Maybe i’m a noob, maybe it might help you.
My tasmotized sonoff rf bridge learned the codes (rfkey1 4) and it showed them as well. It showed them not only for the remotes but also for the app and the main control panel! I had it flashed with portisch but i was about to throw it away when i figured it out.
It learned and showed the codes fine (rfkey1 5) , but it didn’t do anything. I sort of figured this out after someone mentioned something about adding a siren and putting it in learning mode, and then sending the rfcode. It doesn’t work if you do it via the app but if you press add remote on the main control panel, then you sent the previously learned rfkey1, it will register as a new remote and you’re set.
You don’t even need to learn the other codes, after that you can just send rfcodes (#B9D672 for disarm in my case) and voila.
Now all i need to do is figure out why my tasmota sonoff rf bridge is going offline every 8 hours or so.
