ano,
I was watching a webinar yesterday that showed there is a box to check in UPStart to have each device (e.g. dimmer) send the status if it was used locally. If you check this on all devices, is that really any different than what you mentioned regarding HLC ("The nice part of HLC is the Omni automatically polls switches after they were switched so it tracks their status.")?
Good question. Yes its true when you switch a light it can send its status, and it works, but there is a problem. If you switch several switches at once, sometimes the reply signals get lost. That is problem #1.
But there is a bigger problem. Many people use UPB links which can switch many lights all at once, and switches DO NOT transmit their status when changed with a link. If the switches did transmit, you may have 10 or 20 switches all transmitting at once and it would not work.
Leviton has created a great solution with HLC. What you do is segment your switches by room, with up to 8 per room. (You can use two if you have lots of lights in a room.) Then you use the Leviton ROOM controller to send links to the lights in a room. Each room has 4 links assigned plus all on and all off. For example in my kitchen I have "Normal" "Cooking" "Dining" and "Party." I activate each link and it sets up to 8 lights to the correct dim levels. Then the panel waits a few seconds, then polls each switch in the room.
Instead of sending the status when a switch is switched, the Omni does it a different way. All switches are programmed to send a certain link when switched on or off. When the Omni sees that link, it knows which switch set it (its coded in the link packet) and the Omni polls that switch. So status is not immediate, but it usually is correct within 10 or 15 seconds. The Omni has a way to poll many switches fast so it doesn't take that long.
Leviton also has a HOUSE controller. These have one button per room, and you can control the whole room with one button.
In any case, If you have an Omni, HLC is really something to consider. It works really well if your willing to take the time to learn how to set it up. If you search, Worthington has a presentation on HLC. Its worth downloading.
