Myenergi Zappi automation that manages daytime charge

[Dave Foster]

This automation manages the Zappi charger and switches it on and off depending on a number of conditions, such as home battery charge, solar generation and time of day.

Firstly set up a helper toggle which is used to change the priority given to the home battery, it the toggle switch is on the home battery will be allowed to charge from solar and the Zappi will be kept stopped, if the switch is turned off the Zappi will get priority but there has to be enough solar generation to cover the minimum use (1.4kw) and the home battery must be above a certain SoC.

The automation is active between 7.15 and 20.45

This is the setting for the helper toggle

This is the visual editor for the automation -

This is the automation code (note i’ve changed my zappi serial number to 87654321 and you will need to select your device for the notifications.

alias: Zappi Change Mode for EV Charging
description: >-
  Will change Zappi mode to Eco if the EV plug is in AND the battery is greater
  than 45% AND Zappi mode is Eco+ - otherwise sets Eco+
