Ok I tried the build and indeed it does see that the sensor is there now but reports it as being a temperature sensor. Bizarrely enough if I hold the sensor in my hand the reported temperature goes up so Flysky must be sharing circuitry between the altitude and temperature sensors but how I have no idea. Is there any way of getting it to detect it correctly as an altitude variometer.
Thanks

Test build is updated ( c0b217e ).
Was the displayed temperature anywhere close to the actual temp?

The altitude is displayed AGL. Long press on UP at the top of the telemetry test page will reset it to 0.

The A7105 radio chip does not provide a software means for detecting that a new receive packet has arrived. Deviation reads the receive buffer on every protocol cycle. Likely the temp and alt telemetry stays active because the last telemetry packet contained that data, and it continues to be read after the receiver is turned off.

So the accuracy seems to have gone out of both the temperature (by 2 degrees more than actual) and the altitude, which is now recording less than actual and keeps flopping about. Before the scale factor was out it was very accurate i.e. 0.01 was very close to 1m 0.02 was very close to 2m.
The good news is that now when I switch off the receiver all the fields go black whereas previously temp and alt were staying non-inverted.
I really appreciate your work on this and hope my feedback is helpful.
Just in way of some further experimentation, I went back to the previous build and in fact the temp and ALT fields do go inverted (black) they just take a bit longer. Actually I can live with the multiplication factor being out.

Just a note, a long press on the UP in the Telemetry screen does not seem to reset to 0 it just exits the telemetry screen.
Now I just need to do the Devo 10 voice mod

But the reset works on my 10. If this procedure doesn't work for you please post a video of your tx.
