Well, not sure what the difference is. A battery level is a battery level 😉 Problem with the ‘card error’ is, it is a sending device, not a receiving one. So an empty battery or lost connection doesn’t ‘error’ a card, Homey doesn’t know if it’s offline, and the last known value is just the actual value. With f.i. zigbee sensors it’s a similar situation. When they lose connection (but not actually left network) _to Homey_, it’s nothing more then a sensor which doesn’t update anymore, and “nothing’s wrong”.

Sometimes, you’ll discover a sensor or other device doesn’t report it’s status or value anymore, but it does NOT notify you of being offline… Well, this flow checks the, most recent update time of your sensors. You can run the flow every day, twice a day, just add or remove a time triggercard. The ‘inactive time’ can be edited as well (24hrs as default) and you can choose to not send notifications when all sensors did report inside the ‘inactive time… --- _[View the full topic](https://community.homey.app/t/app-pro-xiaomi-mi-flora-sensor-ropot-app/45)._
