For everyone following along, I'm going to create a new thread about the code I've written to check the state of the FCSP. Right now that's the only valuable info I can gleam, but as we find more ways to use it, I'll update the code.

I got busy with work and haven’t had a chance to hook up my serial terminal server, but this is great intel, let me do some research on this Linux distribution. Looks like it is from Texas Instruments, so maybe they have some default passwords we can try.

Nothing in the current API related to OCPP, which would have been a huge win if it existed. I've finally got my Raspberry Pi Zero serial setup complete, so I can start probing from the comfort of my office instead of going out to the hot garage. :) If I can figure out how to get into the unit...

I've got some sample code to pull what little data is available from the API directly on the FCSP, but I haven't had time to clean it up. I'll try and do that tomorrow and post it on github. Here is where I left it off, it can detect state changes now, but I don't see any way to tell what...

I was thinking a full breaker off power cycle. I just remember I do have a spare Raspberry Pi Zero W that I can turn into a wifi rs232 node. If I have some time tomorrow I may play with that and see if I can match what you are seeing.

The next thing to try is hook up to that uart and power cycle the FCSP and see if it gives us any clues during boot up I don’t have a usb serial adapter handy or I would, but I’ll see if I can get one to start playing with this.

Ooh, that EVSE prompt looks very promising. Have you tried any logins on it. Here are a few to start with: Common Default Credentials to Try Most Common Siemens Defaults: • Username: admin / Password: admin • Username: root / Password: admin • Username: root / Password...

Unless I can find a way into the Linux is running on this thing, I’m not sure there is much more to see. I can’t see charging rates through any of the exposed APi’s, just that status message I showed earlier. How valuable would it be for people to have access to just that piece (along with the...

Yup, already working to enumerate all of those. So far many are just returning status codes or are just POST methods (probably to update settings). Still need to dig more, but so far haven't found the right combo to get what I want. Once I get the test code to pull all the values in one shot...

Making some progress: # python examples/simple_inverter_example.py ? Connecting to FCSP device at 192.168.1.197... ✅ Successfully connected and authenticated! ? Retrieving inverter information... ? Inverter Information: ================================================== ? Inverter 1...

The more I think about it, I wonder if the devkey is the same for everyone. Once I get this software written, I may need a few volunteers that are a bit IT savvy to help me check their devkey's. If its the same for everyone, then I may just hardcode this for now (but an update to their...

Right now you have to use a MITM solution to get the developer key, which you can then use to get the Bearer token. I'm writing up some Python code that will show how to do all of this except getting that developer key (although I'm gonna see if there is any way to get programmatically as well).

Welp, I have some good news. I'm working on some software to make this a bit easier, but the hard part was getting the developer key: curl https://192.168.1.197/api/v1/inverterinfo \ -H "Authorization: Bearer <THISISSECRET>" \ -k [{"vendor":"Supreme Electronics","name":"inverter...

We had enumerated that before in another post, but it led no where at that time. Here is something new I just found that might be worth looking into, especially the modbus piece. https://cert-portal.siemens.com/productcert/html/ssa-556937.html

A while back, I tried different ways to access through ssh, but didn’t have any luck. I figured if I could get access to the underlying Linux instance maybe I could pull data straight from dev registers.

Have you read anything about the difference between the Defenders and the Primacy? I also worry that some results are skewed because of the Lariat vs Platinum (20 vs 22) size differences, but maybe I'm overthinking that part.

I've looked at those BFG's (and the Toyo Open Coutry) as well, but like you I worry about increased in noise. As an alternative to the Grabber's, does anyone know what the differences are between the Michelin PRIMACY LTX and the Michelin DEFENDER LTX M/S 2 as far as ride quality? The more I...

I need to replace my 2022 tires, and I haven't been that happy with the General's (light vibrations at highway speeds, wasn't suspension related). I'm not really in need of off-road, but I'm not opposed to them either. I want great around town and highway driving, plus good wet performance. Snow...

Just got mine today (25.2.1.6.5) and it was much quicker than most updates. Super happy I can now turn of WAL. I like the idea, but I just want to control it.

We call it a Guess-O-Meter for a reason. Try resetting your driving stats and see what it does. There are a ton of factors that go into this, but most of us just watch miles per kilowatt-hour (mi/kWh), to see how it’s performing. During the winter I will get anywhere between 1.5-1.8 and during...
