I've installed my new Ezviz DB1 last weekend and I'm really happy with my setup. I had a Ring 1 before, but without the subscription (I don't want to pay 30€ per year only for recording). I'm running openHAB with many different devices and thought it would be really cool to integrate the camera too. My Ring Doorbell was also integrated, but only via ifttt. I've configered the doorbell button to send a signal to openhab via ifttt to trigger my chime (Google Home speakers). There is also a hue bulb at the frontdoor which were triggered by the motion detection inside my Ring (also via ifttt). This setup was sometimes very slow and for sure...it doesn't work without internet.
The Ezviz DB1 worked very well out of the box (fast, stable, good image), but also doesn't have any open interface for the doorbell button or motion detection. Thanks to you guys here! I've found my perfect solution:
First of all i've flashed the hikvision firmware to get ONVIF support. That makes it possible for me to 1.) get motion detection working with onvif2mqtt, 2.) add the camera easily to my synology surveillance station, 3.) get a live jpg snapshot to view on my openHAB UI. The next thing was the doorbell button. I've seen many different solutions in this thread, but most were not possible in germany. I couldn't find the devices (with shipping to germany) or the shipping fee was very high. But i've found a Homematic doorbell sensor (
HM-Sen-DB-PCB) which is working with 2 x AAA batteries for 5 years and costs about 25€ for a building kit. You have to solder some parts, but nothing difficult. This device needs a Homematic bridge, which I already own because my heater thermostats are also from homematic. And now comes the cabeling. I could use my 28 year old 8V transformer. Two lines from the transformer came out of the wall where my chime hung before (not working since years) and two lines go from there to my doorbell. I've used the fuse, to bridge one line directly to the doorbell. I've connected the other two lines to the power pack und the power pack in parallel with the homematic module. I've used my old mechanical chime as a housing (cutted out all unnecessary parts like the magnet) so that I wasn't necessary to drill new holes and it looks like before.
My result is that I have still information about motion and doorbell rings in my openHAB system to ring my chimes (Google Home Speaker and lights) and turn the light outside on and it is much faster now then before (no more ifttt). I have live snapshots in my smart home UI and can record everything to the internal SD or to my surveillance station with pretty good quality.
Just wanted to let you guys know how I solved my problems and maybe the homematic sensor should be listed in the 101, to help others with the same problem. If you have questions, just ask
Ah...and one last thing. It would be really great if I could add my Ezviz DB1 to Google Home. It was integrated before i've flashed the hikvision firmware. After flashing i've disconnected it from Google Home to reconnect it again, but now I'm getting an error, that the settings could not be saved. Does anybody know if this is a general issue on ezviz's site at the moment or does it have to do with the hikvision firmware? Does anybody got it to work on a Ezviz with Hikvision firmware before? I've tried to find such an information in this thread, but couldn't find something useful with the search function.
