    Help with smart home relays หมดเขตแล้ว left

    Project Title: Troubleshooting Assistance for Thermostat Relays in Smart Home Overview: I am a beginner in smart home technology and seek assistance installing a smart relay to my boiler. I have very little knowledge for electricity, but as far as I understand, my boiler can be commanded by a 12v relay. But the smart relays I find in the market are for 240v usage. So I am afraid to fry my boilers circuit, if I use one of those. I need someone with expertise in smart home technology and electricity to guide me to the correct products and solutions. The relay must be zigbee compatible(like a Sonoff or Aqara) or it might be a Shely wifi relay (but zigbee is preferred). I will pay hourly for consultation.
