    I have a wiring diagram for my lighting system. Hardware I am using: - 3.3v to 5v Logic Level Converter Module - NE555 DC Delay Relay (5v version) - DC to DC 12v to 5v Step Down Converter Module (5v, 3a output) - WT32-ETH01 (running WLED) - Wago Connectors - 12v Power Supply I need you to assess my wiring diagram, tell me why it's not working as intended and tell me how to rewire it. I will then follow your instructions. You're required to work with me until it is working as intended. My level of knowledge in this department is low. I can solder etc, but when it comes to understanding wiring diagrams found online, it's beyond my level of knowledge, so I need someone to not only know where I've gone wrong, but to visualise what I need to do in easy-to-u...

    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.
