    Spam protection. How many is SIX times six?

  • Can I connect sensors other than temperature and humidity (e.g. illumination, voltage etc.)?
    No, HWg-STE plus only supports temperature and humidity sensors. For other sensors, we recommend the Poseidon product family.
  • Can I connect to HWg-STE plus device simultaneously Temp and HTemp sensor?
    Yes, HWg-STE plus supports in this case up to three variables (2x temperature, 1x humidity).
    For more sensors, we recommend the Poseidon product family.
     
  • Can I connect sensors by other manufacturers to the DI (Digital Inputs)?
    Yes, connect a relay output or a dry (voltage-less) contact of any device.
  • Where can I find the MIB file for connecting with my SNMP software?
    The HWg-STE.mib file is available at the “System” page. Simply save it and import it into your SNMP software.
  • Can I control relay outputs with HWg-STE plus?
    No, the HWg-STE plus network thermometer only features digital outputs. For relay control, we recommend the Damocles, I/O Controller or Poseidon product family.
  • Can I connect the Pt100 or Pt1000 external temperature probes to the HWg-STE plus?
    No, external temperature probes Pt100 and Pt1000 are connected via the Converter 2xPt100 1W-UNI. This product can't be used with HWg-STE or HWg-STE plus devices.
  • How can I plot the temperature in a graph?
    To temperature monitoring, use the supplied HWg-PDMS software.
  • Where can I find SNMP Trap settings?
    HWg-STE plus does not support SNMP Traps. If you need them, use Poseidon or Damocles products.
  • Can I use the HWg-STE plus for Dry Contact monitoring?
    Yes, it will send you an email when digital input change. You can also monitor it by SNMP.
  • Can I use STE without a SNTP server?
    Yes. The SNTP server is used to synchronize time and to initialize the clock after power up. However, the time shown in e-mails will be incorrect.
  • How can I create a report with recorded temperatures?
    Use the supplied HWg-PDMS software. Recorded values can be displayed or exported to MS Excel.
  • Where can I find the prices of your devices?
    Ask our distributors, or request a quote directly from us using the form at this page.
