I am running a heater automation off of a nearby door sensor that also gives me temperature data. Is there a way to update this temperature reading to a more frequent interval so the automation doesn’t lag the real world temperature change?
If the Aqara door sensor that you are using is integrated with Home Assistant using the Aqara integration, you may be able to adjust the update interval for the temperature data by configuring the scan_interval parameter in the integration’s configuration.
The scan_interval parameter determines how often the integration will poll the sensor for updated data. You can set this parameter to a lower value to increase the update frequency for the temperature data.
Here is an example configuration that sets the scan_interval to 30 seconds:
aqara:
gateways:
- ip: 192.168.1.100
key: abcdefghijklmnop
scan_interval: 30
Note that setting the scan_interval to a lower value may increase the load on your network and on the sensor itself, so you should carefully consider the trade-off between update frequency and performance.
You can’t scan the door sensor. The sensor sleeps, doesn’t listen for radio queries, and only wakes when it has a state change to report. All the integration scan is going to do is query the Aqara hub which in turn will just report the last value sent by the sensor.
I wouldn’t be surprised if the temp sensor isn’t even exposed in the Aqara app. ZHA and z2m expost it because they can. It’s the temp of the device/processor, not ambient temp. In practice it’s fine for relative changes to the ambient temp, just don’t expect it to be extemely accurate compared to something a stand alone temp sensor.
I don’t know of any way to change the interval. It’s possible the device might honor some of the zigbee report interval options, but I sort of doubt it. Likely would be better served withe the real temp/humidity sensor.
Good to know…In this case, it may be more pertinent to use a different sensor that is specifically designed to provide more accurate and frequent temperature readings.
It’s worth noting that increasing the frequency at which your sensor provides temperature readings may not necessarily result in a more accurate representation of the real-world temperature, as the sensor may not be able to keep up with rapid changes in temperature.
In order to get the most accurate temperature readings possible, you may want to consider using multiple sensors and averaging the readings from each of them to get a more accurate representation of the temperature.
Makes sense. I think you are mostly correct, but I did place ice on the sensor and it eventually updated the much cooler temperature WITHOUT changing the binary state of the sensor. There is some kind of update period but it may be hard-coded in the circuitry or firmware.
Did you find out what is the default update of the temperature sensor?? Good to know for reference. I think is 60mins.
