@smurf12345 Good stuff! Try sending this frame to initialize the Bus, while active charging and see if wakes up the ECU. Let us know if it works. {"bus":"0","type":"tx","frame":[{"id":2015,"dlc":8,"rtr":false,"extd":false,"data":[2,1,0,170,170,170,170,170]}]} |

Hi All:
I just received my WiCAN and hope to be able to pull battery back information along with other data points. So far I was able to pull the mode 1 battery pack remaining information using the examples in the documentation. I'm using Node-Red to collect this information in Home Assistant.
I've set the WiCAN sleep mode to go to sleep when voltage is below 13volts. This way as soon as the car is put in run/start, the WiCAN wakes up and starts pulling information. I was hoping the ECU would wake up while plugged in and active charging was happing when the car was off, but looks like the ECU stays asleep.
I would love to see some people's examples of pulling Mode 22 battery information if it is even possible. I have found some information out there on my car (Pacifica Hybrid Plugin) specific PIDs, but haven't made sense of it yet.
Here is what I have so far using Mode 1. I maybe getting multiple answers back from different modules with all the same information, so I may need to filter the receive message a bit more.
