nilan2mqtt's Introduction

Quality Gate Status

NOTE: Development is in progress.

nilan2mqtt fetches Nilan (R) heatpump CTS700 readings and settings via modbus and sends them to MQTT broker in regular intervals. It also executes commands retrieved from MQTT. Compatible with Home Assistant.

Environment variables:

  • NILAN_ADDR - Nilan heatpump address, including port. E.g. 192.168.1.15:502
  • MQTT_ADDR - Address of MQTT broker, e.g. "192.168.1.18:1883"
  • MQTT_USER - (optional) MQTT broker username
  • MQTT_PWD - (optional) MQTT broker password

Local build and run

go get all
go build -o nilan2mqtt cmd/nilan2mqtt/main.go
NILAN_ADDR="<heatpump addr>" MQTT_ADDR="<MQTT broker addr>" ./nilan2mqtt

Docker build

docker build -t pjuzeliunas/nilan2mqtt:dev .

Docker run

docker run -e NILAN_ADDR="<heatpump addr>" -e MQTT_ADDR="<MQTT broker addr>" --restart=unless-stopped --net=host --name=nilan2mqtt -d pjuzeliunas/nilan2mqtt:dev

Also available in DockerHub: pjuzeliunas/nilan2mqtt

nilan2mqtt's Issues

exception '2' (illegal data address), function '131'

When starting the docker, the log starts showing fetch errors.
Any suggestions on how to troubleshoot?

I read that the modbus adresses could differ from the software versions, but not sure if this is the case.
I have a Air9 system as well.

Dead project?

I have been using our implementation for more than a year now, but I want to add some extra values, and maybe implement it as an AddOn in HomeAssistant, so its easier for others to use this great plugin.

Would it be preferable for me to fork the project and proceed with the enhancements independently, or would you prefer a more collaborative approach with me acting as a contributor here?

It's worth noting that while I'm not proficient in Go development, I'm confident in my ability to extend the functionality of your codebase with the extra features I have in mind.

Looking forward to your guidance on the best course of action.
