Cerbo digital and analogue input names

The names for the digital inputs are all pre-defined but there is no option for , for example, 'Other'. Could this be added as there is a high probability that an input will be used for something that is not defined in the list - I can think of lots of possibilities.


Also, in the Modbus TCP register list, register 3424 Type the generator type 9 is missing.

Try the following:

  • Choose input type: Settings > IO > Digital Inputs:
    • Choose type to select best match state options
      • Generator = Running/Stopped
      • Pump = On/Off
      • Door = Open/Closed
      • Alarm = Alarm/OK
  • Name the Input: Device List > Select Digital Input Device > Device > Name > Custom Name

  • Same applies to Analogue inputs.

Ok, great, that works for renaming and giving a sensible name.

It's not reflected in the modbus data though. I selected Bilge pump (returns 3 in register 3424) and renamed my input to Fan. The modbus still returns a 3 as the Cerbo thinks it is still a pump type even though it's renamed.

I realise this is what is expected but I think if you can customise a name then you should be able to change its type number as well (for a custom one) as if you are using modbus then there is no way to determine the fan is not a pump.


Also, for whoever maintains the modbus register list, don't forget type 9 (generator) is missing.
