I want to charge 2 curtain devices via one solar charger placed in a window. One panel would be ideal as I don’t want to compromise the view out of this window by more than one panel. I realise that solar panels are not particularly efficient through glass but think that 2 smart devices could be charged enough, particularly if controlled by automations that check charge levels in both devices.
There appear to be a number of 5v output panels available. However, this only works if I can have a smart switch of some variety in between the panel and the 2 devices. This could send incoming charge down the appropriate charging cable once an automation identifies which needs charging.
I see a lot of smart switches but these seem to be for light fittings etc. Is there a smart switch for my particular purpose?
