Running 3.0.2 - Release Build on a Pi 4 and TP-Link Smart Home Binding 3.0.2. with ZRAM enabled.
After some hours I get a ton of COMMUNICATION_ERRORs:

Rebooting doesn’t help (good thing). Only “fix” that works is to remove/reapply power to the HS-220 (not good).
I’m trying changing the polling interval from 1 to 10 but while I’m waiting to see if it helps, I’d appreciate any other ideas.
Update: changing the polling interval only delayed the error reporting:
