Arduino library and hardware shield to send and receive data from Opentherm devices
Hello, I use the shield with wemos d1 r1. Shield uses pins D2, D3, D4 and D5, which is mapped to gpio 16, 5, 4, 14 according to 
Hi, Thanks for this project! It runs very smooth! Only one thing I noticed is that I can't use OTA updates when including this library. The problem is in the...
Opentherm smartpower allows thermostats to ask more power from the slave. This is not in the code yet. It uses same schematic and is only software based. In fact, it...
This pull request adds support for SAM D21 based microcontrollers. It was tested with a Sodaq Sara 412 AFF board, but it should work with an Arduino Zero as well,...
Correct me if I am wrong, because I am a digital specialist, not an analog. But I think R8 on the rev4 shield must be 25k instead of 20k. Because...
Hi, thanks for this fun project! I've just built some rev. 4 boards. And I'm testing with two WeMos D1 R2 boards and an Arduino Uno. For all boards the...
Hi, I had to changed the type conversion for negative values from the unsigned type BYTE to CHAR to allow the sign (of the float) to traverse to valueHB. void...
Thank you for the awesome project. I am quickly trying to build the pcb, however I have no bc858B nor bc848C readily available. I figured the BC858B for the master...
Hello again. Back in 2020 I never got my boiler (Remeha Quinta Solo) to work with the OpenTherm shield Rev 3 : as soon as I connected it the boiler...
hi, for pcb assebly you need an BOM and/or CPL file, does anyone know how that works and where i can get those for this shield?
