I am new on this forum. As an electrician in Denmark, I have just gotten a fountain to maintain. The control cabinet and pumps are all underground in a couple of wells.
There are a lot of monitoring and time is spend / wasted lifting the heavy manhole covers and driving to and from the wells. I would like to install a plc to monitor the few settings I really need.
Are there some with experience of how and what type of equipment? I am considering a siemens LOGO with a communications module and just buy a sim card.
Is it better to use prepaid 2G, 3G or 4G or only data sim card? Also with or without pin code?
It is not possible to establish a wired communication connection but the wells have of course 230 V mains and is very close to a phone tower.
