FAQ - SiteWorx Tune

Updated by Curtis Mattoon

If the internet connection at my facility is severed, what happens to lighting nodes?

If the connection between a SiteWorx gateway and the SiteWorx Core Services is severed due to an issue with networking equipment or internet provider, then lighting nodes will continue to operate at their last programmed settings with an active level, occupancy sensor-based timeout, and inactive level until the gateway regains connection to SiteWorx Core Services.

SiteWorx keypads will continue to control nodes on the same network as the keypad that are associated with the keypad button scenes.

If the internet connection is severed, what happens to lighting groups or fixtures in setback?

As an additional safety feature, fixtures maintain occupancy sensing while in setback. When a fixture in scheduled, astronomical, or automatic setback senses occupancy, that fixture will move from the Setback Level to a Setback Active Level of 100%, with an occupancy delay of 5 minutes. When the area below the fixture is vacated, the fixture will return to its Setback Level after a 5-minute timeout has passed.

  • If in a scheduled setback, what happens?
    • If a group is in a scheduled setback and the internet connection is severed between gateway and SiteWorx, the group will remain in scheduled setback until the connection is restored. During that time, fixtures will utilize the occupancy sensors to detect motion and move to the Setback Active level of 100% output, with a 5-minute timeout. 
  • If in an automatic setback, what happens?
    • If a group is in automatic setback and internet connection is severed between gateway and SiteWorx, the group will remain in automatic setback until the connection is restored. During that time, fixtures will utilize the occupancy sensors to detect motion and move to the Setback Active level of 100%, with a 5-minute timeout. 
  • If in an astronomical setback, what happens?
    • If a group is in an astronomical setback and internet connection is severed between gateway and SiteWorx, the group will remain in astronomical setback until the connection is restored. During that time, fixtures will utilize the occupancy sensors to detect motion and move to the Setback Active level of 100%, with a 5-minute timeout.

If the internet connection is severed, what happens to the energy usage data? 

  • If the gateways, lighting nodes, or other SiteWorx devices are still powered, the gateways will continue collecting data and aggregating the data into 15-minute blocks. Once the connection to SiteWorx is restored, the data is transferred to SiteWorx and available for review. 

If gateways are offline, what happens to energy usage data? 

  • If SiteWorx loses communication with a light fixture or DLA for some time, that light or DLA continues to measure and store its energy usage like a car odometer. 
  • When SiteWorx regains connectivity, the data is aggregated into 15-minute buckets. If the previous read's timestamp and the current read are both in the same 15-minute bucket, all the energy is counted in that bucket. If the gap spans more than one bucket, the energy usage is allocated proportionally to multiple buckets. 
  • The proportional spreading behavior looks like a flat line. SiteWorx knows how much energy was used by the light during the period—this is accurate—but not how the energy use was spread across the time interval.
  • Simply, SiteWorx does not lose the energy usage under these circumstances but does lose the data's shape.
