@fosdem thanks for quick answer! I will plan for using a power socket and giving a socket back by means of socket multiplier (extension lead).

@fosdem ok so PCB making with sensors sourcing and assembly comes to 33 EUR per unit (if I do a big order). Sourcing USB power from mains socket is more expensive than I expected, so I am calling for devroom and stand owners to adopt a sensor, i.e. to look after it and make sure it's fed organic local-grown electricity (USB-C 5v, no PD should be needed).
