Why is there a limit of 18 protect devices?


#1

I thought it would be nice to use nest for my homes 23 smoke detectors, things went fine until I hit the 19th device. Is there any plan on increasing this? I would setup two accounts, but I use the nest binding with openHAB my home automation system and it only can talk to one account per the nest API guidelines.

UL regulation limits the number of interconnected smoke detectors to 18. UL217 to be specific.


#3

Does this become a per structure limit of 18 protects?


#4

Correct, 18 per structure.
