Connectivity FAQs

Find answers to frequently asked questions related to SiteWorx gateway connectivity.

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 nodes in setback?
As an additional safety feature, lighting nodes maintain occupancy sensing while in setback. This behavior is the consistent for Automatic Setback, Scheduled Setback, Duration Setback and Astronomical Setback.

If the connection between a SiteWorx gateway and the SiteWorx Core Services is severed due to an issue with networking equipment or internet provider when a group is in setback, the group will remain in setback until the connection is restored. When a lighting node in setback detects occupancy, it 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 lighting node is vacated, the lighting node will return to its Setback Level after a 5-minute timeout has passed.

Lighting nodes without occupancy sensors such as the SCN-CLM will illuminate at the Setback Active Level of 100% if the node disconnects from SiteWorx while in setback.
If the internet connection is severed, what happens to lighting energy usage data?
Each lighting node continuously records it's cumulative energy consumption similar to how cars have an odometer that records the cumulative mileage of the car. 

If SiteWorx loses communication with a lighting node, that node continues to measure and store its energy usage regardless of the connection to SiteWorx. 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 communications gap spans more than one 15-minute bucket, the energy usage is allocated proportionally to multiple buckets via linear interpolation.

The proportional spreading behavior appears as a flat line in energy usage charts. SiteWorx knows how much energy was used by the lighting node during the period the lighting node was disconnected, but not how the energy usage was spread across the time interval.

Simply, SiteWorx does not lose the total energy usage under these circumstances but does lose the data's shape (when the energy was used).
