Can a good Automation out perform Amber For Batteries?

Configuration
1

I recently installed Home Assistant, I live in Australia and have Amber Electric as a power provider. I have 5kw of solar panels, and a Tesla Powerwall 2 (13.5 kwh)

Amber Electric offers a service where they will charge my battery when the power is cheap, and sell to the grid when the FIT is high, with the aim of making me money.

While waiting to be approved for that service, I have configured HA to buy when the price dips, sell when it’s high, and use the battery at other times.

I am sure other people are doing something similar, so I am curious to know:

  1. If you have tried both Amber for Batteries, and HA with buy/sell parameters, which one worked out better for you?
  2. If HA was more profitable, what parameters did you use to control buying and selling?

Currently I buy whenever the price dips below about 16c. I sell whenever the FIT goes above 30c, and use the battery at other times. Plus, as a safety mechanism, I only allow selling around dawn and dusk.

Brilliant!

How have you found it over the past few months?

Care to share more about your automation? Are you using Node-Red or other logic platforms?

Have you implemented any Solar Curtailment to prevent cost exposure on negative FIT?

And have you compared it to the SmartShift feature they offer?

Friends and I also have Solar+PW2 and are just getting into Amber, but as we are all heavy HA users we are looking at all the ways to maximise the returns :smiley:
