Hi all! I am "refining" some kind of LoRa connected Esp32-based Remote Controlled Relay Board with a mixed relay configuration: two Fotek SSR relay for high loads and two classical Tongling coil relay for led/neon lamps on a prebuilt breakout. At the moment (see attached relay section schema) all fo...
