Hints and FAQ
Eco charging modes
Eco modes let the charger optimize charging based on available solar surplus, flexible electricity prices, or both. Instead of just charging immediately at full opportunity, the charger reacts to external conditions and only charges when the selected Eco strategy allows it.
Eco: PV Surplus Charging
Set the charger into Eco: PV Surplus mode. This can be done from the device UI:
or from with a action flow card Set charger mode to ...
Finally start feeding your grid power details to the charger:
When grid power changes, sent it to the evCharger as pGrid value (the first parameter in the card. Set the other values to zero.
When grid power is negative, this is the PV Surplus amount that will be used by the charger. Go-e Charger calculates internally the target power to use and switches 1-phase/3-phase charging automatically.
Eco: Flexible Price Charging
Set the Flexible Pricing tariff provider first in the Go-e mobile app.
Set the charger into Eco: Use Flexible price mode. This can be done from the device UI:
Then set the price limit in your currency for the maximum tariff. Note that this is not in cents. So if you have 10ct/kWh as a limit on the mobile app, the it is 0.1 in go-e Homey app.
Use the action flow card Set flexible price limit to... to your choice. Use a calculated tag for the value to add more automation.
Eco: PV Surplus and Flexible Price Charging
This is a combination of the above Eco: PV Surplus and Eco: Use Flexible price, which ever qualifies will be used. Utilize the same flow cards as above.
Daily Trip charging modes
Daily Trip modes try to have the car ready by a chosen time. The difference between the four modes is what the charger is allowed to optimize while working toward that deadline.
To use any Daily Trip modes:
- Set the charger to one of the Trip modes, either from the device UI or with the flow card
Set charger mode to ...
- Set the trip target with one of these flow cards
Set Daily Trip kWh target, if you know how much energy you want to add.Set Daily Trip SoC target, if you know: the car’s current SoC, target SoC, battery capacity in kWh and target time to be ready.
The app also exposes a Not Enough Time alarm. If that becomes true, the charger has determined that it cannot fully reach the requested target before the selected time.
Trip: Use PV Surplus
This mode follows the Daily Trip target, but prefers charging from PV surplus whenever possible.
Use this when you want the car to be ready by a specific time, while still prioritizing solar surplus.
Send grid power updates to the charger using the Set PV surplus info flow card
Trip: Use Flexible price
This mode follows the Daily Trip target, but prefers charging during cheaper tariff periods.
Use this when you want the car ready by a certain time and also want charging to stay below a chosen price limit whenever possible.
Your Go-e EV Charger will calculate the optimal charging rates based on your Tariff settings on the charger.
Trip: Use PV and Flexible price
This mode combines both optimizations. It follows the Daily Trip target while using PV surplus and/or cheaper tariff periods whenever they qualify.
Use this when you want the car ready by a chosen time, but also want the charger to take advantage of both solar surplus and flexible pricing.
Trip: No PV and No Flexible price
This is the simplest Daily Trip mode. It follows the trip target and target time, but without using PV surplus or flexible price optimization.
Use this when your main goal is simply to have the car ready by a given time, without any energy-source or tariff-based optimization.
