Hi All,

I have tried to install the new Smart Tariff app in my dashboard. I have entered in the MPAN, Meter number , account number, and the API.

When I click on save, it says "service error"

Can anyone help?

I had a similar issue but my error was 'invalid API key' even after changing the API key!

Similar for me - API key

I got that when I tried the new smart tariff plugin when it was in beta testing. GE did eventually fix it so I could login. Looks like the problem still exists. 🙁

I configured the new one, and my battery charged at the cheapest rate for 1 day.
It then didn't charge at all, so I disabled automation and relied on the timed charge.

I've just woken up, and the battery hasn't charged again.
I've now reset to defaults, and set the timer back up...finger crossed for tonight.
