Modbus integration

Hi,

I have manage to read temperature values in LM, but I am struggling with these on my uploade image.
Not sure how to write these in my .json file.

I added my profile.

Did you try adding "writable": 1 to your profile?

[admin]

Also check the maximum temperature register address. It should be 38 not 36.

Where do I check that?

But how can I add this in my profile:

[admin]

Maximum temperature:
   

For Hot water demand add this to the mapping array:

Code:

{
  "name": "Hot water demand",
  "bus_datatype": "uint8",
  "datatype": "uint16",
  "type": "register",
  "address": 56,
  "writable": true
}

Hi, thank you for that. 
How does I map this function. I've tried this:
{ "bus_address": "12/0/7", "name": "Kjøremodus", "bus_datatype": "7", "datatype": "u8", "type": "register", "address": 237 }, 
Butr this gives me value 1 all the time. Should get 0 for Auto, 1 for Manual and 2 for Ad.heat.

Try with "dataype":"uint16" as "u8" is not a valid datatype. See https://openrb.com/docs/modbus.htm
