OpenTX 2.1 & FrSky FLVSS Individual Cell Voltages

Post by quadfather »

One of these moments where I doubt myself. I could swear that the FLVSS showed individual cell voltages in the telemetry screen when I tested one of the nightly builds. That doesn't seem to be the case anymore with the release build. All I'm seeing is combined cell voltage. Am I imaging things?

OpenTX 2.1 release on Taranis
FrSky X8R
FrSky FLVSS
Generic 3-cell LiPo

Thanks in advance for any pointers.

EDIT: Remembered how I did it. See my answer below.

I saw that it was disappear as well.
I found that I can define it myself, additional 6 lines (one for each cell, 6 in my case) in the telemetry lines, and then place them into a telemetry screen.

Anyone have a different way?

No that's the way. It typically isn't of much use to see all cells when you can show both lowest and delta.

Ha! I remember now. Cell examples for FLVSS below.

Add a new sensor.

To display the lowest cell voltage set it up like this
Type: Calculated
Formula: Cell
Cell Sensor: Cels
Cell Index: Lowest

To display the voltage difference between the highest and lowest cells set it up like this
Type: Calculated
Formula: Cell
Cell Sensor: Cels
Cell Index: Delta

Cell Index is the key here. You can also show individual cell voltages. Simply add a sensor for each cell of your battery, configure as above and select the cell number in the Cell Index.

Hope it helps.

The lowest cell is indicated correctly on the telemetry screen, BUT the voice announced value is not accurate??

If your custom sensor is called "lowc" I suppose you just have to add a special function like "play value" "lowc" ? I play the value of lipo consumption from VFAS this way, so it should also work for FLVSS.
