you can either set the boiler type to 0x02 or add it ems_devices.h. But shouldn't make a difference as there is only one format for EMS boilers. Looking at the data I see the Boiler temperature is wrong but the rest seems ok. Does writing work, for example setting the boiler temp? Writing to the Nefit Easy is not supported as the Easy doesn't listen to EMS requests. I put some ideas in my README on how to solve this for anyone feeling adventurous. |

When I set the boiler to type 2. I get the following result: After I do I will let my friend look at the README file and see what he can do. |

best way to debug is turn on verbose logging, look for the telegrams and
then check the code to see if the values are in the right place. Its quite
straightforward and I put a lot of effort into making the code readable. If
you find anything strange feel free to put in a pull request.

After I do boiler wwtemp 40 nothing changes.
Also the thermostat stats are a little bit off. (Real temperatures are:

I will let my friend look at the README file and see what he can do.

Dear Proddy,
I'm currently working on a little bit weird setup with the EMS level shifter and the ESP 8266.
I have drawn a schematic scheme to make it clear.
Boiler: Intergas Kombi Kompakt HRE 24/18
EzC: Bosch EasyControl adapter
TS: Nefit Easy
EMS: EMS Level Shifter v0.9
ESP: ESP8266
Firmware: 1.5.2
So, in this situation the EzC transforms the OpenTherm Protocol to EMS.
The Nefit Easy works fine.
But the EMS-Bus can't detect the Boiler.
When I do a autodetect I get the following result:
I also saw the older issue with the Bosch EasyControl adapter and followed the instructions.
After that i did a info command.
There are a lot of random values.
My first thought was that the boiler isn't supported yet.
Can I write custom code for my boiler?
My code experience is very low, but a friend of my is pretty good with C/, C++ etc.
And how far is the Nefit Easy write function?
Thank you in advance!
Daan
(Sorry for the bad english)
