Does your powerwall normally export to the grid with a VPP or similar settings?
Does your utility actually allow you to export to the grid?
Please explain which steps you did in which order.
Can you show your utility rate plan from the app?
I’m on Amber with Ausgrid in NSW.
I got the PW installed last Wednesday, no VPP yet.
Amber is switching me over to the Ausgrid 2 way Tariff. It may take a few days still.
The steps I took. After I set the peak window and pricing, I enabled Time-Based Control and then just waited.
That great, lots of folks on Amber are using the TBC hack for exports.
The only thing I can think of is your prices could be more dramatic to encourage exports.
You could use my settings from above.
Wait 15-30 minutes for them to take effect.
Switch to TBC mode.
Wait about 5 minutes for the export to start.
Thanks. I will try this out.
On another note, do you use Smart Shift or are you strictly EMHASS?
No Luck tonight either. 
I can run both in parallel, but I wasn’t liking the times SmartShift was hitting the Preserve mode during the day so I’m pretty much running only on EMHASS, including battery exports.
With my TBC settings you don’t need to wait for the evening peak, anytime (except 00:00-01:00) that I switch to TBC mode the battery starts exporting.
See if you can generate this type of chart using the history card for your site.
You can see my system switch to TBC (Gray colour on operation mode) from 4:48pm - 5:39pm, during the highest price of the day, and the battery exporting to grid. (15 kW =3x 5 kW)
At 9:31am, during the lowest price of the day, you can see it switch to Backup mode (orange colour) and charging the battery from the grid. (11 kW = 3x 3 .3 kW)
I’ve requested to go on to Smart Shift. I’m hoping that the onboarding process will enable the battery to export (without smart shift). Maybe there’s something on Amber’s side that is preventing this until ss has been enabled.
I was finally able to export today! Happy days!
Edit: I did not change anything. It just started working on its own.
