Hey everyone,

I wanted a way to add my uRADMonitor sensors to Home Assistant without relying on REST sensors and YAML templates, so I vibe-coded an unofficial HACS integration for it.

It currently supports:

– Local API access through the device’s /j endpoint
– Cloud API access using the uRADMonitor User ID and User key
– Multiple uRADMonitor devices
– Separate Local and Cloud entities for the same physical device
– Automatic identification using the uRADMonitor device ID
– Sensors such as temperature, humidity, pressure, radiation, VOC, CO₂, formaldehyde, PM2.5, voltage and uptime
– English and Swedish translations

I have personally tested it with a uRADMonitor A3 using hardware version 104 and software version 124. Other models may work, but I have not been able to test them yet. Some Model A and Model A3 mappings have been added based on known device information.

The canonical project repository, documentation and issue tracker are hosted on GitLab:

This is an unofficial and experimental community integration. It is not affiliated with, sponsored by or endorsed by uRADMonitor or its manufacturer.

Feedback about other models, available sensors and API responses would be very welcome.
