Hello,
I am about to install a modified Sonoff 4CHPRO R3 but, as my electricity knowledge is basic, I wanted to share it with you to receive advice/criticism
(I will also ask questions in real life but I thought it could be interesting for some of you).
What I have today :
- Inwall push buttons
- When you push the button, it makes the contact and send 24V AC to an Impulse Switch (teleruptor ? not sure of the correct english translation)
- Then the light is either on or off
What I tried :
- Shelly1 in the electrical cabinet : Kind of work but a lot of cable and wago connectors for just one switch and the wifi reception was not always great when the cabinet was closed.
- Sonoff 4ProCH with Tasmota and SwitchMode13 on 0.1s : it works great to trigger the impulse switch as a complementary push button but I don’t know the light status(I played with esp32 and light detector to know if the lamp is on but it’s not a good solution :))
- Remove the impulse switch, replace it by Wago’s, put Zigbee lamps and replace the impulse switch by zigbee switch. Works greatof course but requires a lot work and not easy revert to former situation.Also need to be sure about the Zigbee groups to have it continue working without Deconz up.
This project :
- Sonoff 4CHPROR3 with Tasmota
- I soldered extension cable to the 4 physical button
- Replace 4 impulse switches by one Sonoff in the electrical cabinet.
- I intend to bind 1 phase through Wago’s and only put the second one trhough the Sonoff’s relay.
Questions :
- I noticed that all my inwall switch have a color wire + 1 common white wire connected to the 24V AC transfo in the electrical cabinet.
- I took the risk and connected the color cable and the white to the Sonoff and it worked. But, I assume I am sending 24V to the ESP8266 pin when I press the inwall switch. Is this ok/safe ?
- Do you seen any electrical/hazard risk with what I intend to do ?
Thank you very much for any advice/criticism !
