Home Assistant - Adjusting solar settings

Introduction

SolarAssistant provides solar device settings in the correct format for it to be controlled from Home Assistant. This guide below assumes you already have Home Assistant integrated with your SolarAssistant.

Step 1 - Open advanced MQTT settings

Under the "Configuration" tab, open advanced MQTT settings.

Step 2 - Disable setting changes (temporarily)

Disable setting changes over MQTT. This is so that we can test setting changes without affecting your solar system.

Step 3 - Start the MQTT broker

Under the "Configuration" tab, start the MQTT broker.

Step 4 - Add a settings card to Home Assistant dashboard

Under the "Configuration" tab, start the MQTT broker.

In the bottom right corner, select add card.

Select the entities card.

Add the solar setting you want to edit from the dashboard. In this example we are adding the inverter "Output source priority". Add the response sensor which will display the setting change result.

Go out of dashboard edit mode.

Step 5 - Test adjusting solar setting

Set the solar setting on the new card.

We expect to receive a Error: Updates not allowed response. This message is sent from SolarAssistant when it receives an instruction to change a setting.

If you do not get a response from SolarAssistant, you are most likely running an MQTT broker in HomeAssistant that isn't passing your setting change message to the SolarAssistant MQTT broker. Please have a look at the topic out configuration of the broker configuration page.

Step 6 - Allow MQTT setting changes

Go back to the advanced MQTT settings we set in step 2. Now that the integration is working, we can allow adjusting settings.
