Cant add 1wire sensor

[prcdslnc13]

When I try to add a DS18b20 under the 1Wire entry in sensors I just get the blue status bar but no confirmation on the web interface.

When I am logging I get: 2019-02-28 10:59:33,518 - WARNING - terrariumSensor - OWFS file system is not actve / installed on this device! If this is not correct, try 'i2cdetect -y 1' to see if device is connected. 2019-02-28 10:59:38,553 - WARNING - terrariumBluetoothSensor - Bluetooth scanning is not enabled for normal users or there are zero Bluetooth LE devices available.... bluetooth is disabled!

There are 2 attached to phys pin 7. Any help would be awesome

Have you ssh'd in and run 'i2cdetect -y 1' as it suggests? That should give you the address

Hi, you cannot add 1wire sensors throught the web interface. When you have connected them according to: https://github.com/theyosh/TerrariumPI/wiki/Hardware#ds1820

Then you should restart once, so it will scan for it during start up. Adding sensors when the software is running, will not work. You have to restart/reboot after adding hardware.

Thanks for the clarification that cleared it up. This can be closed!
