We use Deco M5 as main deco and added 3 other M5's and 3 E4's in our Hotel with 11 rooms. Every week we have new guests so also new devices.I noticed that a list of online and offline devices are visible in the Deco App. But also 'online' devices that are not here anymore. I think this is strange but I am also worried that at a certain time we reach the maximum number of devices.

Question 1: this maximum of 100 devices is about only connected devices (also teh online ones that aren't there anymore)?

Question 2: how can I remove old devices to clean up the system, or is this not possible or necessary? 

Question 3: what advise could you give me to handle multiple users/devices over the time?

Thanks in advance.
