It stopped working for me. When i go to the smappe integration and “repair”, the client id and secret are empty. Trying to login responds with invalid login and forwards me to [app1pub.smappee.net](http://app1pub.smappee.net) to grant permission, which is already done. I tryed to temporary remove permission, but this ends up in an internal server error at smappee: ```auto URI: /dev/v3/oauth2/auth STATUS: 500 MESSAGE: Server Error SERVLET: org.apache.felix.http.base.internal.dispatch.DispatcherServlet-42f0defa CAUSED BY: javax.servlet.ServletException: org.glassfish.jersey.server.ContainerException: org.apache.oltu.oauth2.common.exception.OAuthSystemException: No locations were specified CAUSED BY: org.glassfish.jersey.server.ContainerException: org.apache.oltu.oauth2.common.exception.OAuthSystemException: No locations were specified CAUSED BY: org.apache.oltu.oauth2.common.exception.OAuthSystemException: No locations were specified ``` I guuess, there is a problem at the smappee server ---

Hi Edwin, I love the app. When it works, it really delivers some automation I was expecting from Smappee natively. Unfortunately, I cannot get the app working anymore. Here is the issue I have at the authentication stage. ![Capture d’écran 2024-03-19 à 11.46.48](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/d/f/df3a32d1d30f606f8a44a75fa598567a8d37a9a3.png) Can you help with this?

Hi, I’m trying to add another EV Wall charger to the Homey Pro. After selecting the brand Smappee I’m getting an error saying “Missing parameters: client\_secret client\_id” Where and how to I fix that? ---

That is weird. When I added 1 EV wall, you shouldn’t have to login again when you add a second charger. It should use the same credentials. Can you try to delete your device(s), re-install the app, and try to add them again? – Edwin ---

All fixed - Due to the awesome creator 😃 _Hi…_ _I have an Smappee Plus - Love that thing!!_ \*But @evdpol I can’t figure out how to add this to Homey? \* _I have recieved API credentials, and I go through all into Smappe longin and choose my home - but no matter what unit I have chosen, it returns “no new units found”._ _Is this lack of support for Smappee Plus?_ _Is there anyway this can be included in Homey?_ \*I would REALLY appreciate your support (or others) on this… \* \*And I’d happyli give you my login credentials \* _Thanks_ _Kind regards_ _Dennis B_ _Denmark_ ---

> [@evdpol](#): > > FAQ > > Why is my power negative? “Why is my power negative” in your FAQ doesn’t give me a solution. My power is always negative with my Smappee Connect also at night. I have other power reporting devices and they report the same values but positive as is correct . Are you familiar with this behaviour? ---

Does it show something different in your Smappee app? With very little information, I’m thinking if your Smappee is set up correctly in the first place? The effect is shown as negative when you use more power that you generate. Works perfectly here. Values in smappee app follows the values in Homey exactly. Add more info to get more help ---

Sorry I didn’t mention. Yes in the Smappee app and web dashboard positive values are shown. I’m using the same Smappee setup for over a year already and all values are (still) correct. As said the FAQ already states to take in account solar production. As an installer I’m familiar with that. However in Homey since installation about a month ago positive ‘power’ and ‘consumption’ both noted in Watts are inverted, negative values (during day with solar production) are correct . ‘sleep consumption’ is displayed quite correctly (just as poorly as within Smappee dashboard itself.) Re-initialisation, installation and maintenance attempts do not fix the problem. ---

Well, I can’t tell what is not correct from here, without more information like: - What device? Connect/Genius/Plus etc. - Which value(s) are not displayed correctly? What did you expect to see and why? - … You could send me your login details via PM, so I can take a look. I need the following information to debug: - Client ID (provided my Smappee Support) - Client Secret (provided my Smappee Support) - Username (Smappee dashboard) - Password (Smappee dashboard) I send you a PM myself, because new members cannot send private messages. – Edwin ---

Hi, Recently acquired a Smappe EV Wall & Genius system. Was able to connect both of them without problems, but my EV Wall never shows any usage, although it does show correctly the status?!?!? ![image](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/5/c/5c44fe410665d01a564f3c8009ad0b0fb40fbaad.png) Any idea what might be causing this? Anything I could provide to try and find the root cause? Thanks in advance! ---

I am reviewing the Smappee app and I already changed a few things. One thing I noticed, is that I never receive any negative “Production” value (solar) from the message service. It does not become negative on the Smappee dashboard widget also, but it is possible: ![Screenshot 2024-12-14 at 02.42.50](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/c/1/c12872332985d7b23f19d2eca38ee7bc9603c34e.png) ![Screenshot 2024-12-14 at 02.43.08](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/e/6/e6edc22520c5501524ad438a557876c76032944b.png) I have removed 1 power capability, so it now reflects the realtime widgets on the Smappee dashboard: ![Screenshot 2024-12-14 at 02.46.13](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/d/4/d48db11e5b255544199b5f7a24dd4b71d12f15be.png) Want to find out how to get the negative solar power (production) value. Also, I’m not sure how you can produce 469W at 01:55 in the morning, but that’s not my problem I guess 😉 ![Screenshot 2024-12-14 at 02.48.32](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/2/b/2b4c1abbdc07377c2660239cc3c34c362fb87187.png) ---

Hi Edwin, everything ok? When producing in the morning probably the solaredge battery, at least that’s the case at our place… 😁 Would it be possible to add smappee to the New Energy tab in homey? Greetings, Willem Jan ---
