use 0.5 degrees as temp setting? #92

Closed rwijnhov closed 2 years ago

rwijnhov commented 2 years ago

Is it possible to set the temp on 0.5 degrees somehow? I would like to use a temp setting of 22.5 degrees if that is possibe somehow?

kARTechnology commented 2 years ago

yes possible with latest firmware. but in my case if u turn off the ac and back on it loses the precision. dont know why.

absalom-muc commented 2 years ago

Tsetpoint supports a resolution of 0.5°C, just added this information to the documentation.

back on it loses the precision. dont know why

I can't confirm this behaviour for my AC, the resolution of 0.5°C is still given after a power off/on cycle.

What firmware update?

rwijnhov commented 2 years ago

I already use v2.5R21

rwijnhov commented 2 years ago

Ok if i am reading the documentation right I should be able to set to .5 degrees on this firmware. But that isn't possible only full degrees. So is that a bug? I guess same issue as kartechnology. I use this to controll:

platform: mqtt unique_id: AircoKeuken name: AircoKeuken initial: 22 min_temp: 18 max_temp: 30 modes:
- "auto"
- "dry"
- "cool"
- "fan_only"
- "heat"
- "off" fan_modes:
- "1"
- "2"
- "3"
- "4" mode_command_topic: "AircoKeuken/set/Mode" mode_state_topic: "AircoKeuken/Mode" temperature_command_topic: "AircoKeuken/set/Tsetpoint" temperature_state_topic: "AircoKeuken/Tsetpoint" fan_mode_command_topic: "AircoKeuken/set/Fan" fan_mode_state_topic: "AircoKeuken/Fan" current_temperature_topic: "AircoKeuken/Troom"

Please check topic cmd_received and provide a log file.

rwijnhov commented 2 years ago

I have it working now. I had to add temp_step: 0.5 and now can do .5

absalom-muc commented 2 years ago

I believe the issue was addressed, therefore closed. If there are further questions, please feel free to re-open it.

You can set 24,24.5,25 like that only in 0.5 degree precision.
