Jarno Rankinen ce1c569564 Methods for reading and writing single holding registers. Unfortunately the writes don't seem to have much effect, the registers are reset after a short period or instantly. Maybe due to something with the library, but no errors are produced. Closes gh-5 2023-03-02 14:24:05 +02:00

Enervent-control

External control of an Enervent Pingvin Kotilämpö residential heating/ventilation unit via RS485 bus using the Modbus protocol.

Work is my Bachelor's Thesis at Oulu University of Applied Sciences, software development.

The Python version under enervent-ctrl-python is an initial proof-of-concept, mainly to test that the hardware side of things works as expected. The main daemon is written in Go and the source is under enervent-ctrl-go

The daemon is designed to run on a Linux host that has some sort of RS485 connector attached. For development a Raspberry Pi 4B was initially used for convenience, but after the Go implementation started, a RPi Zero W 1 with a connected Zihatec RS 485 HAT has been used to make sure the daemon stays as lightweight as possible.
