Meter MACS for Home Assistant

usersaynoso · March 26, 2026, 12:11am

Hi all,

I’ve just released Meter MACS, a custom Home Assistant integration for Meter MACS prepaid electricity accounts.

If you use Meter MACS and want your account data inside Home Assistant for dashboards, automations, and alerts, this integration is built for that.

What it does

Signs in with your existing Meter MACS portal credentials
Discovers available meters/assets from the portal
Exposes your electricity balance in Home Assistant
Exposes electricity cost per kWh
Adds an electricity supply switch where the required site/asset data is available
Creates a separate Home Assistant device for each discovered asset
Lets you choose which discovered assets stay enabled
Supports reauthentication through the normal Home Assistant UI
Includes diagnostics to help with troubleshooting

At the moment, it’s installed through HACS as a custom repository:

Open HACS
Add this repository as an Integration:
https://github.com/usersaynoso/Meter-MACS-Portal-for-Home-Assistant
Install Meter MACS
Restart Home Assistant
Go to Settings → Devices & Services
Add the Meter MACS integration
Enter your Meter MACS email address and password

The integration uses a polling model
Default refresh interval is 120 seconds
Minimum refresh interval is 30 seconds
If the main API path is unavailable, it can fall back to dashboard parsing
The supply switch is currently optimistic, so it does not yet confirm the true remote state after every toggle

I wanted a clean way to bring Meter MACS account data into Home Assistant so I could:

If you use Meter MACS, I’d really appreciate any feedback, testing, bug reports, or feature suggestions.
