The circuit should use esp12e module (not any breakout board as this has to go in a PCB) 2. The Power supply used should be a 230v to 5v Hilink power supply (or anything smaller) 3. the Switches should be made of triacs (and mos3041) 2 channel (no electromechanical relays to save space ) 4. one AC dimmer using triacs. I would be providing the firmware for the same I Only need the circuit. I already have a working circuit using NODEMCU and electromechanical relays this job post is to make another circuit which is smaller in size. Thanks, Shekhar
