With SetupHelper and GuiMods the Raspberry Pi with Venus OS can make use of up to 6 relays. They are all set up to be active on low current. Many relay boards to buy are fixed to be active on high current, only some can be configured as both low or high.
Is there a simple way to edit this function (file edit with SSH) to make use of a active high relay board connected to the RPi ? And make the change survive a FW update. Or is the best way out to find relay boards that is jumper configurable.
