Here is my wifi swith:
I opend a Everflourisch RF switch an made it empty (all electronics out).
Then I repace the electronics with a the hardware of a nokia charger (where the 5v is stepped down to 3 v), some electronics with a thyristor and an esp8266-01.
I didn’t use the software of the espeasy but wrote some code just for my need:
This way the range is way much larger, When I turn on/off the switch from Pimatic I am sure it succeded (else the switch doesn’t go to on or off) and the switch uses much less power of itself.
When I use it for turning on the gardenhose I just start the timer from Pimatic, when then Pimatic would hang, the hose still stops after the programmed time.
When there is an alarm then I can flash the lights on several ways.
