BMS cell monitor

Hello.

Just received the OVMS. Got a 453 EQ.

All working, but the BMS cell monitor doesnt show data. Normal?

Also, the two gauges on the top right on the dashboard doesnt move. Also expectable?

obd can1 req dev 79B 7BB 2141
obd can1 req dev 79B 7BB 2142

config list xsq

and post the output

Any thoughts why nothing

Any thoughts why nothing shows up on "BMS cell monitor"?

no, but i have made a test Firmware with some changes. Can you test it pls?
go to Firmware: Flash from Web. Http URL: ovms.dimitrie.eu/firmware/ota/v3.1/main/ovms3.bin

let me know if it works

ptgomes

can you send me the shell log output when you you set the log level to verbose.

in shell type: log level verbose

then make ignition on

I also have a ForTwo EQ and want to read individual cell voltages etc.  Did you have any luck to get so far ?

I get data as I said, but can't interpret it. It seems there's one cell that deviates.

You get two of 96 pairs of data. If you combine four hex numbers and convert it into binary you will get a number that is very similat to a voltage readings:

0f a6 = 0fa6 = 4006 = 4.006V 
0f 92 = 0f92 = 3986 = 3.986V
