I installed the the ELM327 for my 2017 Volt days ago. When can I expect to see the battery report?
Where are the instructions for using MyGreenVolt?

New user. When can I expect to see the battery report?

Such documentation as I've found is here: More
There are tabs, or a pulldown menu of tabs, depending on your screen orientation. Tapping "batt cell" (I think that's it) will switch to the cell voltage display. If it says "PURCHASE" in the corner, you're looking at a demo screen and need to buy the upgrade for a dollar. Cell voltages change A LOT so only expect consistency/reliability when the car is on, but parked for a minute or two, and engine has turned itself off. Fresh off a charger will show you how well the balancing has worked (cells should be very close together in the min/max read out at the bottom, but will hide weak cells from you. Doing a reading when the battery has been discharged and the car has switched to engine at least once will show weak cells if there are any, and you'll see a bigger deviation between the min and max in mV.

I did buy the app. And it's been a few days and the Batt Cell tab is still blank.
"cells should be very close together in the min/max read out at the bottom" - Please define "very close""?

I believe that the maximum deviation between the maximum and minimum voltages is 121 mV. What you should do is develop a history of the max/min cell voltages to determine that no particular cells are showing up consistently. If they are, then you have found your potentially weak cell(s). You can make a plan regarding your Volt based on that info.
did you buy the app or make the in-app purchase to see the batt cell voltages?
it should work immediately, does any other data display on the other tabs?

Everything, every tab, every page is all zero. Except the Bluetooth tab: "Already connected to OBDII"
So you did not do the in-app upgrade purchase to enable the cell read-out?

You didn't specify your phone system ... Google Android or Apple iOS but I'm guessing Apple now since it looks like you pay upfront for that. Android is a free app and $1 for cell details.
Apple iOS: MyGreenVoltConnect
Google Android: MyGreenVolt - Apps on Google Play
This site had an email contact. See "Support" section: MyGreenVolt

I appreciate your assistance.
I clicked on the "Purchase" button on the app on my Android phone. Was I supposed to do it differently?
That's the right thing to do, but that was the first time you've said that's what you did in a way that was clear about that you did this particular thing. So, app installed, cell readout purchased. Car on? Reader dongle plugged into OBD port, reader dongle paired with app? App showing data on the main dashboard?
If your android version of the mygreenvolt app is connected to the OBD device, the app’s Dashboard display should show you a good deal of information about your Volt. If the Dashboard is blank, you have a connection problem.
As for the individual cell voltage reading page, my understanding is you need to click on Purchase to get a display of the real individual cell voltages, and, I understand, you need to be in wi-fi range to do that. The wi-fi connection enables the app to confirm you have paid the $1 for the app. If the app can’t confirm you have paid for the app, it won’t scan for a reading.

All yes, but all of the data on the app dashboard is zero.

What brand of OBDII do you have?

I have the same problems. The first OBDII device I bought will pair OK but I don't get any valid readings. The new one I just bought (small ELM327) won't pair.
I paid the $.99 for the battery cell function. My Volt is a 2017.
I plug the reader in, start the car, and pair the device to my Android phone.
I did get some readings after I drove the car the other day. But since then nothing. Does it only work after you've driven x miles?
That doesn't actually tell us much. EM327 is the name of a microcontroller chip that does OBD-to-RS232 transcoding, but it's in a lot of OBD readers, some of which support the right messages to work correctly with MGV, and some of which don't. As an example, here's a list of brands I found while asking for "ELM327" on Amazon:
FORScan
ODBATOR
BAFX Products
Taotao
ODBMonster
AUCARAUTO
SCCJGL
Grafken
SOOLOON
Fanlynk
WashingLee
OBDLink MX+
VEEPeak
MeStart
VGate
BlueDriver
Foxwell
aoonav
LAUNCH Creader
Konnwei
Autosion
At least six of those are obvious attempts to pretend that they're the VEEPeak one (being identically shaped and colored), four look like pretender FORScans (shape and label pattern), and there's one pretender OBDLink. We especially don't know how well the obvious pretenders are, because if they're willing to rip off design choices and sell for $8 instead of $17 (much less than $140 that the app-author-recommended OBDLink MX+), who knows what other shortcuts were taken?

By brand, I meant the name of the device that uses the ELM327 chip. As an example, I bought the Vgate iCar II Bluetooth 3.0 OBDII that works with MyGreenVolt app.

So one of the VEEPeak Bluetooth/Android ones will work to your knowledge? I'll take
one more chance for my third one...

Good points above by hellsop and jbakerjonathan
I would look for free returns (in case it doesn't work) ... $20-$30 range ... 5000+ reviews w/4+ starts ...
3 examples
I'm using a more expensive one that handles large amounts of data for my Tesla (and works my our Volts)

Thanks- This is the one I bought on a recommendation from the Volt forum on Facebook.
So, any of the three you listed above should work with then GmVolt app?
