# Important Notice:
DO NOT USE RS485 ON THE BMS - PORT! This port only has a baudrate of 9600, which is too slow for regular updates.
Use the Modbus port.
Configure it to a baudrate (in the Advanced Menu) of 115200. This allows for updates every second.

I didn't notice that we could reconfigure the Modbus Baudrate to 115200 ...

In that Case we can definitively increase the refresh Rate and avoid that the ESP32 crashes / gets stuck if refreshing too frequently.

On my Side I have them maybe disappearing from my Network for a Minute or Two each Day, but I thought that it was more related to the DHCP Server renewing IP Address rather than a ESP32 Crash / Reboot (and I still don't think it's that !).

Would that be in Page 2? I cannot see that Setting in the Advanced Menu in the Manual of the Deye Inverter.

## Hardware diagram

RX / TX between esp and ttl converter way have to be swapped. This seems to be a little different from espboard to espboard.
Check Termination: check that 120 Ohm are between B+ and B- (short wire); for long wire use 120 Ohms on both sides.
If it dosent communicate(RX/TX led both blinking) Try swap rx/tx on the esp.
