Feature Request: Mimic Tado's Auto-Assist Feature for open Windows detected

[jotzet79]

Hi @seydx,

It would be nice if we could mimic the behaviour of the Auto-Assist feature for "openWindowDetection"

• Expose switch for the Open Window Thermostat Feature using 2 modes (enabled, disabled) and 2 states (on, off):
• If Zone contains the "openWindowDetected" flag, then expose its status to the already exposed Window Sensor and set the switch ENABLED in state OFF (maybe before check status returned by API call)
• Now the user can activate the switch manually or via automation (preferably; based on sensor state) to state ON
• Trigger API Call "Activate OpenWindow"
• Now tado's setting for the Zone's Shutoff duration starts to be counted down (1-3600 secs, depending on the Setting in tado's App)
• Poll if any change from App / WebApp / (Auto-Assist) was done - just for being safe
• After the count down has finished the thermostat is set to normal mode OR...
• The user deactivates the switch manually / via automation to state OFF
• Trigger API call "Deactivate OpenWindow"
• Switch is disabled

Thank you,
Joachim

Hey @jotzet79

I dont know what u mean exactly. Because there is already an option to expose a window sensor AND a window switch (customizable for each zone)

Window Sensor
https://github.com/SeydX/homebridge-tado-platform/blob/master/example-config.json#L83

Window Switch
https://github.com/SeydX/homebridge-tado-platform/blob/master/example-config.json#L84

The "openWindowSensor" triggers on open window detection and the "openWindowSwitch" enables/disables the open window function for the zone AND also triggers the open window detection for the zone

https://github.com/SeydX/homebridge-tado-platform/blob/master/src/helper/handler.js#L265

... and the "openWindowSwitch" enables/disables the open window function for the zone AND also triggers the open window detection for the zone

Hey, unfortunately this is not the case. The openWindowSwitch enables or disables the open window function (which is in Tado app under settings --> Open Window Detection), but it never triggers an open window state. Somehow I cannot make it work as it seems to be intended. How is it possible to trigger an open window state with the plugin?

Same here, I managed to set up automation based on the sensor to disable the heating, but I don't see any way to trigger the "opened window" as if I would press the button in the tado app. The switch only controls the on/off for the feature (the settings flag), it does not trigger it. Maybe I am missing something, but the switch is on all the time (as it should). I'd say we need a third switch for this.

Hey, now as we have a new maintainer @smart7324, we could give this a little poke again:

To workaround the issue of the missing Switches that can be triggered based on sensor state open, I created a CmdTrigger Switch: If enabled the switch fires a locally hosted Script (e.g. Shell in my case). So for each room ID I create a Fake Switch.

{
    "accessory": "CmdTrigger",
    "name": "Foyer Activate OpenWindow",
    "command": "/home/pi/Documents/Scripts/activateOpenWindow.sh 10",
    "stateful": false,
    "debug": false
}

Via automations I react on the sensor state provided by the plugin, which reacts if the JSON for the zone returns a openWindowDetected attribute. If so it switches the Switch from above to "on", which in turn triggers the script function setRoomStateActivateOpenWindow.

function setRoomStateActivateOpenWindow() {
    local roomId="${1}"
    local tadoRoomInfo="$(curl -s "http://localhost:7070/api/v2/homes/${TADO_HOMEID}/zones/${roomId}/state/openWindow/activate" -X POST -H "Authorization: Bearer ${TADO_AUTHTOK}")"
    [[ "${TADO_DEBUG}" = 1 ]] && echo ${tadoRoomInfo} | jq -r
}

function setRoomStateDeactivateOpenWindow() {
    local roomId="${1}"
    local tadoRoomInfo="$(curl -s "http://localhost:7070/api/v2/homes/${TADO_HOMEID}/zones/${roomId}/state/openWindow" -X DELETE -H "Authorization: Bearer ${TADO_AUTHTOK}")"
    [[ "${TADO_DEBUG}" = 1 ]] && echo ${tadoRoomInfo} | jq -r
}

function setRoomAuto() {
    local roomId="${1}"
    local tadoRoomInfo="$(curl -s "http://localhost:7070/api/v2/homes/${TADO_HOMEID}/zones/${roomId}/overlay" -X DELETE -H "Authorization: Bearer ${TADO_AUTHTOK}")"
    [[ "${TADO_DEBUG}" = 1 ]] && echo ${tadoRoomInfo} | jq -r
}

Of course the "solution" of having fake switches is not necessary if the funcionality is built into the biz logic itself, this is only the workaround.

Thank you!
Joachim

PS: I already successfully switched to the tado proxy yesterday (https://github.com/s1adem4n/tado-api-proxy), btw - thanks for your hints!

@smart7324, up until now seydx's / your platform does not support handling Tado's "Open Window Detection", which is supported ONLY via a paid subscription OR a manual interaction by the user.

Basically what it does is

• a thermostat detects a temperature drop
• thermostat / controller is notifying this temp drop to the Tado ecosystem
• Tado Ecosystem reacts and displays a warning in the App that a "Open Window was detected".
• If the user has a paid subription, then the App itself sets the mode to "Open Window" (which means heating is suspended)
• If the user has not a paid subscription, then the user can set the mode to "Open Window" (which means heating is suspended), otherwise the system is heating up the room

With adding tweaked functionality to this Homebridge Tado platform, the paid subscription mechanism can be avoided and the necessary manual interaction via app can be circumvented.

@jotzet79 Thanks for clarifying the feature request! Unfortunately, I don’t think I’ll have enough time to implement, test, and maintain the functionality you described.

I’m working on this project in my free time alongside my full-time job as a full-stack developer, so I mostly focus on fixing critical bugs and keeping the plugin stable and secure for everyone.

That said, I can really recommend using some cheap Zigbee window sensors. You can use them to trigger a HomeKit automation that turns your Tado heating off when a window opens, and back to auto when it closes. I’ve been running this setup for years, and it’s been super reliable.
