Fronius & Tesla Issues with Homey Energy

Hi Community,

With the release of Homey Energy (wasn’t on the beta) I am experiencing several interesting issues. I have a Fronius Gen24 3-Phase Inverter & combined Smart Meter + Tesla (Car & Charger devices) & Tesla Power Connect community apps. These have always worked well and accurate with readings within the previous Energy tabs. All of these apps are configured with Energy settings. Important to note I did already have Power by the Hour running for last Month, and reconfigured to exclude from Energy & also deleted manually (last month) deleted data from Top Consumers.

Energy Issues :

  1. Missing Summary Data on Top of Screen
  2. Today & Yesterday Navigation Buttons are Date - 1 & Date - 2 Respectively (If you select Today it goes to Yesterday Date, if you select Yesterday it goes to 2 Days ago)
  3. The current active Solar & Energy total (between House & Graphs) are missing for Today but are included Yesterday (Perhaps related to #2)
  4. Missing current active Electric Vehicle total (between House & Graphs) Note : EV charging animation working on House image. This was only activated yesterday are exhausting Tesla API $15 limit (changed from 1m to 5m sampling + new $5 monthly limit)
  5. No total Numbers on Energy & Solar Graphs even though graphs are displaying data.

Anyone experiencing these issues?

Perhaps I did this too early, but overnight I tried creating a VD (with new Power By the Hour device) as per Noob question: why does "solar" stay empty - #3 by Eternity and in the morning (when solar producing) it started to show 1 mWH on the top summary line (issue #1), perhaps related to meter_power displayed in kWh? I decided to delete these new devices and I reset Energy & Solar for today. I did keep my native Fronius devices (with Energy settings on) in parallel during, which might be related to problem. Either way i figured this should be required for native feature and I raised bug on Fronius app GitHub. Homey Energy not Reporting · Issue #64 · ThomasHoussin/com.thomashoussin.fronius · GitHub to confirm if this has been tested with Homey Energy.

Sorry for the long post, for now I am going to leave for 48 hours to see if things stabilize and will consider raising support case. I did read people have had success after daily data reset.




No detailes answer but some hints. I can’t check my setup in detail atm.

  • Tesla car is provoding a meter_power (summed charging amount after cable disconnect). But this will only appear in usage list.
  • You need meter_power and measure_power for the EV charger device (wallbox). And this device must be class ‘evcharger’. You could check this in Homey Developer Tools
  • I’m using Fronius HomeAssistant integration. But I can remember that the Fronius power meter only has meter data for in/out, not for houe usage. I had to create a helper entity (virtual device) that sums up the usage (W) into a meter (kWh). I think that’s what you did with PBTH.

Thanks @RonnyW for these insights. Sounds like unless the apps have these metrics aligned VD have to be created. I have HA integration so that one is easy to test. Appreciate the assist.

TBH, when HA introduced energy monitoring a few years back I had several formulas in my yaml to calculate energy correctly. Today in HA it just works OOTB. I am hoping the Homey team are approaching key “Energy Provider” app devs to update their code to feed Homey Energy the correct time series dataset. Perhaps also creating a filter in App Store to advise which support Homey Energy.

Any others have same issue (especially with Fronius & Tesla apps)? If so, I’d be interested to hear about your specific workaround configuration. Noob question: why does "solar" stay empty - #3 by Eternity Is something I need to retry again and perhaps disable the energy inclusion within Homey on the source devices after creating the VD devices.

Anyone managed to get the Electric Vehicle icon working? I have both Tesla Homey apps installed and even have published HA sensor from Home Assistant (thanks to help from @RonnyW ). Currently I see the animation to the Electric Car icon and the Eva Charger in Top Consumers, but no separate EV with Charge % and whether plugged in as per marketing pic.

@RonnyW Tesla app has Class of car (homey:app:com.tesla.car:car) and capabilities like measure_battery, however other capabilities like charging_state are treated as Battery Sensor (homey:app:com.tesla.car:battery)

Dev team what is required to make this work? What Class and Capabilities required to make this EV Car status to work with Homey Energy summary page as per sample.

Yes, I have to add the ‘electroc car’ setting for the car device (and to add the charging state). It will come, but currently I’m working on other technical things in Tesla app. So give me some days :upside_down_face:

The car will show SoC and charging state.
The EV charger will provide energy data for the charts.

Thanks @RonnyW for your ongoing support of the Homey community.

The new functionality will come with Homey FW 12.4.4. So no idea when it will be available as stable version.
