Athom mixes the descriptions “CPU usage” and “System load” or “Average load”
→ CPU usage indeed cannot exceed 100%
→ System load can reach 300% or more

My Pro 2019 does not have CPU figures, but it does have this “average load”; however, this is very different from the above % values:
There is also a handy monitor app available: SysInternals
.
A possible cause can be “chatty” devices, same as can occur with z-wave.
Certain Tuya devices are known to ruin / clutter the zigbee mesh by emitting way to much messages; probably certain Niko device types do this as well.
I’ve also read about a dimmer doing this.
Homey just tries to keep up, wich can cause these higher system loads.
BTW a CPU running at 100% is nothing weird, it only throttles down when there’s less to process, to save energy .
.
Depends on how you paired them.
But the description sounds as a range problem, the roller shutters seem to be on the edge of the range. And the range can always vary a bit, due to interference.
