Last week I came across a deal on a small thermometer with display and Bluetooth access for under $10 so I had to give it a try. The fact that the data is available via bluetooth instead of via a web service was a major selling point for me. I am hoping to be able to to log the data via a Raspberry Pi4.

I installed the Govee Home app on my iPhone and it was able to find the device, communicate with it, and pull both current and accumulated data.


When I attempted to find it from my Pi4 it was much more difficult. I live in an apartment with units all around. I’m not just dealing with my own devices that may be visible, but my neighbors as well.
I managed to find the device using linux command line tools, but was not able to successfully connect. A friend suggested BLE Scanner 4.0 for my iPhone for discovering the details, and it was at least able to confirm what I should be looking for using the linux command line tools. I still had timeout issues with the iPhone app, but at least was able to confirm that I could connect to the device and retrieve GUID information.








This is my first time attempting to gather data from a Bluetooth device. I’m still in the research and test phase. I’m listing a bunch of the URLS I’ve found that have been helpful.

From the command line on my Pi4 I already had the tools installed to try several Bluetooth commands. I believe they were installed as part of the bluez package. The first two commands below get details on the Raspberry Pi Bluetooth hardware, then the hcitool lescan command produced a lot of devices, and I found the line referencing the GVH5075 so I could use the address in further commands.

Another command that I attempted before I used the hcitool command was the bluetoothctl command. It scrolls a lot of data, but now that I have an idea what I’m looking at, I may be able to see announcement data from the thermometer periodically in the stream by filtering just to see the data coming from the MAC address.
