An adapter for inter Xiaomi without neutral, 2 lines. /////////////////////////////////////////////////// UPDATE : inverter///////////////////////////////////////// I use this double pole switch 2-phase without neutral for a roller shutter: I made an inverter with 2 relays 220V 8A so that even if both push buttons are activated manually or by automation, none of the two phases will be sent to the motor and especially not simultaneously! relais : https://www.ebay.fr/itm/Rel%C3%A8-relay-230V-220V-8A-circuito-stampato-pcb-2-contatti-c-o-in-scambio-RT424730/221884524443?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m2749.l2649 With this security, even if both Xiaomi push buttons are activated manually or by automation, the engine will not burn because the two phases will not reach the engine. In my automation, before controlling the rise of the shutter on the left switch, I make an automation to turn off the right switch, and vice versa, before launching an automation to control the descent of the shutter on the right switch, I make an automation for turning off the left switch. So I'm sure that my automatic rise of the shutter in the morning will be done and the automatic descent at night also because if both switches are ordered, nothing happens, purpose of the inverter. This is to overcome any accidental support during the day or if children play with it. Xiaomi has not yet planned this in their scenario. We must remember that it's primarily to manage 2 lamps lol... But a shutter consumes very little and these switches can handle up to 2500W total, say 1250W per switch... It leaves some margin. Mine consumes 250W maximum at startup... Make your welds well and you won't have any problem. If you're chilly, take a hole plate mounting to weld your relays and integrate them in the shutter box or junction box... I prefer having them behind the switch; it's inside and well protected! If you have any improvements to make, I'd be happy to discover them. //////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////// These inter have a square base and do not fit in our standard 60mm round pots... lol... So it puts the inter applies, but it is acceptable (for me) level final rendering. Instructions: 1-Unclip the cover of the 2 buttons of the Xiaomi switchgear. 2-Pass the 3 wires: phase arrival and 2 phases returns in the 3d print cache and connect the Xiaomi switchgear. 3- Put the apparatus in the base 3d print (the 2 ergos in the horizontal so that it coincides with the holes of the center pot embedded in your wall). 4-Fix the assembly with 2 screws to plaster of 45 or 55mm length. 5- Reclose the button cover on the switchgear.
