Deye MQTT HA Plugin

Introduction

This plugin enables Home Assistant to automatically discover all values published by the "Deye Solar Inverter MQTT Bridge".

Energy usage diagram provided by Home Assistant filled with data from a "Deye solar inverter MQTT bridge":

This integration can read and update the active power regulation feature's value if it's enabled. However, reading and updating the "time of use" (ToU) configuration has not been implemented yet.

Installation

1. Install Deye solar inverter MQTT bridge

2. Expand the Deye Solar Inverter MQTT Bridge configuration file config.env with a customized version of this section:

   # Home Assistant Integration
   # ==========================
   PLUGINS_ENABLED=deye_plugin_ha_discovery
   DEYE_HA_PLUGIN_HA_MQTT_PREFIX=homeassistant
   DEYE_HA_PLUGIN_INVERTER_MANUFACTURER=<your manufacturer>
   DEYE_HA_PLUGIN_INVERTER_MODEL=<your inverter>
   # Topics not published to HA
   # Use : as separator, supports Unix shell-style wildcards *, ?, [seq] and
   # [!seq] as implemented with Python fnmatch,
   DEYE_HA_PLUGIN_IGNORE_TOPIC_PATTERNS=uptime:*/pv[234]/*
   

3. Install the plugin from plugins directory as described in "How to start the docker container with custom plugins" and restart container to activate the changes in config.env.

4. Switch to the Home Assistant and install Utility Meter

5. Configure a Utility Meter helper to reset the daily production counter at midnight.

   # Example configuration.yaml entry
   utility_meter:
     energy:
       name: "Production total (daily reset)"
       source: sensor.deye_inverter_mqtt_production_total
       cycle: daily
   

   or graphically

   

   

Requirements

• Deye solar inverter MQTT bridge version 2024.11.1 or newer

Troubleshooting

1. Ensure that the container deye-mqtt has the required minimum version

2. Check if the plugin has been loaded.

   docker logs deye-mqtt
   

   When starting the container after loading this plugin, a message similar to the following line should appear in the container log.

   DeyePluginLoader - INFO - Loading plugin: 'deye_plugin_ha_discovery'
   

   If this line does not appear, you should check the installation of the plugin.

3. Check log of the deye-mqtt container for errors.

   On demand increase the detail of the logging in config.env to LOG_LEVEL=DEBUG and restart the container.

4. Checking the content published in the MQTT broker. You can use a graphical tool such as the MQTT Explorer for this.
