Having trouble finding individual battery cell I.D.s in Ethos

[Minimoa-2]

I recently purchased a Frsky Tandem X20 and love it, but I'm having some programming transition issues going from OpenTX to Ethos. One of them is that I had set up some warning triggers in OpenTX when the lowest voltage cell in my LiPo battery pack got below a threshold value. I used a Painless360 Youtube video to help me with that, and it was a cinch. However, after looking at the Ethos manual and going through the Telemetry screens in Ethos, I'm unable to figure out how to identify cel1, cel2, etc., and - most of all - lcel (lowest cell in the pack).
Has anyone had success with this, or know of a good instructional video covering that?
Thanks,
Mark

Are using a FLVS plugged in the balance connector of the battery.

Yes I am. I can see the total battery voltage just fine, but I can't figure out how to get the individual cell voltages and calculate the lowest cell. The link below shows a youtube video on how to do this under OpenTX. It's simple and works great. I can't figure out how to do it under Ethos.

Thanks,

Go to Zavionix at Github and down load the Zavionics Lua script. https://github.com/i3dm/Zavionix

I checked out the preconfigured widgets on Zavionics - thanks!
I did find the answer to setting this up the old fashioned way: The "press and hold down" gotcha got me! I didn't realize that if you press and hold down "LiPo" it would present you with a list of sub-functions, including the individual cells as well as the lowest cell. I checked the box for low cell and I'm back in business!

@Minimoa-2 The "hamburger" icon, 3 horizontal lines shown below on Weight/Rates and Differential, indicates a pop-up menu. Anytime you see one, you should give it a long press to see what options are available.

Adding some additional info as I was going through this today. I rely heavily on the Lipo Sensor info with OpenTX, now starting with EthOS. To announce lowest cell, add a line to Play Value to your Special Function. Choose the lipo sensor and return to save that. Press and hold on the line that says "Lipo" (name of sensor) and eventually a menu comes up with values including LOWEST. YAY! Now I need to figure out how to use that value in a Logical Switch but hey, one thing at a time

@johnfv Thanks so much, it was killing me trying to find the lipo individual cell source. Just having to hold down on the touch screen for a few seconds on source line, lipo.
