I've been using the Bright app for a while and with the new local MQTT feature I took the plunge, as my old AlertMe meter readers are slowly drifting in their accuracy. I'm currently with the beleaguered Bulb and while I have no particular complaints, despite their current status, I'm also not against looking around.
I'd like a green energy supplier so far as possible, though I'm realistic about balancing cost at this stage. Also, a provider fully supported by the Glow IHD/CAD is pretty much a given (my Bulb account always shows "Tariff Not Found" for gas in Bright). No electric cars as yet, so no special requirements.
Happy to hear any suggestions!
