HWG-STE 1 wire support

Postby PurpleBlue » Sat Aug 10, 2019 2:55 pm


Recently i got a HWG-STE (https://www.hw-group.com/device/hwg-ste) from the HW-Group with one temperature sensor.
The HWG-STE has 2 RJ11 conectors, for reading out 1Wire devices.

The temp sensor i got is a 18B20 (SMD) connected with 3 wires and a capsitior, and a resistor (SMD 223 - 22K?)
The sensor works fine in both of the RJ11 ports.
By connencting/disconnecting it will show up in the controller after 1 or 2 seconds.

When i connect another 1wire device (18b20 tempsensor) to the other RJ11 connection, (same as the other port) it will not been reconized.

Has someone expirience with the HW-group hardware? (and adding sensors)
Could it be, that only some serialnumbers (known by HW-Group) will be allowed?
Or is it something I do wrong? :-)

Thanx for advice!
