@proebstle sorry for the late response, I tested on my lab and it's working. Please:

• be sure you are using the latest commit
• be sure you restart both netbox and netbox-rq
• please re-set the discoverable_mode and save

Moreover I'm fixing NTC templates here: https://github.com/dainok/ntc-templates
