Request if you order:

If you order, please either use your Bright email account for the order, or add it to the Notes field so we can retrieve your meter details, thank you for your help.

Additional information :

  • Our obligations as a DCC Other User mean that customers whose meters are enrolled in the DCC will have to verify their identity before we can retrieve their data; this is all managed through our Bright App.   We are able to join your Display and CAD to your SMETS meters without your supplier's involvement because we are a SECAS (Smart Energy Code Administrator) approved DCC Other User. Please be assured that your verification data is stored in a separate, secure system and Hildebrand are ISO 27001 Certified.
  • Note that electricity meters update every ten seconds, gas meters typically every 30 minutes; this is the data refresh rate available to customers with one of our CAD devices (and working meters and comms hub!)
  • If your supplier has to replace your meters or communications hub, please contact us beforehand by sending an email to Not all suppliers are following the correct procedure and there is a risk the unit won't work afterwards; by telling us in advance we will ensure this risk is removed.
  • Customers with Octopus' Agile tariff can see the tariff on Bright (needs to be requested).

Additional information specific to SMETS1 variant:

  • SMETS1 variant is only available to customers whose meters have been migrated to the DCC infrastructure (they have been migrated if they were 'dumb' but now being treated as smart by your supplier).
  • For customers who have a Trilliant Comms Hub we are not be able to join the unit to your meters - please contact us as that brand of SMETS1 Comms Hub is proving to be problematic for any devices, not just ours.
  • If you have meters that are enrolled into the DCC and don't want real-time information, we are also able to provide access to your consumption history, updated on a daily basis (half-hourly readings) with our Bright app.
* Local MQTT guidance available here
