MST960 reading current values is not possible

[optima-software]

The device MST960 is delivered with a temperature sensor and can trigger to heat or cool.
But it is not possible to get the current measured temperature (sensor or outside), nor the configured target temperature via API. Methods like async_get_current_temperature() are not supported.

Due to this issue, it can not be integrated in home automations.

Are there any ideas how to deal with it?

Hello,
I myself also interested for the device MTS960 handler (https://shop.meross.com/products/thermostat-960).
I thought it will be handle by ThermostatModeMixin class but it's not.

What I have when sync is :
[2024-01-14 14:42:42][DEBUG][meross_iot.manager] : The following devices are new to me: [{"uuid": "2307143728429860080148e1e9d14236", "online_status": "ONLINE", "dev_name": "Thermostat cumulus", "dev_icon_id": "device_mts960_eu", "bind_time": "2023-12-28T18:21:36", "device_type": "mts960", "sub_type": "eu", "channels": [{}], "region": "eu", "fmware_version": "4.2.6", "hdware_version": "4.0.0", "user_dev_icon": "", "icon_type": 1, "skill_number": null, "domain": "mqtt-eu-2.meross.com", "reserved_domain": "mqtt-eu-2.meross.com"}]

And this :
[2024-01-14 14:42:42][DEBUG][meross_iot.device_factory] : Building managed device for Thermostat cumulus (2307143728429860080148e1e9d14236).

So it seems to handle ElectricityMixin and ConsumptionXMixin which is great.
It should handle also ThermostatMixin and not ThermostatModeMixin I guess that should be added in MerossIOT because not exist yet.

We will be please @albertogeniola if you can add it to the code :)

Sincerely,
Jérôme

Hello,
In abilities I saw this :

 'Appliance.Control.Thermostat.ModeB': {},
 'Appliance.Control.Thermostat.ScheduleB': {},
 'Appliance.Control.Thermostat.CtlRange': {},
 'Appliance.Control.TempUnit': {},
 'Appliance.Control.Thermostat.Alarm': {},
 'Appliance.Control.Thermostat.AlarmConfig': {},
 'Appliance.Control.Thermostat.CompressorDelay': {},
 'Appliance.Control.Thermostat.Frost': {},
 'Appliance.Control.Thermostat.Calibration': {},
 'Appliance.Control.Thermostat.DeadZone': {},
 'Appliance.Control.ConsumptionConfig': {},
 'Appliance.Control.Sensor.History': {},
 'Appliance.Control.Thermostat.Timer': {}}

I saw Thermostat abilities but not matching the actual list :

 CONTROL_THERMOSTAT_MODE = 'Appliance.Control.Thermostat.Mode'
 CONTROL_THERMOSTAT_WINDOWOPENED = 'Appliance.Control.Thermostat.WindowOpened'

So I test something : I update file enums.py to modify Mode > ModeB and update file thermostat.py to modify get('mode') to get('modeB'). I reach to get a ThersmostatState that gives me these keys :

Code is

therm=dev.get_thermostat_state()
logger.debug(therm._state.items())

Result is
dict_items([('channel', 0), ('mode', 1), ('targetTemp', 1900), ('working', 1), ('currentTemp', 1626), ('state', 1), ('onoff', 1), ('sensorStatus', 1)])

With this results, some commands on ThermostatState works like current_temperature_celsius (temperature should be divided by 100 and not 10 by the way).

@albertogeniola I can work on this if you want to :) If I write some codes do you want a new mixin or I order to make it work in ThermostatModeMixin ?

Sincerely,
Jérôme
