I’ve tried to reproduce this problem with no success. Set my HASS to do the 10 second poling, defined one of the inputs with a really long name, ran it for the last 12 hours and got no heap degradation.
There are no other HA users reporting this problem. So Maybe we need to revisit from a different perspective. I’m going on these reported observations:
Since I can’t reproduce it, I’ll have to rely on trying things on your end. First thing I’d like to do is try changing the HASS update interval back to 30 seconds, or even a minute. Can you do that and report back please? If it continues to fail, can you post the heap trace and message log please?
