Hi @viguera, @jason_coleman ,
The ecobee temp sensors can be refreshed every 5 minutes w/o any issues. The main lag issue
is with the remote motion sensors as there are some ecobee API limitations as stated at the ST community
wiki:
http://thingsthataresmart.wiki/index.php?title=Ecobee3RemoteSensorInit#Known_issues
So, the remote motion sensors cannot be used for real time HA scenarios as there is a minimum of 30 minutes lag for the ecobee3’s smart away or follow me features. Actually, some ecobee3 users observe
sometimes up to a 2-hour lag before the smart away feature kicks in at their home.
See this thread for more details on the lag issues from another specialized forum:

My smartapps, which leverage the unique set of features of MyEcobee device, can reproduce the smart away & follow me features within few minutes (configurable option) with any ST connected sensors.
See this thread for more details:
Regards.
