239.255.255.250:1900, with the queries device:InternetGatewayDevice, service:WANIPConnection, service:WANPPPConnection and upnp:rootdevice. Resume playback of whatever was originally playing. For whatever reason, you cant pick multiple items from the drop down, but you can manually type in multiple entities seperated with a comma and a space - for example: Press question mark to learn the rest of the keyboard shortcuts. I initially understood the power kit as a resistor that allowed some current to bypass a solenoid, but it is more complicated than that. What's the best part? If you need to manually configure it, ONVIF is available at port 80, with the username admin and password equal to the 6 letter Verification Code (from the back label of the doorbell). 
WARNING: Some words of caution worth repeating from the 101: Do not change the admin password, even if prompted! I also added the snapshot and restore to my automation so the state of my speakers reverse back after the chime played. Finally, I mounted it on the inside of my electrical consumer unit cabinet. There was too much current going through the relay coil from the normal operation of the doorbell. Cloud say provides more natural sound. Restore a previously taken snapshot of one or more speakers. That leaves one or two RTSP streams (depending on the TV) left over for answering the door via the mobile app. Some things you might want to do with the Batch Configuration tool: The desktop applications will not win any awards for usability, but they work (mostly). After the work above, and with the doorbell flashed with the HikVision firmware, there were three ways to integrate the doorbell into Home Assistant: RTSP, ONVIF and via the Shelly Uni push sensor. His materials are online at this dropbox link. I examined Simones pcap file in Wireshark. Using the PC (that you have installed Batch Config Tool on), connect to the WiFi access point of the doorbell (with an SSID like softap_
Therefore, the doorbell must send caller-side audio both through UDP video stream and through the TCP voice server; meanwhile audio from the app is sent back to the doorbell only through the TCP voice server. This is an apparent attempt to discover the WAN IP address over UPnP.
But integrations and 3rd party code can give you details like "Is the Living Room dark" or "is there motion in the driveway." Pick one speaker to serve as the Master, and then specify the rest of your speakers. UPDATE: Thanks to Reddit users u/Eriner_ and u/pie_faced_avitar for both suggesting to use the sonos.shapshot and sonos.restore services to pause and resume whatever may be playing when the doorbell chime is played. Another problem is that since a smart doorbell is continuously powered, the normal current in the circuit might be enough to trigger the Shelly. You need to tell Home Assistant to wait for the announcement sound to finish by creating a Delay action. It works! Install File Editor by following these instructions. Sonos addition was the simplest integration installation. I have left it at 12V ever since. I once needed to start over at this point after changing the doorbell WiFi to one that didnt exist. I would have loved this guide when I figured it out as well. You can see the relay closing at the same time that the multimeter measures a drop in voltage across the doorbell as the doorbell closes the circuit (note: I was powering the doorbell with 24V AC during this test). I also see that my attempt to connect the doorbell directly to the Unis IN_1 was misguided, because it meant that the Unis IN_1 and N were short-circuited and could have not a voltage difference for the Shelly to detect. Clear the sleep timer on a speaker, if one is set. Consider leaving a comment below or sending an email at johnzanussi@gmail.com. Use of the Shelly Uni to detect dumb doorbell presses is discussed in forums here and here. Its a little unintuitive, but you must have both Receive Call from Doorbell and Notifications turned on. Excluding litedev.ezvizlife.com, none of the other IP addresses were discovered using DNS. You'll find that any internally connected device you have likely has an Integration available. Please upgrade! Once I made the decision to upgrade I went all in on Ubiquiti's UniFi line of products for both networking and video security replacing all the networking and Ring devices in the house. Because there is no dependency on cloud services for its core operation, the device is safe from planned obsolescence or having its servers turned off. As soon as you approve that notification, you should have access to the doorbell from both apps (and you can uninstall Hik-Connect at this point if you like). What would an open source smart doorbell look like? Play with colour profile, white balance and so on to suit the doorbells location, Flash the doorbell firmware (e.g., to a version that supports ONVIF or removes the ugly EZVIZ logo), 3 Amazon EC2 hosts in the EU-West region (Ireland). It is true that it uploads camera snapshots and audio (and sometimes video) to servers, but no more than any other smart doorbell. I used the audio file linked in the post (converted from wam to mp3). Using Ohms law, R = VI = 11.6V/0.2375A = 49. I posted this on Reddits /r/homeassistant, and a commenter suggested posting a snapshot of the revlevant part of the automations.yaml file. That requires one of the apps, and the peer-to-peer connectivity they implement. Alternatively, there are some manual configuration options, listed as follows: To add your Sonos components to your installation, add the following to your configuration.yaml file. In these threads, the Shelly is powered by the same source as the doorbell chime transformer, but it is detecting a dumb doorbell (basically a momentary switch), not a smart doorbell. You'll need a single "Trigger" which is activated when the doorbell button is pressed. Home Assistant with UniFi Protect Integration, How to add Sonos Integration on Home Assistant on Home Assistant, How to make an automation that allows Unifi Doorbell push to trigger Sonos TTS announcement. In any case, I decided while writing this post to take a close look at who this device tries to talk to. If you do not intend on using Frigate, I suggest you consider installing the RTS2P addon (Settings > Add-ons > Add-on Store > overflow menu > Repositories > Add, paste in https://github.com/snowzach/hassio-addons, click ADD, and then select and install RTS2P). You can test that it works by loading it up into your browser. Newhouse Hardware CHM1 Door Bell Chime, White, Doorbell Transformer Compatible with Ring Video Doorbell Pro 16v 30va Hardwired Door Chime Transformer, Honeywell Home Wired to Wireless Doorbell Adapter Converter for Series 3, 5, 9 Honeywell Home Door Bells - RPWL4045A, White, Honeywell Home RDWL917AX2000/E Doorbell Portable Wireless Doorbell & Push Button-9 Series, Blue, Play chime on Sonos when doorbell is pressed, 8123/local/sounds_sounds_ring_button_Chime.mp3, No sound being played when the doorbell button is pressed, A very long delay between the doorbell button being pressed and the sound being played, The sound being played on repeat at random times during the day (and middle of the night) without the doorbell button being pressed. Does this work even when the internet is down? I preferred a solution that could be powered by the 12-24V AC power supply that was already in place (admittedly, I could have added a rectifier and resistors to convert to 5V DC at the cost of added complexity). I therefore think that the IP addresses used are configured dynamically when the doorbell phones home to litedev.ezvizlife.com:8666 at startup. Connect the other end of the doorbell circuit to the switching input of the smart relay. Heres what I hear when the mail gets delivered: (I turned this off after a few days, but you get the idea ). One of which is setup as 5.1 system so it did not separate surround speakers or bass but rather showed up as a single speaker entity. Here are those instructions with accompanying screenshots. Install a smart relay and a DC power supply. no uploading of snapshots to Amazon S3 or any other internet service. This basically tells the doorbell to initiate a connection out to a peer that is seeking to connect (e.g. Now, go to Configuration, Automation, and Add a new Automation. These apps are very similar, and some of them seem to even share the same account backend. Connect the AC transformer and chime (if any) to the outputs of the relay. You can read this post linearly, or jump to the bit youre most interested in: This devices biggest flaw is that button presses are not exposed via any API. I suspect that it might be a software library containing eCos RTOS and/or IOTO. The folks at IPCamTalk discussed this and found the Guarding Vision app the be one that works reliably (corroborated by reviews on the Nelly Security site). If you are on a different network than your device, but it is still routable (e.g., you can ping it), then you can use the +Add button in the toolbar to directly add it by IP address to the top area. I had done most of my testing on 24V AC, but found that I could switch the transformer over to 12V AC and everything continued to work fine. Based on this, I think I can confidently classify the various services the doorbell talks to as follows. Once everything was working smoothly, I experimented with voltage. If that works, you know you can automate Alexa and make it say things. I notice that the RCA Security app allows you to use the intercom separately to the video feed.
It surprised me that a TCP server is used to relay voice communication. A few different entities will be available over ONVIF: A doorbell snapshot image is available at the URL http://DOORBELL_IP_ADDRESS/onvif/snapshot.jpg, if you want to include it in mobile notifications etc.
The DB1 has higher specs than the Nest or Ring, but a more open design. This would have the lowest possible latency, and eliminate a server dependency. I've interviewed the creator of Home Assistant on my podcast and I encourage you to check out that chat. These values are expected by the mobile apps. Like any IoT device, it could contain a hidden backdoor that could activate sleeper code that does something I didnt observe in my tests, but the same caveat goes for nearly every bit of software running in all our homes. no separate voice relay server. I have done my best to analyse all the other traffic generated by the doorbell, by poring through Wireshark captures, doing an interactive timing analysis by playing with the doorbell features while monitoring its traffic, and by blocking services to see what would happen.
Boolean that defines if the alarm also plays on grouped players.
In the packet captures I studied, I could see the doorbell simultaneously connecting to services at different IPs and ports, probably to increase the chance of success. The doorbell plays through two sonos systems, but you'll be able to remove one of them/change it however you see fit. This will apply for sharing, and will send a notification to Guarding Vision. Contains all features of free version and many new additional features. If youre running Home Assistant in Docker, the www folder should be in the root of your Home Assistant Docker volume. Ideally, like a traditional doorbell, we'd hear some audible notification in the house. The file B0100.lzo was uncompressed successfully and seems to be compiled object code, which still contains debug symbols and various other interesting strings (even file paths on the developers computers). There is already a peer-to-peer connection to the app that snapshots can be downloaded through. After a few days of running new ethernet drops, installing equipment, and getting things configured I was left with a setup I was happy with but there was one issue. Monitor the doorbell wire to detect current being sent to the chime. A screenshot of the entire automation config page is also available. Here are some comparison screenshots between the various apps. Found the above useful?
To perform the share, start in Guarding Vision, click the sharing icon on the device, Share with User, then Share via QR Code. The Guarding Vision and RCA Security apps therefore complement each other well: Recommendation: Install both apps. Unfortunately the EZVIZ app has a prominent ad for cloud storage plastered on nearly every screen, which you cant get rid of, and which I couldnt bear to look at. In my case, that would be media_player.kitchen_sonos, media_player.bedroom_sonos. Its worth mentioning that the call quality in all these apps far surpassed my experience with Ring Pro or the Nest Wired doorbells. I havent tested this hypothesis, but Id be fascinated to hear other peoples opinions on it. Integer number of seconds that the speaker should wait until it starts tapering. This is a good chance to see if the global volume you set previously is too loud/quiet. When you stream that camera entity, you are streaming from the Frigate proxy, not directly from the doorbell. 
This basically involved removing AC from the relays output contacts and replacing it with a 1.5V battery. Although some configuration options are available via mobile apps, advanced configuration is possible by using a desktop app. Once done, it is not reversible and cannot be Reset either by Factory Settings Reset or Firmware Reload. So in the end you will have one action entry per speaker as following. By default it supports auto-discovery provided by Home Assistant, and you dont need to add anything to your configuration.yaml. Cache will basically access the cloud for the first time and reminder will be locally processed so it becomes really fast after the first ring. I decided to find a different route. The IP addresses I observed were all located in either Amazons AWS datacenter in Ireland (EU-West), a Tencent datacenter in Germany, or a UCloud datacenter in the United Kingdom. If Im home, I usually have some music going over the Sonos system. If you want to create the automation in code I've included automation in YAML format below. Should be also restore the group state of the speaker. I now believe his doorbell simply reacted to these firewall rules by failing over to using alternative endpoints.
Home Assistant will probably auto discover the doorbell. To update the firmware, I followed the instructions given by @alexdelprete on the IPCamTalk forums. Recommendation: For peace of mind, isolate the device on a VLAN or a separate WiFi. I believe setting up Home Assistant on a Pi is the best and easiest way to get started. The DB1 Pro, DB1C, DB2, and DB2 Pro are completely different devices. You can also create a XSPF file on your desktop to act as a VLC shortcut for quickly opening the doorbell stream from your workstation. Here's a quick video my wife and I recorded to showcase how responsive the automation is. I am experienced with low level networking and peer-to-peer systems. The suggested diagram is very close to one of the configurations documented in the Shelly Uni user manual for AC buttons and switches: I did my best to turn this diagram and the tips in the above forum posts into an implementation for a smart doorbell, but I didnt find a way. Nearly all the endpoints were different in each test run. Not yours. The relay might close spontaneously, or would not open after the doorbell button was released. Recommendation: For peace of mind, isolate the doorbell onto a separate network from cameras and UPnP devices in your home that it might access via multicast, and which might contain sensitive information. To get this working you have to wire your doorbell's power wires into the Doorbell Adapter then wirelessly link the adapter to the chime speaker. Cheers!
Should be also snapshot the group state of the speaker. Note that your Entity names may be different if you give your front doorbell camera a different name.
