Hi, i am more of a programmer but i want to try some ‘making’ … so please be patient. I don’t know too much about electronics.
In my flat i have several T5 fluorescent uplighters.
5 sets are switched on by a simple push button connected to Eltako S12-200 teleruptors
1 set is dimmable and operated by also a simple push button, short press: on/off, long press: dimm up/down. This is done by this Niko that outputs a 10VDC to the dimmers.
What i found about the Eltako:
The teleruptor is switched using a 24V AC pulse.
Bistable, and does not use any power when not switched.
The Niko:

(English version starts on page 55)
I have a raspberry pi nearby that electric board that runs my OpenHAB, so i could use that but i also could use a NodeMCU, as i still have some laying around and i know how to connect those with MQTT. (Have a few with temp, light and motion sensors)
Now for the Teleruptors i am thinking about putting something in parallel over those inputs, that can simulate the pulse so i can ‘switch’. I know i will need another way to keep track of the state. (For example a light sensor nearby the light itself) Or should i measure that output 230V AC ?
Also for the Niko i would need something to simulate long or short presses. There i think that if i could ‘measure’ the output 1-10V, that should give me some information about the state of those dimmable lights.
What do you guys suggest ? what would i need to simulate those buttons from a NodeMCU or raspberry PI pins ?
Hope i provided enough information …
Thanks in advance for any reply.
