My Wifi Switch (replacing the RF electronics)

---

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.

@lschip Hey, that’s nice. It is great example of up-cycling used hardware!

For those, who are not familiar with electronics and hardware modding, the Orvibo S20 smart plug may be a cheap alternative. The plug costs about 15 EUR (banggood) and works well with pimatic. There are even cheaper alternatives like Sonoff if you don’t need a plug, but you can connect to the switch using power cables.

Nive device, the Orvibo S20. I see they also have wifi doorsensors.
Thats my next project. I have an idea (stolen from the internet) to make it work on batteries with very low (almost nothing) powerusage…

Hey that’s a very nice one!
Thx for sharing!!

Another possibility is using the board from sonoff.

Wow, that Sonoffs are great alternative. I saw the software inti is crappy but you can reprogam it with espeasy software. I saw a Sonoff for $4,35 ex. sendingcosts…
