    Thank you for fast and sincere reply. 

    I was planing on only using sms messages for data transfer. A bit of a hazzle with special codes for commands etc. but also simple.  As this is a voluntary project I finanse with private hard earned and taxed money, it is maybe overkill with the equipment you mentioned. I looked up the prices.

    Doing that now, even though it can still be done is a recipe to be hacked." end quote.

    Is hacking also a problem with sms text messages?

    Devices from Rockwell Automation and Phoenix Contact come to mind." end quote

    If I could deduct the amount on a company's  annual tax return it would be great.

    I only need a few sms text messages with amount of water filled per day or so. Nothing intensive and nothing risky in processing. Only monitoring.

    Hello Everyone

    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.

    Yours faithfully
