SEND_LEVEL and LEVEL_EVENT

sonny · November 2012

I am writing a Duet Module for the new Aprilaire 8800 and having a goofy issue involving levels. Could be in the SNAPI sub-system somewhere, (or a brain-fart on my part) but I thought I would run it by the forum.

Use Cool Setpoint for example...

LEVEL_EVENT [vdv, HVAC_COOL_LVL]
{
     coolsp = LEVEL.VALUE
}

BUTTON_EVENT [ui, 1]
{
   push:
   {
        send_level vdv, HVAC_COOL_LVL, 75
   }
}

If I get a setpoint adjustment from the thermostat, the level updates fine. If I fire the button event, the new value gets written to the thermostat. The return packet from the stat triggers the update function, and the level event shows up in notifications with the new value. However the Netlinx LEVEL_EVENT isn't called.

Seems like these bi-directional issues with Duet have been an issue in the past. As a matter of best practice, I always want the internal value to update from the returned packet from the device.

here is a shot of the notifications log...Line 8 is Level triggered after a Send Level, Line 15 from a direct thermostat adjustment.

Have you set the right level count on your virtual device?
