Issue: Controller restarts and very slow Webinterface

katze2k · 2024-06-03T19:22:07.052Z

Hi there
i have created my battery with 16s 280Ah Cells and it works so far - with issues:
I use v4.50 Boards with 10k firmware - have a roundtrip time of 800ms and no communication erros to modules or BMS-CAN to VictronCerbo - fine.
But Controller reboots every 10 to 30 minutes (now i have disabled InfluxDB v2 and think controller does not reboot)
The WebInterface needs up to 2 minutes !!! to load a page - and has a ping of 1000 to 2000 ms. so it is often not in sync and i have to reload page.
I think the controller has a cpu load of almost 100% (or more which causes reboots)

Can i have done something wrong while flashing which causes that behavior? (like cpu frequency or flash frequency) or any idea what i can do to find out thats wrong?

I have flashed 2023-12-27 firmware

try to replace esp32 (use f.e AZDelivery) and install 23-04 fw.

I ve solved this issue. It was caused by the Access Point which i have replaced by a UniFi device. Now Performance is perfect and no reboots.
