Thx for your reply and example, but I have from the beginning of homey already a simple flow that wil alert me when a battery is in low condition and also notest that core homey has also a feature for that in the timeline.
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”.
For those ‘silenced’ devices, I have a flow which checks the last reported status every x hrs
That could be an option to try, but find also a simple alternative in the app I did’t noticed before. But for some reason don’t get it working. The Timeout card and sync all sensors card.
Setting the app on 5 minutes interval to test the timeout card doesn’t trigger a reaction. Having some sensors with died battery so I should get an timeout error I assume. Official app gives a timeout when trying to reach it.
I have worked on the smpl Homey App and integrate the smpl mini display. A project @Nitramevo started to create smart e-ink displays for Homey that can show all dynamic data from Homey (see the topic here)
Here are some display layouts I use in combination with the display:
Does it work with those huahuacaocao devices? You actually never know if its the xiaomi, vegtrug or that one when you order. It reports on my phone in BT as “Flower care” but homey does not find it. If it matters, I already have one that is monitored by homey
