![]() ![]() The ESP32 can be programmed in various ways and one of it is ESPhome (which I favour). ![]() The original has the disadvantage, that you still need something like a Raspberry Pi, a power supply, a USB-Serial converter with (old fashioned) level shifters and all that stuff from the 1970's.This module just integrates an ESP32 and directly connects to the 5V-TTL serial interface of the Logamatic. If you have the module already assembled and want to start over, this is the right place to look at.The module is just a simple way, to replace the original KM271-RS232-Extension board for the Buderus Logamatic heating control unit. If you want to optimize or upgrade your heating system, this is the most effective way, to get the data for the minimum forward temperature possible and to make a decision on the right new heating system (like a heat pump).More Info -)If you are interested, how I got to the current design and why I did this project, have a look at my blog. This is quite essential to get the relevant data from the heating system and can also be used to control it. TL DRThe module is a simple way, to connect the widely used (at least in germany) Buderus Logamatic 2107M control unit for oil based heating systems to your home network and your home automation. ![]()
