Hi all. I am looking for an OH-compatible garage door opener or at least status sensor (to show open/closed). Ideally it should connect to OH just using WIFI and be easy to connect with an existing binding. I have found affordable products such as this one here but I could find no bindings for them:
I have also seen here a posting about Garadget, which seems to be OH-compatible but is rather expensive. Are you aware of a cheaper compatible solution? Thanks
there are quite a few that are supported by zigbee2mqtt:
https://www.zigbee2mqtt.io/supported-devices/#e=garage_door_contact
So all of those can quite easily be controlled by openhab.
Maybe some work with just the zigbee-binding too.
Or a shelly 2PM in rollershutter mode?
If all you care about is the open/closed sensor, an ESP8266, ESP32, or RPi W2, a reed sensor and some wires will be the cheapest option over all I think. With Tasmota or ESPHome setup and configuration would be pretty simple. For the RPi I’ve a program on github that makes configuration of that pretty easy. To add the ability to control the opener, you’ll need a relay too that you can wire to the wall button. Again, configuration on an ESP or my sensorReporter program on github makes configuration relatively easy.
A garage door sensor/controller was my very first home automation project. Mine still runs on an RPi 3 (I added a camera which I’ve since removed so don’t need that much power) but I’ve it on my list of to-do to move it to an ESP8266. I even have all the parts, just not the time to do it.
I can’t speak to HAMA or LoraTap but just because it talks over WiFi doesn’t mean they can work with OH. If you don’t find anything about them mentioned in any of the add-ons it likely won’t work. But pay attention to the standards used. Some of the LoraTap devices mention Tuya which I think there is an add-on for on one of the marketplaces.
But I also know that a lot of people use and are very happy with Garadget. You probably would not go wrong with it.
FYI I just found this this solution, which works just well for me…
It depends on your garage door motor.
Most simply need a "relay contact” ie by connecting / shorting two terminals together, it simulates the garage remote / button press. In this type, you simply hook up any esp8266 / ep32 to a relay, or even just to a transistor or mosfet (without even using a relay), and you could electronically control the connection of those two input terminals.
There are some ready made stuff you can use if you don’t want to make your own.
Many years ago I started with Garadget, because it used laser to detect the open state, but eventually I made my own to have these features:
To achieve it, I use an ultrasonic distance sensor to detect how much the door has retracted, and also use a laser ToF sensor (vl53l1x) to detect the trunk opening. I use an esp8266 + esphome to do this.
Another popular thing you can look at is ratgdo they have a commercial product you can order, or you can diy build it yourself.
