I want to replace the existing (toggle) with a touch one.
That one is not bad, I think, but if I put a touch one it’s not possible, argh, or else I put this module in the box and I put a ZigBee mechanical remote control.
Attention, for the two-way switches, it’s not simple… Personally, I haven’t found a solution that doesn’t require a complete overhaul of the installation other than putting simple wall-mounted battery buttons interfaced via Gladys to a relay like the Sonoff Basic R2…
The problem is that you need to connect both ends of your two-way switch to the terminals of the micro-module in addition to your phase, and generally, since everything is in series, this is not possible…
