I'm with Octopus Energy and with the agile product which has different units prices per half hour, is there a way to set up the inverter to charge the battery when it is negative cost, because if it is then i would like to know to be able to take advantage of this

Thanks

paulo have you added your info to the tariff card? there should be an automation you can use if so. If not, look at something like Home Assistant

paulo can also use the octopus r and d app to charge when price is below X pence. In your case 0

What's the Octopus R & D app?

Wavy Davy think of it as a dumbed down version of if this then that. Allows some basic automation based on tarrif Info.

you will need to register and then populate account details before all the tabs appear

Does it take a while to populate the tabs?
Have installed and filled all details in, Tariff account etc. have graphs showing correct tariff but only have graphs and my account tabs.

thewhalw21 I've tried this ie set to charge at 0p or below, but it doesn't work. It seems it doesn't pick up the negative values. Has anyone else had this problem?
