Ultimate EMS with zero export

Arjen_Baatje · June 21, 2026, 10:32am

The car was and is still plugged in and API key is filled in. Looks like there is a relation between the status the Tesla app shows me. It is connected to the charger, but the option Begin te laden is visible .

Menno_De_Braak · June 21, 2026, 3:20pm

Hi Arjen, first please update the Ultimate EMS app to the latest version (1.6.20)

Once updated, can you send me three things?

Bug Report — go to Ultimate EMS settings, scroll to the bottom, click “Bug Report” and paste the output here.
EV Diagnosis — in the same settings page, click “EV Diagnosis” and paste that output too.
Screenshot of the Wallbox device — open the Homey app, tap on your Wallbox Pulsar Max device, and send a screenshot of the full device card showing all the values.

Thanks!

Version 22 already on my Homey, you are on a fast track!

Goodmorning! all should be fixed. There was a difference in how the wallbox and the tesla were sending the states back. One side note, your PV is putting out a negative power, is this on purpose?

Menno_De_Braak · June 22, 2026, 6:36pm

More of improvements done today, also quarterly prices from PBTH and then improved ev charging plan, prio comms when using car AND charger car comms. Let me know how this one works!

Menno_De_Braak · June 23, 2026, 11:09am

Ultimate EMS is now using PBTH for prices and dynamic charging etc.

Menno_De_Braak · June 23, 2026, 11:12am

version 1.6.27 is now ready for testing zero export capabilities. minor bugs fixed and bug report extended.
