Hi all, I have just completed the first version of a garage door opener based on Hass.io, the Raspberry Pi GPIO switch component, a cheap relay module and an existing remote for the garage door. The opener is a Steel-Line SD800 with rotating codes, and I had issues trying to use the Broadlink RM Pro. This solution is inexpensive - around $5 AU for the relay module - and is able to be voice controlled using Google Assistant + IFTTT. The solution was inspired by a commercially available wifi garage door opener which, upon investigation, also uses an existing remote to send the signal, but mine doesn’t have the $90 price tag.
If anyone has any interest I’ll take photos of the setup and post the full config here, as well as pics as I refine the solution (replacing breadboard with pcb, etc). Requires some very basic soldering skills.
Hi Chris, would be very interested. Just moved to new place with this model.of door opener.
Thanks
Shane
I also have the same garage door and would love some pics and other details.
Hi, sorry for the late reply, I’ll take some photos tonight and put them up.
Hmm. I have just used a Sonoff SV for this purpose…
With the same model of door opener?
No it’s a B&D opener and it’s just wired in parallel to the push button switch at the door and a ATA rolling code module. All 3 methods just close a circuit on the opener to trigger the door, Is there something special about the SD800 that it works differently?
No just curious. The solution is the same except I have run the relay off the GPIO pins and used a remote rather than the door switch - although the door switch on mine is actually a glorified remote, it’s not hardwired to the door. My aim is to incorporate the remote into the final pcb with the relay and build an enclosure to house the lot, it’s currently breadboarded with the remote running off its own battery.
So the Sonoff SV is flashed with Tasmota and I soldered on 4 header pins 2 of which are shorted using a dupont lead and the other 2 go to the door opener and of course 12v power. I used a $3 box from Jaycar and a terminal block for the connections, flashed the Sonoff with Tasmota and prized off the 2 resistors - plenty of youtube’s showing that inc Drzzz’s.
So then I just program the sonoff to turn off after 2 seconds and configure as an entity button in HA.
I’m getting another Sonoff so I can do the exact same thing with my Alarm and I can integrate directly with Google Assistant - no IFTTT…
Anyway, simple and works for me. I can still use the normal opener, the button on the wall or ‘Hey Google Open the Garage Door’ When I get the one for my alarm, I’ll do 2 automations, one to close the door and set the alarm and the other to turn off the alarm and open the door all controllable by Google Assistant…
