Need help with temperature sensors with Philips Hue Bridge & Google Assistant

Hi ! I’m a noob at home automation so far, but I’ll looking for a temperature sensor that could work with my Google Assistant when i say “What’s the temperature inside?” and the google Assistant would reply “It is XX degrees inside”. Nothing too complicated.

But i’m struggling to find a temperature sensor that is cheap (less than 50$, ideally close to 20$) and that works with Google Home without having to buy an extra bridge or hub.
I like the Xiaomi Aqara Temperature sensors, is there a way to connect it to my Philips Hue Bridge so I don’t have to buy a Xiaomi bridge ?

Do you guys have recommendations for temperature sensors that would connect to the Philips Hue bridge for this purpose. (The Motion sensor for Philips hue is out of the picture, it’s way too expensive for me and apparently I can’t use Google voice commands to read it’s temperature data?)

Thanks :slight_smile:

EDIT : The Shelly H&T Humidity and Temperature Sensor seems to be a good match for my setup. Its battery opperated and works over Wi-Fi so no need for a bridge, and it has Google Assistant commands.

The Philips Hue Hub is designed to work with other Philips Hue devices and a few (very few) non-Philips lights. If you want broad compatibility with ZigBee-based temperature sensors, you will need to replace the Hue Hub with an ‘open’ Zigbee coordinator.

I bought those Xiaomi Mijia sensors (LYWSD03MMC): https://fr.aliexpress.com/item/4000406818501.html?spm=a2g0s.9042311.0.0.50756c37hFcFIz

Paid 12€ for 4 of them.

They work great with BLE Monitor (GitHub - custom-components/ble_monitor: Passively monitors BLE messages from Xiaomi Mijia BLE MiBeacon, Qingping, ATC, Xiaomi Scale, Kegtron and Thermoplus sensors), which is in HACS, using the bluetooth capabilities of an older RPI3

Is there any way to fiddle with the hue bridge to “unlock” it to other zigbee devices ?

That looks very interesting indeed. What hardware does the BLE setup need ? Do I need to buy extra hardware to make it work ?

Google search can answer that (no).

You need a bluetooth adapter supporting BLE.
As I said, a RPI 3B+ or 4 do for sure. It depends on what you run HA…

Check the integration github page for details.

Interesting. Did you use the Pi3 as your main home assistant server or as a bluetooth proxy for another server? I’m really interested in the second option as although overpowered vs an ESP based bluetooth proxy, it’s just sitting there collecting dust.
