Oregon Scientific THN132N / TFA D-97877 Temp sensors

Just got my new Homey Pro - trying to setup my devices on it.

Been trying to Add:-

Oregon Scientific THN132N / TFA D-97877 Temp sensors

I have a dozen around the house.

I have tried Add using the :-

Oregon App THN132N - sat 10cm from Homey - (shows up in my RFXCom receiver)
RFXCOM App
Wireless Weather Sensors

All of which immediately declare ‘No new devices have been found’ instantly.

I can see the THN132N ‘pinging’ out every ~60 seconds

I can see all the sensors ‘pinging’ on my RFXCOM but none are detectable by Homey.

Any ideas or suggestions on how to get these working?

These are a show stopper - I have the TFAs in the Fridge and Freezers and need to keep monitoring them.

Well, I do have an Oregon and my experience is that the 433mhz has NO RANGE whatsoever! Glue your sensors to Homey, maybe its close enough.

Ok thanks, much appreciated.

With this and not being able to control my ZWave Heating/Hot Water it moves the dial to does not compute.

I hold Homey in really high regard and think it is a fantastic product with extremely excellent interface and attention to detail - the closest thing I have seen to Appliance based HA!!

But too costly for me to re-engineer the whole heating/hot water systems.
