4.0.1 DSM Temp telemery?

I just added a TM1100 to my DSM2 quad in order to get voltage feedback. The telemetry monitor seems to be working as well as expected - Battery & Rx voltages and temperature all display. No Rx info, as the Rx has no data port. I've set and tested the alarms for battery voltage, and they work fine, so I got what I wanted.

However, I'd also like to set an alarm for temperature. After all, it's there. But when I select Temp in the telemetry settings, I can't change the value. It's stuck at "---".

Bug? Fixed in nightlies? Any suggestions?

Thanks,
Mike

Thanks for the confirmation.

If you're running the nightly, can you tell me if more telemetry data is available for putting in display boxes on it? I'm thinking about adding altitude, but can't do it on 4.0.1.
