Modbus integration - Alexander - 20.12.2021
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?

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:

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
