Ruuvi HomeAssistant Integration, notify when battery dies

techplex · January 29, 2024, 7:29pm

Hello!

I’ve got 10 Ruuvis around my house measuring many different areas from the attic to the basement.

I’m using Home Assistant on a Raspberry Pi 4 to log and view the data from the Ruuvis.

Has anyone figured out how to setup notifications for when the Ruuvi’s battery dies or it goes out of range?

Thank you for your message! Have you reached out to Home Assistant support or user community yet? https://community.home-assistant.io/

@techplex has a very good question. With other integrations we have a percentage for the battery and we can warn when it is below 20% as an example. But we only have a battery voltage in the Ruuvi Station app as well as in Home Assistant. If we could get a percentage for the battery it would be great. A timestamp for the last message would also be nice.

Hello @Raderarn , thanks for the suggestion. The Home Assistant integration for Ruuvi products is developed and maintained by third party developer. Please suggest this feature at RuuviTag BLE integration page

But I miss the battery percentage in Ruuvi Station as well!

We currently show voltage in sensor settings page under more info. We have considered showing percentage in the past. If you feel this should be reconsidered, please post a suggestion under feature requests.

Ok, I will do that, thanks!

Only a year late. But I fed up to manually following voltages and built myself a tool for alerting for low battery.

Original blueprint:

https://gist.github.com/sbyx/1f6f434f0903b872b84c4302637d0890

low-battery-level-detection-notification-for-all-battery-sensors.yaml

blueprint:
  name: Low battery level detection & notification for all battery sensors
  description: Regularly test all sensors with 'battery' device-class for crossing
    a certain battery level threshold and if so execute an action.
  domain: automation
  input:
    threshold:
      name: Battery warning level threshold
      description: Battery sensors below threshold are assumed to be low-battery (as
        well as binary battery sensors with value 'on').

My version for ruuvitags (selects all sensors that end with _voltage), should maybe hopefully work:

blueprint:
  name: Low battery level detection & notification for ruuvitags. 
  description: Regularly test all ruuvitags for crossing
    a certain battery level threshold and if so execute an action.
    Ruuvitag says that 1800mV tag should still function but it depends on temperature etc.
    1900 mV during -10C seems to be too low for my units but YMMV

And if you want to alert if the tag is no longer showing, automation that activates when state goes to undefined and waits for xx hours/minutes/seconds if things change and if not, does something should do the trick.

I for example created a template sensor that primarily uses ruuvitag but if it is not available it’ll grab temperature information from weather forecast plugin. If you have some applications where you rather have some estimate than automation just stops working when tag is not in range/similar.
