British Gas Smart Meters

I’m using the Hildebrand Glow meter with MQTT feed into Node Red, can recommend.

Me too. Seems like BG has upped their game with the website now providing real-time usage data. Would love to have this in HA

Yes, same here - would love to have that integration.

Do I understand Display and CAD - Smart meters – Glow from Hildebrand correctly? Does this replace the British Gas display, and add additional features? How do you connect the product to the existing gas/elec installation?
