MQTT relay [MQTT] "Omega2"
Plan loock like that:
Finaly I was add Temperature sensor on Onion2 and Cooler - controled by PWM works satisfactory.
(Using Dc-DC converter beuse i dont have 230V->3,3v, and 5V relay, lack 3V relay.)
Which packages did you install on your Omega? Do you have example code available?

looks like this is a plenty of electronics. where can i get started to learn to electronics lol
Sorry a side note...
For all this effort, it seems to make a better sense to buy a COTS Sonoff WiFi Relay unit for less than $8 shipped. I do value your DIY spirit. On the other hand, safety is also important thus COTS route should be considered as well.
THIS IS TOO DANGEROUS
NOT GOOD TO SHOW IT
230VAC IS A RISK FOR PEOPLE WHO SEE THIS POST.
MUST BE DELETED
SOMEONE WITH CORRECT SKILL WILL NEVER NOT DO LIKE THAT.
A NEWBIEE PROBABLY SO DANGER!
Note that this is an Advanced Project and can be dangerous if not handled and wired properly. Proceed at your own risk.
However, if the instructions are followed precisely and carefully, it is definitely doable.
