I'm having the exact same issue with my Wave. I'm wondering if there is a slight difference between the BLE output of the Wave Plus, which the integration was designed for, and the Wave.

galambert75 commented 2 years ago

There's a custom Home Assistant addon that works for all three (Wave, Wave Plus, Wave Mini). Not sure if this is using active or passive BLE. Unfortunately, I don't have the programming skills to contribute code...

However, I'm looking to use an ESP32 so I don't need to have the Wave within a certain radius of the HA server.

I'm having the same issue, the addon didn't work consistently for me. It would cycle between which device it was going to pick up. It would be random between my mini and plus and once in a blue moon I would have both. Migrated to esphome for hopefully reliability and ran into this.

Turns out there's already a feature request for this: https://github.com/esphome/feature-requests/issues/1467

I would recommend we all upvote.
