Ruuvi tag in sauna

Patraff · July 9, 2024, 10:10am

Hi,
System - Core 2024.7.1 - Supervisor 2024.06.2 - Operating System 12.4 on Intel NUC

In searching for a better device to monitor temp and humidity in my sauna I bought a Ruuvi tag.
My current setup has a shelly plusHT. The temperature is pretty consistent but the humidity values are way off. I contacted Shelly who told me the device should not even be in my sauna (hoping that the battery doesn’t explode some day).
So I setup the Ruuvi tag using the app on my phone - gotta be one of the most seamless setups I have done on any device. Anyway put the device in the sauna and found that HA doesn’t see my device. Further reading indicates that my system being an Intel NUC doesn’t do bluetooth very well.
So - I thought i would pair the Ruuvi with the app on a sauna controller device (galaxy tab) that is just outside the sauna and allows control througha HA dashboard of other components being ice bath, lighting etc. The Galaxy reads the data but for the life of me I can’t work out how to get that across to HA.

Any ideas?

Do you have more products from Shelly? Plus or Pro
You can use these in HA as a BT gateway

apreick,
I don’t have any Shelly’s nearby that would do the job. I had considered buying a bluetooth dongle and running an extension usb cable so that the dongle is the other side of the sauna wall. The wall has lots of insulation with foil backing inside.
Would love it if I could hard wire the ruuvi to my system rather than rely on bluetooth.

Actually a different topic, but which Ruuvi tag do you have? Range is apparently -40 ºC to +85 ºC, I think.

How warm does your sauna get?

Instead of a BT dongle, I would buy a Shelly Mini Gen3, for example, to test this. If that doesn’t work, I’m sure you’ll find another task for it

Sauna gets around 80 or so. The higher temp is only achievable with a ‘special’ battery. When I tried to source one of these in Australia I couldn’t find a supplier.
Will look at the Shelly mini Gen3. Got about ten shellys sitting around looking for projects.
I have the RuuviTag 10BE. Would be great if I could just display the ruuvi app screen within my HA dashboard for my sauna. That won’t allow me to run automations though without having a sensor value.

OK so I’ve got the Shelly mini gen3. I am really struggling here. I can see the shelly and have configured it as a bluetooth gateway and set the mqtt as on. I am now running around in circles trying to make it all show as a sensor that I can display on my sauna dashboard.
I have absolutley zero experience with manually setting mqtt in config. Do I need to do that? I can see a regular publish of data in diagnostics on the shelly as below - how do I make that usable?

I don‘t have a ruuvi

But here

and

You have activate the BLU in Homeassistant by the Shelly?

Hi,
yeah i followed all that and still had dropout issues. Like below i would have the ruuvi just dissapear from providing data for hours at a time.

I have shut down bluetooth on my tablet device that is outside the sauna which shows a sauna dashboard from HA through fully kiosk. Maybe that was having some form of impact?

I tried settings as set out in a guide by Stefan K - using ruuvi tag to send data through mqtt. Not quite sure if i should have done this. It includes a script (way beyond my skill level to understand).

Anyway the shelly is set in bluetooth as a gateway, it is located less than 1m from the ruuvi tag. There are two walls and some foil backed insulation within the walls but still the connection should be fine - image showing signal strength.

Will see how it goes over the next couple of days.

Hi
so the ruuvi was going good for about a week. Then I get this weird thing - the ruuvi shows the temperature at the correct setting but was is reported is not. See image

The temperature is correct at 64 degrees but the device states 24. ???
What goes on here?
