Hi JDRoberts:
I have been Googling and reading because I was also interested in trying to use the Homelink buttons in the car to turn on or off a light controlled by a GE Z-Wave switch that is integrated into my SmartThings network. It looks like you have researched more and accomplished more than anyone else working on this problem. I like your Zigbee hack of the Wayne Dalton gateway and I may proceed with that - it sounds like a fun project but within my capabilities (since you have done the heavy lifting).
I wanted to ask you if you had investigated writing a device handler for the Wayne Dalton gateway? I think the code from one of the other button devices (like the Minimote) my be hackable to get the results I am looking for. In my searching I hadn’t seen any mention of anyone tackling a device handler . . .
I can pair the Wayne Dalton with the SmartThings hub (V2) but it appears to pair as a generic Z-wave Remote device. When I look at the code for the generic Z-Wave Remote in the development environment and compare it to the device handler for something such as the Minimote, it appears to be just a shell of a device handler. I don’t see where any functions are actually coded into the handler.
I’m stuck on how you find out what codes the device sends if you can’t find it in any documentation. I think I need a way to sniff the Z-Wave protocol to see what the device is sending when, for example, I press a button.
Anyway, just curious if you went down that path - if you did and found it to be a dead end, I think I will just do your hardware hack to add the Zigbee. If you haven’t, I may take a stab at it . . .
Thanks,
Eric
