The problem

I installed today Nibe Heatpump integration and it's working, so that I am getting data from F1255 with default ports. So quite well already as this was my first ESPhome project :)
-Nibe has latest firmware and connected to myuplink
-HA has all latest modules installed (platform Raspberry Pi 5)

I am using same board and original example configuration, just modifing my network etc (static IP added): lilygo-t-can485.yaml.

Issue: Nibe pump is giving alert after an hour or so. Nibe integration log as attachment.

Log is getting lot of these "due to parse error" -> "wrong checksum". Could wifi connection be too poor?
