@Nca78 Yes, I was actually thinking using DIP switch (or even more easy to read thumbwheel switch) to give a unique ID to each node! As soon as I receive the extra radio modules I ordered, I'll test that.
@Grubstake I'm afraid you're right! But it's ok to have just a few days of battery life. As I wrote, it might be often disassembled and reassembled.
Hi @neelam, welcome to the forum!
The dimmer example should work. If you want to use only the esp8266 with wifi (no nrf/rfm or other radio), you'll also need to add gateway settings from https://www.mysensors.org/build/esp8266_gateway
The choice of MOSFET can be tricky. Seems that irlz44n was discontinued so you may need to find one adapted to the voltage and current you want to handle.
In all the cases you need to get a logic MOSFET too, meaning that they are fully open usually around 1 to 3V.
Also I'm sort of confused as it seems to me that L7812CV is a Voltage regulator, not a MOSFET. So if you are actually using that in the MOSFET spot it will definitively not work.
Especially if you are handling high current or voltage I would recommend using one from a reputable source for your MOSFET, I recently switched from mouser / digikey / aliexpress to mostly use http://www.arrow.com as you get free regular shipping, event if you order a couple of components (no affiliation to them whatsoever).
I didn't think the voltage drop would make enough of a difference to notice, but i guess it does. I might have to research and look for a more efficient Mosfet.
I have already published all the documentation, on my website, GitHub and openhardware.io
For now I leave the node as finished.
