Would changing the sensitivity help any? Right now i can get it to turn on with my finger about 6mm off of the board . Theres only one capacitor that comes on the board which i probed to be a 90nf ceramic cap and its the C1 cap as per datasheet between VCC and GND . The board does not come with a ca...

btw what touch sensors did you order . I have tried both the red ttp223 and the blue ttp223 boards . The blue i couldnt get to work correctly even on the breadboard .The only way i could get it to turn on is by directly putting my finger on the TTP223 chip itself.

The Sonoff basic uses both: A switching power supply from mains down to 5V and a linear regulator from 5V to 3.3V The transformer might produce some EMI as paxi said. This may influence the leads and the touch sensor itself. I never tested the power suppy of the sonoff for noise or connected extern...

I had similar issues with a PIR module in a sonoff, it depends on where the wires run in the housing. I think it's stray EMI from the transformer - a 100nF cap between ground and signal should fix your problem, I just re-routed my wires. ;) I just added a 100nf cap but its still doing the same thing

Looking at the sonoff its using a AMS1117 3.3v regulator and i probed a 15uf cap off the output pin

Its a Sonoff .Its has built in AC supply and esp8266 on one board. Very popular and common product. https://www.itead.cc/smart-home/sonoff-wifi-wireless-switch.html It is not the wifi signal i dont think because i can pretty much put the touch switch on top of the esp antenna and it works fine on th...

I made a touch wall switch using Sonoff basic and TTP223 (red) touch module on GPIO14 .I used ESPeasy and it also is controlled through openhab via Mqtt . Everything works perfect on the breadboard (connected to pc with ftdi) . My problem . When i intall it with AC power i have a problem with the ma...
