I simplified the setup to a single instance of HADB with only ~6 entities that rarely change (it took a few hours for the entities to start showing up in HE). Despite the now trivial setup, I'm still seeing issues. I suspect something on the HA side.
No, it is toggled to ON.
Check.
See below. A couple other tidbits. According to my Hub Info, I'm running a CPU Load on the hub of 50.25 with over 95% of hub busy time being attributed to both the HADB device and the HADB app. I also noticed that strangely 6 of the 7 child devices under HADB have no states shown on the device details view even though the corresponding entities in HA have states and events. Odd. The log continues to spew to the error "com.hubitat.app.exception.LimitExceededException: Device 2269 generates excessive hub load on line 51 (method parse)". Device 2269 is the HADB device.
I'm not sure the above picture is the most effective way to share the screenshot -- LMK if I can do it better/differently. Also I didn't bother to include the full entity list as there are hundreds of entities in HA.
Thanks for looking at this.
