I also got the error message when logging in, but this is the way it always worked.
I guess Athom or Smappee changed something which causes this error.
There isn’t much I can do about it.
Maybe someone can ask Smappee if they changed anything regarding API authentication?
I guess Smappee changed something, other oAuth2 implementations in the apps I created do work as expected.
Nice to know I’m really not the only one. How long do you have your Smappe installation running already (without and with homey integration)? Maybe there’s something there in the manufacturing year or so, I have one that was originally meant for load-balancing an EVbox charger (Evbox and Smappee discontinued their collaboration soon after Smappee started their own line of chargers).
Hi all, just FYI, I’m a developer at Smappee and we are tracing issues with certain user accounts not being able to access our API due to issues with the OAuth2 authentication. So we are aware of this issue and working on getting it resolved.
Thank you for the clarification, much appreciated.
Hi Edwin,
First of all, thanks for creating this great app and making it available to all of us! Great work!
I couldn’t find a way to send you a DM, so I hope it’s fine to address my request to you this way…
I wonder if there is/could be a way to set the Smappee charging speed (in Ampère) from within homey. I found out the Smappee ‘smart charging’ option isn’t working correctly in combination with my home battery, so I would like to find a way to have homey set the Ampèrage (charging speed) instead, based on the power I’m injecting into the grid (measured through my Homewizard P1 meter).
There is an option in the Smappee smartphone app (slider) to set the Ampèrage of the charging station when using standard charging. Would it be possible to set this value through the Homey app as well?
If you need any information or access to my smappee station, please let me know.
Thx in advance!
I created a new test release of the app (1.4.0).
Please share your feedback!
Hi Edwin,
Thx for this! I see you implemented the ‘Dim’ functionality on the Wall Charger, is this as a reply to my question of 27/03 (request to be able to update the maximum charging speed)?
If I implement this in a Homey flow, it changes the clarity of the LED of the wall charger, but not the maximum charging speed of the wall charger.
I hope setting the maximum charging speed is available through the Smappee API, I have no idea actually…
Hi Edwin.
Again - Thanks a lot for your help “back then” adding my “smappee plus” to the app.
I might need you assistance again 
I think Smappee changed something in their API when updating there phone-app 5-7 weeks back. I also struggled with the OAUTH, but it worked again after a week or so (i wrote Smappee).
I believe the variable “Effect” now shows the total use in the house - unrelated to the production of the solarpanels. Before if was the total enegy comsumption - solar production. Being negative if using more that produced and so..
I have plenty flows working after this, and I can’t find the corrosponding values in Homey so that I can change it.
Is this possible to adjust anywhere?
(sorry for bringing my problems to you - but I hope it’s quite simple to answer 
)
Snip from phone and Homey…
2.254 (effekt) = 2.08 (house) + 0.18 (always on)
I’d really really like the 3.29 - power in/out information to be available like before.
Thanks a lot in advance…
Dennis
