Hello Everyone,

Does anyone know which would be the best RF Bridge for Sunricher AC Phase Cut RF + Push Dimmer? It uses 868/869.5/916.5/434MHz radio frequencies.
That is similar to my remote control: https://www.sunricher.com/media/resources/manual/SR-2833k5%20instruction.pdf

Thank you!

Searching the web, I can’t find anything controlling these frequencies. I will probably need to solder wires to the remote’s buttons and wire them to a DO module. The question is, which module can hold the state until it’s released? I need 12 otputs.
