Cannot run this program, help is appreciated

[requiemmg]

Hi,

this is exactly what I am looking for. I have a SmartGrid enabled tumbler and washing machine and a SolarEdge inverter.

Now I'd like to make use of smartStart. I have not found a solution for home assistant.

Unfortunately, I am no too much into programming and your instructions failed me.

I try to run this on a Raspi 3B.

First I tried "go get" which told me that "get" was deprecated and I should use "install" instead. Did so, but calling the package failed with "is not in GOROOT folder".

Second I tried docker run, which gave me

WARNING: The requested image's platform (linux/amd64) does not match the detected host platform (linux/arm/v7) and no specific platform was requested
exec /mielesolar: exec format error

I'd really appreciate help in running this. Further, can I start it up automatically on the raspi's reboot?

Thanks for your time.

[requiemmg]

Okay,

now I have it installed (git clone, move to $GOROOT, go get, go build), but the parameters seem to be wrong. I have set up a config file (devices.json) and call the program but I get a "user/pass wrong" - I copypasted them from another project which uses the API and which is currently up and running...so it must be the syntax. The syntax differs which the program expects differs from the example in the readme.md. Tried both, but there must be sth wrong. Can you please tell me how to properly make a call?

Response: {"message":"username/password is invalid"}

Tried with and without "" at different places....

[IngmarStein]

Sorry, I missed the GitHub notification!

First, I've updated the installation instructions to use go install which was introduced in Go 1.17. Thanks for mentioning that.

Second, the format of the client ID (8-4-4-4-12 characters) and secret (32 characters) look correct. Your example command line has a stray mielesolar between the -client-secret and -inverter arguments. Was this just a copy & paste error?

[requiemmg]

Thanks for your reply and nevermind the missed notification!

In fact, the additional mielesolar was copied from the installation instructions and its still there.

Noticed already but I always get the failure that my credentials are wrong - while they run fine in another project (and no matter if this is running or not) MMM-Miele for MagicMirror.

I tried with and without " or '.

Would really appreciate help. And maybe you can add instructions on how to run it as a system service on a pi?

Sorry, I have not that much programming experience and none at go....thanks a lot for your work!

[IngmarStein]

The example command line in https://github.com/IngmarStein/mielesolar#3-run-mielesolar is slightly different: it passes credentials through environment variables instead of command line arguments (so that they're not visible in the process list). Maybe you can try that and check whether the environment variables contain the expected values and no special characters are interpreted by your shell?

I'm running mielesolar natively on a Synology NAS and used to run it in a Docker container before that, so those two paths are tested. I don't have a Raspi around to test a system service, but instructions for that would be a welcome contribution.

[requiemmg]

Yup, I got thru that, and I think there is some problem with the command line options. Just to be sure, I requested new credentials but Miele seems to process them manually. As my current one's work, I think it's either a problem with my syntax, with the interpretation of my syntax or maybe a bug in the code. Anyway, I am highly interested in sorting this one out.

Docker build is not for Raspi and I do not own a Synology NAS.

And sorry, I do not know how to check env variables from bash on my raspi for a specific program which runs from the command line.

What I noticed today: I just started mielesolar with user/pass/client/secret, this was already sufficient to get a 401: user/pass invorrect error :-(

./mielesolar -user 'mymail@gmail.com' -password 'password' -client-secret '12345' -client-id '91253'
2023/01/18 23:14:02 error retrieving Miele token: oauth2: cannot fetch token: 401 Unauthorized
Response: {"message":"username/password is invalid"}

(of course, my credentials have been changed, but this is what happens when I use the correct credentials). I think, first I have to go beyond this point.

I don't know what to try anymore. If you want I'll contact you on LinkedIn and we can find a way you can try it out on my raspi?

[IngmarStein]

Your client ID + client secret seem valid. If they were not, you'd get Client credentials are not valid instead of username/password is invalid.

The country selector is important - it's a necessary part for authentication. The default is de-CH (as a convenience for me), so you need to pass the location in which your account is registered, for example -vg de-DE.

Btw, the Raspberry Pi can run Docker (https://www.simplilearn.com/tutorials/docker-tutorial/raspberry-pi-docker), but a native solution may be preferred.

[requiemmg]

About docker: On a raspi, I will get an error that it is a wrong platform...

BUT...we are getting closer. Now providing -vg de-DE will authenticate correctly. Specifying the inverter's IP also works. Verbose also works. But specifying either -auto or a config file will just throw the help text. But we are getting closer.

Next step after running it from shell: running it as a service from startup. Corrently, I need to be in the programs directory.... (/usr/local/go/src/mielesolar)

[requiemmg]

Update: WORKS now from the command line (I forgot to specify an int value for "auto", but as I have 4 Miele Devices I will need to think how I will priorize them in a config file). Now I need to find out how to run in automatically on startup..

Thanks for your help! (I think the missing -vg de-DE was the problem when I finally could compile the program)

[requiemmg]

I think this looks fine now :-)

Btw, the Raspberry Pi can run Docker (https://www.simplilearn.com/tutorials/docker-tutorial/raspberry-pi-docker), but a native solution may be preferred.

Problem: I wouldn't expect your docker-image to run on a raspberry pi, as it is not (cross)compiled for arm/v7 (v6/v5/64v8) architecture, see https://hub.docker.com/r/ingmarstein/mielesolar/tags

Would you consider crosscompiling it? e.g. using docker buildx https://docs.docker.com/build/building/multi-platform/

Or add instructions on how to compile it oneself.

git clone https://github.com/IngmarStein/mielesolar.git
cd mielesolar/
sudo docker build -t mielesolar:v1 .
# modify docker-compose.yml to use selfbuild image
sed -i 's,ingmarstein/mielesolar:latest,mielesolar:v1,g' docker-compose.yml
# confirm everything went fine up to this point
sudo docker-compose up
# add credentials (save and quit with CTRL + X, confirm with Y)
nano docker-compose.yml
# test (quit using CTRL + C)
sudo docker-compose up
# run as background service (daemon mode)
sudo docker-compose up -d

At least for my raspberry pi 4 (arm v7) it looked like everything went smooth. Unfortunately i have no miele devices to test it.

@requiemmg well done and welcome user number 2 :) Looks like you're up and running now. Let me know if you managed to get a smart start triggered. It would be a great addition to build a Debian Package for Raspian and host that somewhere.

@Setcover you're right the image is currently only available for linux/amd64. Shouldn't be a big deal to cross-compile it for armv7. I might have a look over the weekend.

[requiemmg]

Sure thing, I'll let you know. Today snow on my panels, so no solar power ☀️

[IngmarStein]

@Setcover the armv7 image is up (https://hub.docker.com/r/ingmarstein/mielesolar/tags).

[Setcover]

looks good to me 👍 (again, neither miele device nor solar inverter to test)

I'll close this for now as the original problem "cannot run this program" is solved. Feel free to create new issues when other things pop up.
