Hello,
I have a light controlled by two switches and have installed an Aquara Single Switch T1 no neutral (Single Switch Module T1 (No Neutral)) with an Aquara Move detector to turn on/off the light. The setup works perfectly but if someone use the wall switch button the whole setup fails until the button is pressed again.
I noticed that there is no more electricity where I have installed the Aquara Switch T1 device when the wall switch button at the other end is pressed.
I would like to keep the wall switch. Have you got any idea?
Vesternet have a bunch of very detailed installation guides for 2-way lighting systems, most of them are for zwave devices but the principle should be the same: Technical Guides — Vesternet (I searched for “dimmer” as I use Fibaro Dimmer 2 modules)
Unfortunately I don’t have first hand experience of doing this as all our 2-way light switches have non-standard back boxes that the modules don’t fit into 
Thanks for the guides. Looks really similar to my situation 
I will give it a try whenever I found the courage!
