The SPIRIT Radonlogger automatically connects to a SPIRIT HUB or directly to an external LoRaWAN network if one is available at the measurement site. SPIRIT HUB connects via network cable.
A SPIRIT Radonlogger located within a radius of 200 meters automatically connects to a SPIRIT HUB. There is no limit to how many loggers you can simultaneously connect to a HUB. If a logger is not connected, it still measures and automatically connects as soon as it arrives within sufficient distance of a HUB or external LoRaWAN network.
