Best practises for incompatible EV’s and wall chargers

This article is for customers whose EV or wall charger isn’t currently compatible with Amber for EVs automation but are an Amber customer.

Quick summary

If automation isn’t possible, you can still reduce costs by using schedules, off-peak/low-price windows, and manual start/stop based on the Amber price and solar conditions.

Check whether your vehicle / charger is currently supported in: What vehicles and wall-chargers are supported?

Set a charging schedule inside:

Suggested approach:

Pick 2–3 recurring windows that usually have cheaper or greener energy (e.g., late morning on sunny days if you have solar, and/or overnight if prices are often low).
Keep the window wide enough that the car can finish charging even if charging starts later than expected.
Check the Amber app on the live prices screen to see what the price forecast is looking like.
Typically the cheapest part of the day for power is midday.

Avoid running multiple “smart charging” systems together as they can fight each other with competing controls.

If you’re testing automation and things look unreliable, temporarily turn off all but one controller.

Ensure firmware/app for your charger and vehicle are up to date.
Make sure the charger has a strong, stable Wi‑Fi / cellular connection (poor connectivity can break remote control).
If the charger frequently drops offline, test with a different network (e.g., hotspot) to confirm whether it’s a connectivity issue.

If charging from excess solar only is important, consider using your vehicle’s charge current limits and schedule to avoid importing from the grid.
