Flair works with Lasko devices that have an LCD screen! If your Lasko device has a screen that shows the current temperature and state, you will have access to Flair's full feature set. If you do not have an LCD screen, you may be able to use Flair as an internet-connected remote (the Flair App will let you do everything that your remote currently does, but through your phone).
The Flair Puck works with your mini split, window AC, or portable device as a smart thermostat. The Puck is the only smart and affordable option that works with these systems. The best part? It's wireless after the first Puck. Ditch your old-school remote.
