RS232 data

Ok so would you agree that the battery is 24.8v and the PV is 26.3v

As for wattage I will have to look into that. What do you think the kid was doing for watts at the time of that stamp?

And yes 6 will be no good with no BTS, 8&9 also will be default with no WBjr

As for 10 I am trying to get a list of these now

Our network switch says we are drawing on average 1.3 amps at 27.2 volts so I would expect around 35.36 watts.

@rayclark
I'd suggest you to look at my previous repository containing some data decoding attempts:
https://github.com/Nomad1/KIDStats

P.S. Note that there is firmware version lurking somewhere that contains complete garbage instead of data. I don't remember it's number, it could be 1863 or something alike.

Any more info on this? I'm preparing to do the same - get data out of the Kid.

Some of my customers would like to have this data available to look at on their tablets or phones.

Usually I use a controller that broadcast it via WiFi and it looks like a web page.

Some controllers use phone applications - not excited about those but understand why.

Is there an easy way to buy / connect - get this working wirelessly?

It is for a nominal 48 volt / LiFe based system.

Thanks

For the Kid there is no easy way to get the data from it like you are asking about.

Thank you.

Any of the other models capable of this - or via an add on device?

For instance in this thread, the OP was working on a way to retrieve the data - so I assume that it could be available from there.

yes there is or was a way to get the data out of the kid, though if I remember correctly one of the firmware updates broke the data out. It may have been fixed but I haven't messed with it. You only get some basic data out like volts, amps , etc . There are details on the forums here how to make serial connections to it .
I guess you could program a an esp32 to get the data and make it into mqtt , which then could be read by other programs . A programmer could get the esp32 to serve up a webpage with the data too. First thing to do would be to connect up serial and use terminal program on computer to verify that the data output is there.
