Since we have a new born the temp of a room is becoming more of a subject.
So i've used the Phillips Hue Sensors with their baked in temp sensor.
Sometimes it can take 15-20 minutes before updating, that is way too long.

I woule like it around 5 minutes.

Currently everything is Zigbee2MQTT and am looking for a seperate temp sensor that is quite accurate with that update time frame.

Are there any recomendations, personally i was looking at Aqara Temperature And Humidity Sensor T1 but wouldnt mind a display too so I dont always have to open Home assisant

Think the Aqara only updates if it sees a change greater than .5 or 1 degree, I think most operate that way to save power. Another option is an Esp32 with a temp sensors they poll around every 2 minutes depending on the sensor you may need to set an offset to correct the temp value. Can’t speak to sensors with a display as I have dashboards around the house

@shut carbon many Zigbee temp/humidity sensors can be adjusted to refresh more often, in Reporting settings

#

I tested this and SONOFF reports every minute

#

press button on device, and than click apply from reporting to modify

#

#

This is currently set to 30 sec and it works, if there is temperature change

#

model is SNZB-02LD

#

It will drain battery faster

The xiaomi ble temperature and humidity sensor with the pvvx firmware https://pvvx.github.io/ATC_MiThermometer/TelinkMiFlasher.html is what I use all around the house. Updates every 10 seconds and is very accurate.

#

You need to have Bluetooth though, for example via a Bluetooth proxy

Yes, I use the Xiaomi and it's great

Thanks for the answers, bluetooth aint gonna be a option since I need to make sure it everywere available without more proxy's
@spiral root Sounds good, just found out that the motion sensor only updates when where is motion and not on degrees.
Are you talking about the SNZB-02D

What's the hardware you use with HA?

#

I use a RPi4 and the Bluetooth is integrated, no extra hardware needed

Got a NUC, good chance it has bluetooth but doubt it would have the range

Well, you'll be surprised, and you can also create some Bluetooth proxy devices with ESP32 and ESPHome in a few minutes and cover your home ant the neighbors home if needed 😉

Wouldnt that be more battery's to monitor and change? tbh i would like Bluetooth for some sort of presence detection

#

My idea would have been it connects to the closest which will tell me who is in what room

dire vortex Well, you'll be surprised, and you can also create some Bluetooth proxy devices ...

Still gotta dive into ESP32

No, no, you can use a cheap cellphone charger

@shut carbon I tried with SNZB-02LD that is for outside temperature with probe, will try later when get home with SNZB-02D since I have that as well

spiral root Nov 20, 2025, 11:19 PM

yes, same setting can be done for SNZB-02D
