The gateway cannot communicate with the KEBA unit after importing the template. What should I check?

The baud rate stored in the template metadata may be incorrect. Check the KEBA device manual for the actual default baud rate and parity, then update the gateway serial port settings accordingly.

Can I read and write the same register, for example the operating mode?

Yes. Several registers in this template are mapped as both readable and writable at the same Modbus address. You can read the current value and overwrite it from the ModbusCloud dashboard.

Do I need to terminate the RS485 bus?

If the KEBA unit is the last device on the RS485 bus, enable the 120 ohm termination resistor at both ends of the cable. Unterminated buses can cause intermittent communication errors, especially on longer cable runs.

How are temperature values scaled in the registers?

Refer to the KEBA Modbus register documentation for the exact scaling factor. Some KEBA devices use a factor of 10, meaning a register value of 215 represents 21.5 degrees. Confirm this before interpreting dashboard readings.
