8 degree setting temp setpoint 8-13

[felleal]

When selecting special mode "8 degrees" with the IR-remote this allows a temp setting of 8-13degreesC which is not allowed as setpoint values in ESPhome. When I tried adding

climate:
visual:
min_temperature: 8
max_temperature: 27

this doesn't help as it doesn't seem allowed by the Toshiba unit. Is the 8 degree setting verified?

The plugin has hardcoded min temp 17 and max temp 30 as that's what my AC unit allows. I don't have 8 degree feature so I can't verify if and how it works.

The issue is somewhat related to my question, so I'll shamefully hijack it :)

I'm not getting HiPower mode (or any special mode) and uart_debug does not show any messages when I turn on/off HiPower from the remote.
So I am wondering if there are some settings during the setup handshake.

@pedobry
What unit did you test this on and did you sniff uart from an original adapter (like RB-N105S-G)?

My unit is RAS-18PKVSG-E/RAS-18PAVSG-E
This Product Bulletin says HiPower is supported, but I don't get if the yellow colored features were added to the new adapters, a FW update of all adapters or something else.

Additional feature by FCU software

I am thinking of buying one to see how it talks to the AC.

Well, a better look at that bulletin explains it ...

FCU serial number

Mine is older, before 9220001.

I have unit RAS-B13PKVSG-E.
I don't have the original adapter - the communication was recorded and analyzed by Toremick here - https://github.com/toremick/shorai-esp32

The handshake is still undecoded - we just replay what the original adapter sends. I know the handshake contains unit model name and it's capabilities, but I have no means to decode it.

The issue is settled for me :)
Meanng, my AC is old enough so only basic functions can be controlled through uart.

The 8 degree setting indicates ok on my indoor unit with a dedicated symbol when engaged both from the esp or the ir-remote. The problem is just that the lower temp setting in degrees C dont work with the plugin for some reason. Even though i allow a lower temp with climate: Thing is ESP also reads (in debug) higher temp setting in the 8 degree-specialmode than the IR remote actually tells/sets. For exampel 13 degrees is indicated as 28 degrees

Try loading the component locally and change these in toshiba_climate.h

static const uint8_t MIN_TEMP = 17;
static const uint8_t MAX_TEMP = 30;

Hi everyone, I have implemented the necessary code to handle the "8 degree" (frost guard) setting correctly. Unfortunately the Homeassistant interface is not updated when the temperature setpoint MIN and MAX changes due to the special mode, does anybode know how to force an update to these settings?
