I have a wemos D1 mini with two DS18b20 temp sensors on GPIO-14 and an fs300a water flow sensor on port GPIO-0
I also wired up a dual relay board to GPIO-4 and 5 but now I find that these ports are not selectable in the GUI for adding relays.
Can anyone tell me why this is? and if there's a workaround?
I have glued in this board and so it will be a pain to extract it and re-wire it.

GPIO 4 & 5 are default assigned to I2C.
If you don't need I2C, you can set those pins on the Hardware tab to -1 (not set).
Then those pins should be usable.

GPIO 0 & 2 must be high at boot and GPIO-15 is pulled down so that one is low if the unit is off. It should also be low during boot.
