link to instructions for connecting to ebus? #27

Hi, this firmware looks great! Please is it possible to include links to instructions how to wire NodeMCU (and the other module types) ? Just to complete the picture..

I have the firmware loaded on my nodemcu but I don't know how to wire it to my heater. I understand it's possible to make a simple read-only ebus interface with these instructions:https://ebus-wiki.org/lib/exe/fetch.php/ebus/arduinoebus.pdf Is it possible to use this with it?

Thank you Tom

you can basically link it in several ways as the pins to be used are configurable to a certain extent. usually the RX+TX pins are used. wrt the interface you mentioned, I don't know if this works. just try.

I agree with @perfectom I also think this would make this (for me potentially) very useful repository even more useful. @john30 would you be open to pull requests that would add this information to README.md for example?

Hello John30,

so https://easyeda.com/slavikb/EBus_Controller-26362750260a4f6baa63b59b5b35698d should work then as an interface, if we leave the LEDs away?

Regards, Edi

I guess this should work, but you need to try

Hello. Maybe this is not actual, but this schematic is working, I repeated this adapter.

may be, but it is a very old design that consumes too much power from the eBUS. We have a brand new design now doing that a lot better
