I’ve successfully integrated my 10 X 48v 100ah Ruixu server rack batteries pulling full cell-level telemetry using ESPHome and modifying some existing repos.
However, I do need some help with some stability challenges.
I am seeing errors int the logfile :
15:17:48][W][component:237]: Component seplos_modbus took a long time for an operation (413 ms).
[15:17:48][W][component:238]: Components should block for at most 30 ms.
I’m not sure I can do much about this?
But my bigger concern is crashes.
This integration pulls metrics for 10 batteries. I’ve offset the timing of each pull via the “update_interval” , a technique suggested by some other repos, including the one I forked… Intervial is set to roughly every 5 seconds, and I’ve offset the seconds so most updates won’t run at the same time.
I am getting crashes about every 20 minutes with “Reset Reason” set to: “Software Reset CPU”.
Guessing the crashes are related to the shrinking Heap Block
I’m also guessing the issue is the amount of data I’m trying to return, but that really is just a SWAG.
I’m not seeing a lot of help in the logs.

Can anyone point to good practices for managing memory on ESP32 S3?
Also, can anyone suggest tips on resolving this?
