If you want to blow your mind then you can use the Athom developer tools to record a signal and then other third-party software to analyse it and eventually create an app to listen for them. But, be prepared to invest a lot of time on it. Basically, different controls will employ either Frequency Modulation or Amplitude Modulation to add their data to the base frequency and that will be a series of 1’s and 0’s that encode the commands, etc, so that all needs to be worked out. Then it needs to be translated into Homeys way of working so that the received signal can be decoded by the app. If you are talking about RTS, there is also a small issue that it is on a slightly different frequency to the one that Homey listens on (it’s been too long for me to remember the exact frequencies). When Homey sends an RTS signal it first changes the frequency, then sends the data, before putting it back to it’s default. It was great for the old LightWave RF devices as it listened on the same frequency as those, so their dimmers and switch worked with Homey.
So, to sum-up, you need a specific app for each device, and if that is not in the store then you need to be a good engineer to make your own.
