Need reco's for temperature sensors

Hardware
1

Greetings all,

I need the assistance of the Home Assistant brain trust.

I’ve got a Thermadore range top in the house we had built a couple of years ago. There is a ZLine Range Hood over the top.

The range works well, but the “brilliant” designers didn’t see fit to provide a positive indication that a fire was on.

Yea, I get it, ordinarily this isn’t an issue. The problem is the knobs have a grab that is virtually parallel, and the full low position looks a LOT like off. Way too much.

I’ve gone old school and put some colored tape to indicate, but even that is not proving to be sufficient. Three times now, we have left a low fire on the stove for extended periods.

I had some SONOFF SNZB-02 ZigBee Indoor Temperature sensors, so I applied one inside the hood and one outside the hood to see if I could read a temperature difference so to write an automation that would send an alert if the stove was on for any length of time.

The experiment worked wonderfully. Even with one burner at full low, the Delta-T was over 10F very quickly.

Unfortunately, the Sonoff’s turned out to be completely unreliable. They are constantly wanting to be re-paired with my HA Yellow.

So, I’m looking for reco’s on a reliable, long life temperature sensor to use in this application.

Thank you for your wisdom and advice!

I’ve had a few Zigbee sensors for temperature that are accurate but then go offline. The Govee BLE ones are awesome though. Accurate, update quickly, battery lasts a long time, and work in a fridge or freezer. When we lost power for a few days I could even read them in the Govee app to watch as my food thawed and eventually went bad.

H’mmm.

Firstly: I don’t have a BLE device. Is there a BLE device I can plug into my HA Yellow?
Secondly: A quick (?) search doesn’t return any hardware responses to Govee BLE. Is there more info?

Thank you

I have a few esphome/Esp32 devices that act as Bluetooth relays. The ble device is “Govee Bluetooth Hygrometer Thermometer” when I search on Amazon.

Well,

Was hopeful I could find something to do BLE without soldering … :wink:

Thanks. I’ve got two BLE light bulbs and was not able to find a BLE device to talk to them with.

Would love to have a BLE device with a network connection at a reasonable price.

Doing a quick check at “The Smartest House” they have z-wave sensors available.

I’ve got a couple of their z-wave devices and they work just fine, so I’ll prolly go that route.

cheers

Ok,

Found the Govee Bluetooth Hygrometer Thermometer’s. Makes sense

They act as relays.

What do I use to originate the connection?

Sorry, but this whole BLE thing baffles me. And I don’t want my phone in the loop as I might not be in the house for the devices to talk to.

cheers

Would this work?
