v1.22.1 real_mode

Real_mode as mentioned on #10 works for backup or self_consumption but not autonomous. It only seems possible to set that through the app now. This is the case regardless which mode the unit is currently in. As I have now backup capability I'm stuck in self-consumption mode unless I use the app.*

Anyone achieved a workaround?

  • reason for changing is the way metering works in the UK. Autonomous appears to try and achieve a net import export of 0 whereas in the UK once imported the import meter is incremented, and we have a generation meter rather than an export meter. So you want to import zero, generate loads, and self-consume as much as possible whilst avoiding exporting. I put mine in autonomous mode when the sun goes down, to charge with off-peak electricity, then back in self-consumption when the sun rises. Or at least I did!

the GET operation to determine current mode will return autonomous, but it is not possible to set it using the POST operation as far as I can determine.

There is detail on the messages from the app to the mothership on tariff band information set when you set it using the app available on the TMC forum, so setting parameters for TBC via the mothership is achievable, but not direct local control.

It is not possible to switch to autonomous mode - if previously set up via the app - locally.
