Gas and electric daily use

I'm just starting to dabble with HA. I have a Shelly current clamp on the feed to the heat pump so I can monitor and separate the heating / hw from the rest of the house load. The shelly app is excellent too.

I built two current clamps using ESP32 boards with a header and a plugin clamp. Total cost of bits was £15 each and I 3D printed my own case. I checked values against a £2k professional clamp and proved it was accurate. Shelly are a good bit more expensive option.

Yes, it was pre heat pump install and we were having a new dis board fitted as part of a kitchen refit so I got the sparky to fit an EM50 into a spare way. I have a Shelly " Pill " it's about the size of a Pill with WiFi and Bluetooth built in. Powered by 5v USB and mine's connected to a couple of temperature probes on the flow and return pipes from the Heat Pump. The Pill is about £7, the probes £3.50 each.

I followed this guide here and bought the bits from AliExpress. Managed to pick up real time voltage from an existing device on the network to give both current and power. The second one is used to keep an eye on what we export to the grid.

The "display thing" is in fact completely separate to the actual smart meter, and can just be turned off and put in a cupboard if you don't like it. It has no effect whatsoever on the data being sent by the meter.

That is precisely what I did on day 1.

Just had a look, seems like current winter use is about £100 leccie, £120 gas a month. Summer was about £80 and £40, all incl standing charges.

Interesting to note a big spike in leccie on Christmas day, presumably cooking the goose!

Solar panels getting fitted next week, hopeful will go down, even in Feb.

We've got 5.25kWp of panels and it's been sunny but cold. 18kW generated today. We have a battery too so that was topped up from solar and the rest exported.
I found the predicted annual generation from the installers to be pretty accurate to what we're actually producing ( I think they all have to use the same data set for predicting generation )

I can’t be bothered with the expense and hassle of getting gas in so the winter months are horrendous for me. This is with just 2 storage heaters plus immerser.

That can’t be right unless you live in castle or very poorly insulated house. If there’s anyway to get solar do it, dehumidifiers are a great way to remove moisture making it quicker and cheaper to heat spaces, I’ve mine on right now and the temp has risen 1c in the last 10mins. We don’t have the cold like Scotland but it is rarely dry here in the SW.

Just got January’s bill through in email. Electricity was £60.38 and gas was £54.57.

Electricity is used for everything except for central heating and hot water where it becomes the responsibility of gas.
