Integrate Zelio Logic SR2/SR3 smart relay with HA

I used this device for my home automation, it’s not much more than some smart relays to swicth my lights on and off, based in pulses from push-buttons. It has a serial interface, and I have written some code in the past to turn the relays on and off via the serial connection, but it wasn’t very reliable because I didn’t understand the protocol 100%. Anyone interested in this? It would suddenly make my whole installation fully HA integrated, so I’ll be spending some time on it soon.

I’m not sure if I want to connect my 3 zelio’s to my Raspberry Pi running Home Assistant, of if I need another microcontroller in between with an existing HA integration (ESP, Arduino, …)

se mi puoi mandare il file json per pilotare lo zelio con ha . grazie
