I've been testing the flux live pricing and have some findings.

I'm on the latest version of the Android app, and Software Ver. M 3.3.8.4/S 1.5.1.5/CE.4.3.3

The settings work to sell and buy. It looks like by taking over timer 1&2 then reverting once the times are hit. but I've noticed it leaves some important settings in place when it's supposed to have finished.

• After charging it leaves the inverter in "priority battery" which means i keep using the grid until I wake up
  

• After selling it leaves the inverter in "selling first" which will drain the battery quickly if the next time slot % is set lower than your soc
  

• It also leaves timer 1 & 2 ticked for grid + gen charge ticked when it's complete, it reverted to the original times i had set but not the original percentages. It makes both 100% when charging, Which means my battery was set to 100% from 05:00 till 1600 and 40% from 16:00 til 23:00

For those using flux, right at this moment I'd recommend manually selling as these sticky settings could cost you a lot if you don't stay on-top of it.
