Sonoff Basic Decora Cover (Capacitive Touch Version)

thingiverse

This is my remix of the cover for masson's sonoff enclosure (https://www.thingiverse.com/thing:2804973). I've modified it to house an httm capacitive touch switch (https://www.aliexpress.com/item/5-pcs-Blue-Color-HTTM-Series-Capacitive-Touch-Switch-Button-Module-New/32471771544.html). A power icon has been inset so that it glows when the sonoff is turned off to be easily found. The touch switch is wired into GPIO14, and the input is connected to ground using a 10K resistor. For this particular switch I'm using Tasmota firmware and GPIO14 set to Switch4 - Switchmode 4. A YouTube video of the switch in action can be seen here: https://youtu.be/Nk1kS23YD8s Note that these capacitive touch switches come in latching mode, which is what I'm currently utilizing them for. You can solder a resistor to convert it to a momentary switch, I think I'll end up going this route so the LED remains constantly on. The drawback of having the latching switch is that if you turn the switch off remotely, the LED on the switch will stay in an off state and I don't believe there's a way to change the design. Changing it to a momentary switch will ensure the LED stays on so it can be seen in the dark when turned off remotely. Update: After soldering a resistor to one of the httm switches to give the momentary mode a try, unfortunately the switch defaults to an OFF state and goes high with the LED ON while touching, this won't work for me. Keeping them in latching mode for now.
