Grafana dashboard

To use Grafana you need to have Prometheus and Grafana (v10 or newer) installed. Config for Prometheus:

    static_configs:
        - targets:
            - IP-TO-Mitsubishi2mqtt

Then add Prometheus as a datasource in Grafana Grafana -> Connections -> Add new connection -> Prometheus -> Prometheus server URL: PROMETHEUS-IP:PORT

Then you can import the dashboard in Grafana -> Dashboards -> New -> Import and upload the file https://github.com/gysmo38/mitsubishi2MQTT/blob/master/Mitsubishi2mqtt.json

If you like my work and use it ;)
