Good evening,
I was already looking for while for an EV Walbox that could be quite easily controlled local by Home Assistant.
I found the Peblar Home and this device has the possibility to use a local REST API or MODbus API.
I am not a programmer but with some ChatGPT help(
) I got it it running!
Unfortunate there is no Integration available but it wasn’t too difficult
Below link for the API details:
https://developer.peblar.com/
very cool! any chance you will publish the code as an addon? I’m thinking of buying a charger from Peblar.
yes of course! it is just a YAML file. I created a separate yaml file (peblar_charger.yaml) instead of putting it in my configuration file. this to keep the configuration file clean.
you can simply create this yaml file and add below to your configuration.yaml file:
homeassistant:
packages:
peblar_charger: !include peblar_charger.yaml
below the configuration for the Peblar REST API, I saved this as peblar_charger.yaml
#Key Configuration Elements:
# REST Sensors: These sensors retrieve data from the API endpoints and display it in Home Assistant. Replace <local_ip> with your device’s IP address and <your_api_token> with the actual token.
# REST Command: This allows you to change settings via the API, such as setting the charge current limit.
# Input Number & Automation: This example uses an input_number to set the charge current limit and an automation that triggers the REST command when the value changes.
#
# Customization:
# Modify the scan intervals as necessary.
# Add more sensors or commands based on other available API endpoints.
