Help with Zappi & Nissan Leaf

There could be an issue with the time that the surplus is available for, that prevented charging for me in eco+ previously.

A surplus above 1.4kw should start a countdown timer and only when that timer gets to 0 will the charge start, if the surplus is reduced to below 1.4kw any time during that countdown, the countdown will reset. You should see the countdown starting on the Zappi display.

The menu to set it is in Charge Settings, eco+ settings, Start/Stop Delay.

In my case, I think the timer was set to 30 seconds, and there was a 2kw surplus, but the cooker had a ring on simmer, so every 20 seconds or so the thermostat on the ring would click on for a few seconds to heat up, which would use up the solar surplus for that short period, but it would stop the countdown timer, so the car would never charge.

I had suggested to myenergi on their support forum that they could consider splitting that timer into 2 different timers, one to start the charge and one to stop it, so I could start the charge once there was s surplus for 10 seconds but only stop the charge once the surplus has disappeared for 2 minutes for example. They didn't implement it though.
