If I have this error during configuring the extension access??I put EU and my token generated:
sn_not_found

Hi Im really new to this and have started using HA to try and fix my issue. My EP Cube system discharges into my EV when Octopus Energy start it charging. Is there anyway to trigger my EP Cube to charge when the EV does?

@adamjs90 I’m currently weighing up whether to buy this system. This is the kind of automation I need, so I’m glad this integration exists. I’m coming from a FoxESS system which has full API control.

Do you want it to charge the EV and the Cube simultaneously?

Sounds like your system is set to prioritise usage as solar > battery > grid, so when you charge the EV, it pumps in from the Cube to avoid any grid consumption. If I’m right, you would need to change that priority to consume grid first, and therefore to force charge of battery. I do this overnight with Octopus Go at cheap rates.

For HA, you might have to detect a recognisable spike in the usage when you plug in the EV (presumably that’s at around 7kW – mine is only 10A so not as easy to detect) and use that event to switch the mode to grid first.

You might also want to prevent it charging the EV at all, and use the battery for your house, when prices are expensive. 7kW EV chargers will usually have this capability so your inverter priority is probably the only thing you need to change.

Great integration - thank you.

One thing I'm trying to do with it is to have a trigger change the EP Cube operational mode from TOU to Backup for certain triggers (and then back again without removing the TOU times). However, using this integration it doesn't seem to want to make the change in operational mode.

Any suggestions?

Many thanks, Geoff

@adamjs90 Have you had any luck with this? I'm considering getting an EP Cube system, and your example is one of the things I want to make sure I can deal with.

Is there an option in the EP Cube app to "force charge" the battery? I know that with other inverters, if the battery is set to force charge, then it won't discharge while in that mode. This would allow our EV to pull from the grid instead of the battery. If there isn't a specific mode for this, it's often found as one of the Time Of Use (TOU) options. I'd be very interested to hear from you if this is present and if it works as I'd hope.
