I am presenting my new unified BLE Sensors app.
Currently this app supports:
ThermoBeacons
TempPro Devices
There are more devices to come. The TempPro support is generic so if your device uses the same protocol as other already supported models your chances are high that it will be supported too.
Here is the test version:
For feedback, I’m unable to connect both TP351S and TP357S.
The other app (Thermpro app homey) TP357S can be connected.
Did you try to connect multiple times? Was the device not listed or it just could not be added? Can you do a diagnostics report?
I implemented a fix to ease the strict model check in the ThermoPro driver. I hope it works now for you. Due to the lack of alternative models my testing capabilities are a bit limited. I ordered a TP351S for testing but until it arrives I am a bit limited. 
Yes, now i can add both the TP351S and TP357S. i’m going to check if everthing works oke!
Great work!!
