The gui-v2 (and v1) show this voltages with 3 digits. A modbus request delivers only 2 digits. Also the VRM has only 2 digits.
Currently only gui v1shows 3 digits, the new UI shows 2. This is down to the older version displaying a text field and the new UI has the field defined as a numeric value and is currently rounded to 2.
You can just use a custom node and call /system/MaxCellVoltage and it will show the 3 digits, as defined in the register doc.
NodeRed?
Your picture is mqtt.
modbus delivers only 2 digits.

/100 => 3.42V and 3.44V
Schade…
v3.70, in my cerbo v3.67 are 3 digits shown, see my first post…
LFP cell voltages are important in mVolts, so three digits are very useful.
3.455 - 3.464 are 3.46 ….. mhhhh, a range of 9mV
My bad. You can get 3 via nodered.
