I have a temperature probe connected directly to my Venus hub and it is used to monitor the general temperature inside the battery compartment on my RV. I had set up an alarm rule to warn of low temperature but realized I had set it up incorrectly. I deleted the Alarm Rule but now the temperature probe does not show up on the drop down list for selecting devices for Alarm Rules. I checked the Venus device but it just shows Internal Temperature as an option. How do I get the temperature probe back so I can set up an Alarm Rule?
