Description

Wemos HLK-PM1 power board.

I needed a wemos to control a solid state SSR-40DA relay switching 240Vac. So designed this to power the wemos and be able to supply the control signal to the relay. I am intially using a relay shield to switch the SSR-40DA relay however will be looking at changing this to an opto-isolated shield in future.

This is set up to be able to remotely control a hot water system in a holiday house.

I can turn the hotwater system on or off from any where there is an internet connection.
