[ERROR ] - Setting Charge Rate failed: ('ZeroDivisionError', 'write.py', 447)

I have started to get the following message in the log files. Overnight charging stops and Predbat fails. Requires restart of GIVTCP and Predbat.

While there are a couple successful writes, the rest of the log until restarting is only ZeroDivisionError messages.

Running GivTCP Current version: 3.0.4 on a HAOS Pi5.

All three devices are connected using ethernet.

Only configuration change of note is that the parallel AIO was installed a few weeks ago and influxDB was installed on the HAOS aboiut two weeks ago.
