Yesterday my two ordered Chinese battery monitoring stuff arrived: each 18.50 euro.

Why I had to allow the "correct location" to be used by the app on my phone is still a mystery for me, only Mao knows.

I only tested the battery voltage, not the other possibilities (cranking test, charging test).
My car didn't move now for nearly two weeks for different non-technical reasons.
This is the picture of my battery status before installing the devices:

Of course, key in, ignition on.
Here some screenshots from my phone, after installing:

I can input myself different names, but the devices are identified by different serial numbers.
The device also saves in it's internal memory the data of a longer period, 35 days according to the app manual.
When you move within the reach of your car this data is synchronized to your phone.
This is the overnight data of the main battery (similar for the auxiliary battery), I didn't open the doors of my car, not one time:

There is also a nice slider to measure voltage peaks or drops at certain moments, first image of the main battery, second of the auxiliary battery, while installing, testing, etc. and opening and closing doors. First image is from the Main Battery, second from the auxiliary battery:

Pïty that on this chart the battery name isn't mentioned!
Evaluation:
- Device works
- China is watching me
- battery voltage quite stable, no sensitive drop in about 24h.
- state of charge seems to be (in %) the same as what the Grenadier makes of it!
- Voltage measurement seems to correspond to the Grenadier (see the 12.1 Volt on the info screen, and the 12.13 lowest value of the main battery while installing)
Next steps:
- crank test
- charging test (with the device function)
- drive test
- some bastards on this forum made me spend more money. I bought a CTEK MXS 5.0 battery charger, arrived today: charge test with the CTEK.
I continue to play around without driving, but I am longing to finally do some travelling again early September, after delaying it three times now!
