SMETS2 Meter Installed

After being on the Octopus Energy smart meter installation waiting list for 3 months (not helped by Covid-19 working restrictions) the old ‘dumb’ meter was replaced with a SMETS2 smart meter today. A very neat and tidy installation by Privodor who are recruiting and training new installers to help with the backlog. (I don’t know why those meter tails with coloured sheathing, originally installed by SSE, aren’t more widely available / used.)

As expected it had no issues with getting a Telefonica (O2) signal and it commissioned straight away. Once it registers with Octopus I’ll be switched to their Agile tariff.

A pleasant surprise is that the supplied Chameleon IHD6 in-home display had no issues with range (the cabinet is about 15m from the house) and it’s (mostly) picking up a signal in the middle of the house. After enabling WiFi on the IHD6 it’s evident it’s publishing readings using MQTT-in-TLS – but it only seems to be configured to send these direct to Chameleon.

Wind-Driven Ventilator for Vent Stack

In certain wind conditions the drainage system has been getting pressurised slightly via the vent stack for the Biorock sewage treatment plant’s primary tank and lifting the Air Admittance Valves inside the house. The fix for this is to fit a wind-driven rotating ventilator cowl to the vent stack, which ensures that the drainage system stays under negative pressure whatever the wind direction.
