Greetings, we are starting to scan OT devices and are having a hard time to make it work. Follows the symptoms:
Has anybody experienced this kind of issues?

We are just testing out the OT scanning and are running into similar issues. You do need to be very aware of the protocols that are supported, as described in knowledge base (OT supported protocols). Of course, you have to specify which protocols you want to use in your scanning target definitions, and even just including the included defaults will only recognize those that communicate on default ports.
In essence, to really get value out of Lansweeper OT you need to know your OT environment; e.g. what protocols are supported by the devices you want to identify and how those devices are configured. I expect a lot of organizations may not have that knowledge in house; if they do, they are probably already using something else to monitor those devices.
It certainly isn't a product you just 'drop in' to your environment with an expectation of immediate results. At least, that is my experience so far. Time will tell.

Hey StillGoing,
Thanks for your reply to this question!
I wanted to elaborate on one thing: of course, you have to specify which protocols you want to use in your scanning target definitions
This is actually not completely correct.
The latest version of the OT scanner (currently 3.3.8) actually has both an 'Advanced' and a 'Default' option.
Hope this helps you and others
Feel free to try the default option if you haven't already and let us know if that works better or is easier from a configuration point for you!

The devices that are listed in your screenshot are indeed all switches. The current OT Scanner doesn't 'deepscan' those devices as it was build specifically for OT devices. In future iterations we are aiming to also deepscan IT devices from the same Discovery Hub but for now you would indeed still need the IT Scanner if you want all information (like switch port mapping, serial, firmware etc) for your switches/routers/...
Best chances of finding all your devices in an OT environment is by installing a Sensor on a windows box (physical or virtual) and place it in the VLAN that you want to scan. This should ensure devices are being picked up properly. Often there are numerous firewalls in place that may allow a ping but block all kind of other traffic/communications over VLANS that is needed to perform a correct inventory of a device.
