Interesting. Last week my average cpu utilization was around 35%. (PI3b+, hass.io 1.10, supervisor 130, HA 0.78.2)
Upgraded to supervisor 131… okay, no issues, went well.
Upgraded to hass.io 1.11, cpu utilization averaging 20%. Kool! and no issues.
Upgraded to HA 0.79.0, cpu utilization averaging 11%. Very kool! and no issues.
Dunno what your doing but… keep it up.
(maybe in a couple months I can just throw away the cpu)
