Hi everyone I have fancoils that can be managed via modbus but i cannot use standard modbus integration from home assistant to set climate devices because i have to read/write single bits of some registers to read/set actions. In particular we have:
- reg 0 : current temperature (r)
- reg 201 : target_temperature (r/w)
- reg 233 : operation mode: heat (3) / cool (5)
- reg 201 - bit 1,2,3 : fan mode (auto 000/ min 001 / night 010 / max 011)
- reg 201 - bit 8 : stand-by on/off
So for example if I need to set fan mode to “night” without touch the other bits i need to: get current value from register 201, set bit 1 and 3 to “0” and finally set bit 2 to “1”. Translating to a template we have:
{{ states('sensor.fc_soggiorno_prg') | int | bitwise_and(65530) | bitwise_or(2) }}
In order to do that I have created modbus sensor and template_binary_sensors that read info from fancoils and custom_components from jcwillox-hass-template-climate to create template_climate_entities. The .yaml configurations are like so:
configuration.yaml

The problem is that i cannot do any action with the climate_template entity. All values are read in the correct way and if i change register values via command-line with modpoll changes are reflected correctly but if I try to set something from the template_climate entity nothing happens and the original value is restored.
If I try to run modbus_write_register services alone in the home assistant developer tab they work.
In the logs i get the following:
[homeassistant.helpers.script.soggiorno] Soggiorno: Running script requires passing in a context
I miss something but i cannot figure out what’s wrong… Can someone tell me what’s wrong?
