Corona can’t stop us

Coronavirus (COVID-19) is roaming across the globe but can’t stop us. Still, there is no vaccine but is clear that one day when there is it has to be transported in a proper way – a corona vaccine container with IoT monitoring solution from ThingsLog. Thus we have released our vaccine container monitoring solution based on a low-power data logger, portable vaccine container, and highly accurate temperature/humidity sensor.

ThingsLog for small and medium utility operators

There are many small utilities accross the globe. Most of them emerged from the cooperatives and deliver either water or energy to a couple of villages or a small town. Small utilities are our best and most vallued customers. We help them in management and monitoring of their distribution networks. We also build custom IoT/LoRa/LoRaWAN networks for remote meter readings. By this we solved some of their biggest problems: how without enough personal to be able to manage the network in proffesional way and to be able to bill subscribers on time.
