I'm also interested if it is possible to use Aqara Thermostat E1 in Zigbee2Mqtt with other temperature sensor (similar to Aqara home app; Maybe something with "bind" ? .... ). |

I can switch from internal to external. But how do i tell it which one is used for temperatur? |

I'm a newbie to HA, but I got this to work (using zigbee2mqtt_edge, but with the current update of zigbee2mqtt this should work without using edge. Otherwise you don't see Sensor Internal/External). This is all info from here. What we are going to do : every change in temperature in the external sensor will be a trigger to update the temperature in the valve. To begin with add your external sensor and give it a name. In this example I will refer to a temperature-sensor in the kitchen and also a valve in the kitchen. Now to get it to work :First in Settings/Addons/zigbee2mqtt under Device/Exposes - set Sensor to External (and this got reset for me a few times so check regularly if it's still External). Then in Settings/Automations and Scenes : Here you need to switch to YAML editor. Press three dots top right and pick "Edit in YAML". Otherwise you get errors and nothing gets saved.Action : #Radiator_Kitchen is my name for the valve in the kitchen It takes sometimes a few minutes to update the current temperature in the SRTS-A01. But it works. |

I can see the /set/sensor_temp being invoked but how do you verify the thermostat actually does the right thing? |

never mind - figured it out. you know it works when the temperature cards starts showing reported temperature that matches the source thermometer. |

I tried to put the code in the automations-configurator, and it didn't work. Now I inserted the code directly into "automations.yaml" and it accepted it. As I said, newbie ^^. But the radiator does not change the temperature to the external temperature sensor. I checked all entities multiple times. I do have firmware 0.0.0_0825 though, but can't update due to an error-code in the OTA section of z2m. Edit: I got it. You have to insert the exact Device ID with upper case letters etc. as shown in the z2m addon under settings "Friendly name*" in the action. |

Hi, Does anybody else get regular timeout errors when setting the temp through Home Assistant? I setup an automation in Home Assistant to update the local temperature with an external temperature when they get outside a certain range from each other. It triggers about once every 5+ minutes when the a radiator is in heat mode and once every 30+ minutes when they are off. Overall it works but it gets timeout errors in Zigbee2mqtt a bit too often to my liking. Is there something I can change to improve reliability? Debug Data: Device Status: Automation Action: |

Thanks. It works for me. Di you know how It Is possibile to set an external temperature device inside TRV ? Afaik It should be possibile to give the external device zigbee id to the TRV. I image there should be some internal non exposed attributes to set , same as sensor_temp |

If anyone is interested, I connected the external sensor to the thermostat using Extension directly in zigbee2mqtt. Change "TermostatBedroom" and "0x00158d0008ce74e7" to your name of thermostat and ID of temperature senzor. Save this code to .js file and place it into extension directory in data directory \data\extension\MyCustomExtesion.js. |

thats what im looking for, although it works with the HA automation i think it unnessasary do use HA for that when its just sending messages from one Queue to another. Need to dive into the Zigbee Plugin stuff, maybe it could even be configurable? |

i improved the idea of @mufsupermuf to have a generic plugin: class ExternalSensorThermostatExtension {
mapping = {
// Temperature Sensor Id : Thermostat Name
"0x00158d00091e7441" : "Thermostat Küche"
// just drop in your pairs here
}
constructor(zigbee, mqtt, state, publishEntityState, eventBus, settings, logger) {
this.mqtt = mqtt;
this.logger = logger;
this.baseTopic = settings.get().mqtt.base_topic;
this.eventBus = eventBus;
// recalibrate the thermostats
Object.keys(this.mapping).forEach(sensorId => mqtt.onMessage(`${this.baseTopic}/${this.mapping[sensorId]}/set`, JSON.stringify({ calibrate: "calibrate" })))
eventBus.on('stateChange', this.onStateChange.bind(this), this.constructor.name);
logger.info(`Loaded ${this.constructor.name}`);
}
async onStateChange(data) {
const { entity, update } = data;
if (!Object.keys(this.mapping).includes(entity.ID)) { // check if Temperature Sensor
return
}
const { temperature } = update;
if (temperature === undefined) { // no temperature update
return
}
// set new temperature value to thermostat
this.mqtt.onMessage(`${this.baseTopic}/${this.mapping[entity.ID]}/set`, JSON.stringify({ sensor_temp: temperature }));
this.logger.info(`The sensor_temp of ${this.mapping[entity.ID]} was set to ${temperature}`);
}
async onMQTTMessage(topic, message) {
}
async stop() {
this.eventBus.removeListeners(this.constructor.name);
}
}
module.exports = ExternalSensorThermostatExtension;i dont know if this mapping can be stored somewhere in the zigbeemq settings stuff somehow @Koenkk ? You could build a simple UI on top of that (to somehow build and store this mapping between sensors and thermostats). |

That would be great to know, maybe it uses a yet unknown command. As a workaround, I'm setting the system mode to off while the window is open - it's working reliably since over a year.
That means that you can't read it on demand. The state is automatically pushed whenever it changes. |

I think it works in such a way that if the open window detection is turned on, the thermostat can detect that the window is open based on the sudden drop in the temperature of the device. Then it informs about this fact by setting the property "window_open". Or something like that... |
Beta Was this translation helpful? Give feedback.
-
|
I think the question was how an external window/contact sensor tells the thermostat that a window is open (you describe the window detection inside the thermostat, i.e., without an external sensor). |
Beta Was this translation helpful? Give feedback.
-
|
I think that's not what it's for. If you have sensor on the window and it reports that the window has just been opened, you cannot tell it to the thermostat. Just close the thermostat at that event. For example by setting "occupied_heating_setpoint" to 5° celsius. |
Beta Was this translation helpful? Give feedback.
-
|
Im doing exactly that with HA automations but thought maybe it could be done more "native" by telling the thermostat the window is open and just let it do its things |

@digitalkaoz Thank you for your Zigbee2MQTT extension. I've slightly updated it to link a sensor to multiple thermostats: class ExternalSensorThermostatExtension {
mapping = {
// Temperature Sensor Id : Thermostat Names
"0x00158d0009cbf894" : [
"Woonkamer radiator links",
"Woonkamer radiator rechts",
],
}
constructor(zigbee, mqtt, state, publishEntityState, eventBus, settings, logger) {
this.mqtt = mqtt;
this.logger = logger;
this.baseTopic = settings.get().mqtt.base_topic;
this.eventBus = eventBus;
// recalibrate the thermostats
Object.keys(this.mapping).forEach(
sensorId => this.mapping[sensorId].forEach(
thermostatName => {
mqtt.onMessage(`${this.baseTopic}/${thermostatName}/set`, JSON.stringify({calibrate: "calibrate"}));
logger.info(`Calibrated ${thermostatName}`);
}
)
)
eventBus.on('stateChange', this.onStateChange.bind(this), this.constructor.name);
logger.info(`Loaded ${this.constructor.name}`);
}
async onStateChange(data) {
const { entity, update } = data;
if (!Object.keys(this.mapping).includes(entity.ID)) { // check if Temperature Sensor
return
}
const { temperature } = update;
if (temperature === undefined) { // no temperature update
return
}
// set new temperature value to thermostats
this.mapping[entity.ID].forEach(
thermostatName => {
this.mqtt.onMessage(`${this.baseTopic}/${thermostatName}/set`, JSON.stringify({ sensor_temp: temperature }));
this.logger.info(`The sensor_temp of ${thermostatName} was set to ${temperature}`);
}
)
}
async onMQTTMessage(topic, message) {

async stop() {
this.eventBus.removeListeners(this.constructor.name);

Alternatively, you could also try to reduce the reporting frequency of the external sensor. |

When clicking a device in the web UI, there is a tab called "reporting". You can configure the reporting, but make sure to do it when your sensor is active (e.g. just sent a message, or press some button).

I was wondering if anyone is using the Xiaomi SRTS-A01 thermostat with an external temperature sensor. It is stated that this is supported by the device, but not sure how to implement it through Z2M. My main question is how to inform the device about the external temperature. Is it perhaps the away_preset_temperature the way to do it? Or perhaps this feature is not yet supported?
