Rotronic HF532 not connecting

[kentrols]

I have a number of HF532-WB1XXLXX Temp/RH units with HC2-S HygroClip2 sensors installed in an agricultural application. We are connecting the ethernet for remote monitoring/diagnostics and the two analog channels for signalling into the control system. We've just installed the 3rd unit (the first 2 installed and worked without issue) but for this unit we're not getting any analog signals. I can see the HF532 on the network at its static IP address using the Digi Device Discovery app and can open its webpage using the default login credentials. All of the settings appear identical to the 2 working units but when I try to connect to the HF532 using HW4, nothing appears. I have HW4 opened with the 2 working HF532 units but the 3rd will just not connect. I've tried "Search for Ethernet Master" and "Search for a specific IP" with no success. What does it indicate when HW4 cannot connect to an HF532 that can be seen with the discovery device? Is it an issue with the HC2-S?

Thanks for your quick response. The network doesn't have a DHCP server but I tried a few different IP addresses with the same result. To clarify, I can see the HF532 on the network and can open the webpage and view/change settings without issue. The issue is connecting to the unit with HW4 and viewing the sensor settings and readings.

Regards,
Ken

I was lucky to find this article when I was having the same problem. basket random

It sounds like the issue may not be directly related to the HC2-S sensor, as the device is visible on the network and accessible via its IP address. Since you're able to connect to the other HF532 units, there are a few potential areas to check: Network Configuration, HW4 Software Version, Firewall/Security Settings, Analog Channel Configuration, Sensor Calibration or Failure

That's frustrating! I've had similar issues with network devices before. love tester

Turn off any firewall or antivirus software that might be preventing the HF532 from communicating with your computer. If the HF532 is linked to a network, make sure it has authorization to speak with your PC.

The problem is still that the HF532 connection is unstable.
