If you have multiple dogs (and even cats), the add-on sensor is for you! Each sensor allows you to create a unique profile for each of your furry friends, and you can even customize their access modes individually. You can link up to 3 sensors per door.
Each myQ Pet Portal system comes with one sensor at no additional cost. Add-on sensors are only recommended for multiple pets or replacements.
Please note, the collar sensor is not waterproof and should be removed for bath time or swimming.
