Hi guys, I have this old doorbell which is the Kaku CDB-6500/C with its matching transmitter. Want to add to Homey, but looks like it is not supported. Any workarounds to add it?

Thanks!

Bart

As far as I can see that model is using older transmission codes with 16 possible values, which I think is no longer supported. If you can’t learn it as if it was a 7000 model I think you’re out of luck.
