The first field test of the IoT system took place at the end of January. For this purpose, a gateway and two IoT nodes were installed in the Jockgrim waterworks of the administration union for Water Supply Germersheimer Südgruppe. Measured data can currently be transmitted from a deep well and a mains pump. At present, the gateway is in the waterworks building. We expressly thank for the great support from Mr. Friedmann and Mr. Justen!
