GWM ORA battery health TX, RX and expression

[holger1414]

Hi!

Do you happen to have any info on that sensor?
Thank you very much for your project!

Hey @holger1414 Please try the new beta version, this will make it easier for you to get the battery SoC.

With this firmware you can setup WiCAN to publish the SoC without the TX frame. wican-fw_v310beta_hv300.zip

Here how to set it up, Frist you need to update the device, just extract the bin file and update

Go to Automate tab, and fill in these parameters, click the "store" button then reboot the device. after reboot when it connects it will start publishing the soc to topic: log_soc

Name: SoC
PID: 220308
Expression: [B4:B5]/10
Period: 1000
Send_to: log_soc

Hi! Thanks for the quick response! However, I am asking about battery HEALTH :) I have SoC and mileage working very well.

Sorry I assumed you wanted the SoC.

Does carscanner or any other app read the health?

[holger1414]

My bad!
I was replying via email and included screenshot, but it did not make it to discussion :)

{"bus":"0","type":"rx","ts":2305,"frame":[{"id":1995,"dlc":8,"rtr":false,"extd":false,"data":[5,98,32,81,3,165,204,204]}]}
Car scanner value 93,3%

This value has not changed yet, so I can not provide additional data :/

[meatpiHQ]

what is the TX frame?

This expression should work, ((B4*256)+B5)/10

[holger1414]

Amazing!
It worked!
So the expression for SoC and Healt are the same. Was not expecting that :)

Thank you!!

BTW TX frame is
{ "bus": "0", "type": "tx", "ts": 18461, "frame": [{ "id": 1931, "dlc": 8, "rtr": false, "extd": false, "data": [3, 34, 32, 81, 170, 170, 170, 170]}]}
