Is there a ground monitoring device?

Question

Do it yourself

I would like to have a device in the cabinet that will measure the quality of grounding along several lines. The essence is as follows:
- the device is powered by a single-phase 220V network;
- the device has its own "control" grounding;
— the device has an Ethernet interface;
— the device has several ports for connecting control lines;
- you can rob cows to add the presence of grounding on each of the ports to any infrastructure monitoring via SNMP.
From one port of the control line, it is enough to connect an insulated wire to the ground contact of any device. The device determines the electrical parameters of this connection for each port.
At the same time, as usual, you can see the status and history of any ground control port - there is a ground, there is a local loop, there is no ground, there is a bad ground, there is a phase instead of ground, etc.
Question is where to buy it?
PS I have been wanting such a device for two years.

Answer 1

Make a measuring bridge + amplifier, attach an arm with a w5100, or just do it on an arduino, and you will be happy.
As for the "stories" - this can be programmed, but it is clear that it is cheaper for you to do it yourself, because it will not come out cheap. Although it’s also not difficult to make a site based on static files on a SD card, everything is described, there are libraries, there are examples.
