Hi to all.
I need to act in case of my temperature node is not updating the value since time. Practically when the screen shows a "red line" on the upper left side, I need to get the bad status and provide an action. I searched on forum with no success. I tried to use ".lastUpdate.minutesAgo" but it seems not to be the right way.
May someone help me to finde the right parameter to check?

.lastUpdate.minutesAgo should work for you

from the docs

Thanks for the answer. The value of ".lastUpdate.minutesAgo" seems not to be the right solution because it continues to be increased in any case, regardless of the temperature value and the status of the "red" or normal indication.
