Description
My Wemos D1 mini doesn't work correctly with Fotek SSR with load (lamp or boiler).
Wemos turn on only signal lamp on the Fotek SSR, doesn't turn on tha load.
Wemos output pin has 3,3 V and doesn't have current to turn on load.
BC337-40 can help to turn on the load, but control is became invert
