If a sensor is configured to alarm on a limit and it hasn’t been heard from in 3 times normal interval (+/-?) a “missing sensor” alarm must be displayed by station and an email sent.
For example a sensor configured with temperature low limit at 0C and no station or gateway has received a packet from it in 1 minute(+/-?) its battery may have been exhausted, it may have gotten wet or ben damaged or maybe something is blocking the radio.
Sensor availability alerts are planned and may be exactly the thing you’re looking for (Ruuvi Gateway, subscription). More info will become available once the feature is in development.
Sensor availability alerts notify you if any of your sensors stop sending data to the cloud (empty battery, connection issue, or other reasons). The feature is scheduled to be available in Q2 2023.
