homebridge-tado-ac

Homebridge Plugin for tado° Smart AC Control.

Requirements

check with: node -v & homebridge -V and update if needed

Version 4 - What's new?

Completely refactored the entire code! that should solve most of the issues the plugin had before + added a few new features.

NEW:

• Support for Homebridge Config UI + HOOBS UI
• Latest HomeBridge API - Not delaying Homebridge startup anymore.
• Support for DRY mode
• Support for AUTO fan speed in all modes (when available, 0 fan speed will equal auto fan speed)

CHANGES:

• occupancyPollingInterval - Always polling (minimum every 3 seconds)
• weatherPollingInterval - Always polling (minimum every 1 minute)
• Weather Sensor "Solar Intensity" is now a LightSensor accessory, representing the amount of sunlight between 0 to 100 (show as Lux)

DEPRECATED:

• autoFanOnly- removed since auto fan speed can be achieved by setting the fan speed to zero.
• disableHumiditySensor - no use for that.
• cachedSettingsOnly - the plugin is not delaying the Homebridge startup and therefor it will always try to fetch fresh data and will only use cache when live data is not available.

FIXES:

• Fahrenheit is finally fixed!
• Fixed homebridge v1+ crash
• Fixed forgetting last target temperature

Configurations

Advanced Control

Auto Detect Configurations

The plugin will scan for all your devices and retrieve each device capabilities separately. that means, that in HomeKit you will see only the things that the tado° app allows you to control.

In practice:

• Minimum and Maximum temperatures are taken from tado° api.
• Temperature unit (Celsius/Fahrenheit) is taken from tado° api.
• COOL/HEAT/AUTO modes are available in the AC states in HomeKit only if it is available in tado° app.
• Modes "FAN" and "DRY" (dehumidifier) will create their own accessories only if you have this ability inside tado° app.
• Fan Speed ("Rotation Speed" in Home app) And Swing ("Oscillate" in Home app) will show in the accessory settings, but only if you have this capability in tado° app.
• Installation type Thermostatic/Non-Thermostatic will create the proper accessory Thermostat/Heater-Cooler.

State Polling

The accessory state will be updated in the background every 30 seconds, this will allow you to create automations based on room temperature or humidity you get from the tado° device. The state will also refresh every time you open the "Home" app or any related HomeKit app.

Ro change the time between each state polling, modify statePollingInterval in the config. to prevent Homebridge from polling the state in the background, set to 0.

Fan Mode

If your tado° app can control your AC FAN mode, this plugin will create extra fan accessory in HomeKit to control the FAN mode of your device.
it will also include all the fan speeds and swing possibilities you have for FAN mode.

To disable the extra fan accessory, add "disableFan": true to your config.

Dry Mode

If your tado° app can control your AC DRY mode, this plugin will create extra dehumidifier accessory in HomeKit to control the DRY mode of your device.
it will also include all the fan speeds and swing possibilities you have for DRY mode.

To disable the extra dehumidifier accessory, add "disableDry": true to your config.

Fan speeds & "AUTO" speed

Fan speed steps are determined by the steps you have available in the tado° app. Since HomeKit control over fan speed is with a slider between 0-100, the plugin converts the steps you have in the tado° app to values between 1 to 100, when 100 is highest and 1 is lowest. if "AUTO" speed is available in your setup, setting the fan speed to 0, should actually set it to "AUTO" speed.

History Storage

Enabling this feature will keep all measurements of temperature and humidity and will store them. Then, all the historic data will be viewable in Eve app under the accessory in a nice graph.

To enable the history storage feature, add "enableHistoryStorage": true to your config.

Specific Device Custom Settings

Some of the config fields allow to set settings for specific devices.

This can be achieved in the config settings ONLY and not through the UI (using the UI plugin settings will erase the custom configurations).

To customize specific device, you'll need to add the device/zone ID or name to the desired config field in an array, see the following examples:

"disableFan": ["Living Room"] (disable fan in single zone with name)

"disableFan": [1, 2] (disable fan in 2 zones with ids)

"disableFan": [1, "Kids Room"] (disable fan in 2 zones mixed id and name)

"disableFan": true (disable fan in for All)

"disableFan": false (disable fan in for None)

Supported fields:

• manualControlSwitch
• disableFan
• disableDry
• extraHumiditySensor
• forceThermostat
• forceHeaterCooler
• disableAcAccessory

Thermostatic Control

When the plugin recognize that your device is on thermostatic control it will create a thermostat accessory in HomeKit instead of the HeaterCooler(AC) Service, thermostatic control will disable the fan, dry, fan speed & swing abilities but give you easier control over the device.

If you're interested in thermostat accessory even in non-thermostatic control, it can be achieved by adding "forceThermostat": true to your config.

Weather Sensors

Enabling this feature will add 2 sensors to your home:

• Outside Temperature - Temperature sensor that will show you the temperature outside, in your home location.
• Solar Intensity - Light Sensor that will show you the relative(%) brightness of the sun in your home area. Due to HomeKit limitation, it will be presented as "lux" with values between 0 to 100

All data is gathered from tado° API and is related specifically to your home location.

Those sensors are great for setting automation based on the weather condition, for example:

• When the first person arrive, If Outside Temperature is lower than 18ºC, Then, Turn on the heat.
• When Solar Intensity is 0, Then, Turn on the Hall Lights & close Blinds.
• When Solar Intensity is lower then 20, Then, Turn on the Garden Lights.

If not set otherwise, the plugin will check for weather changes every 5 minutes.

Occupancy Sensors

Enabling this feature will add Occupancy Sensors for each user signed up to your tado° home (and enabled location services on their device). If not set otherwise, the plugin will check for the occupancy status every 10 seconds.

"Anyone Sensor" will be added automatically to easily automate actions when the first person arrives home or the last person leaves. this is a better alternative to Home App Arrive/Leave automations since this will not require approval for triggering automation. to remove this accessory, set anyoneSensor to false

Troubleshooting

• Auto mode in the home app - because tado° app does not support temperature for Auto mode, changing the temperature will not change anything in tado°.

• HomeKit Cooling or Heating mode while in Auto Mode is set by evaluation I'm making with the room temperature so no promises there.

• If the plugin can't detect your AC installation properly (Thermostatic/Non-Thermostatic), that is probably because the tado° API is not updated with your recent change. you can force it to be the type oif device you want by using forceHeaterCooler or forceThermostat.

• You might see errors like Initializing platform accessory 'Living Room tado°'... HAP Warning: Characteristic 00000025-0000-1000-8000-0026BB765291 not in required or optional characteristics for service 0000004A-0000-1000-8000-0026BB765291. Adding anyway...
  You can ignore these errors as those are cause by adding unnatural Characteristics like the humidity sensor to the HeaterCooler or the On Characteristic to the Thermostat.

Report Issues & Debug

If you experience any issues with the plugins please refer to the Issues tab or Tado-AC Discord channel and check if your issue is already described there, if it doesn't, please create a new issue with as much detailed information as you can give (logs are crucial).

if you want to even speed up the process, you can add "debug": true to your config, which will give me more details on the logs and speed up fixing the issue.
