When I was 18, it wasn't enough to own a car; I had to "improve" it. A bit of engine tuning, a better radio, the odd go-faster stripe down the side (understated - I was never the full bodykit type). Several decades on and it's now my home I'm tweaking, and I don't just mean redecorating or a bit of standard DIY. I've got a heat pump, solar PV and battery, and an electric vehicle and charger. However, I was always unlikely to leave each element as installed, running independently of the others. With each extra bit of kit installed, I was asking myself how it could benefit from knowing how everything else was running, hence my goal of a single integrated truly "smart" home. Personally, I'm not really interested in a smart home that senses when I enter a room and turns the lights on automatically - the bother of flicking a switch is not a big deal for me - but I'm well aware that may be a valuable function for others. Being able to show Evri or Parcelforce video footage of their delivery driver leaving my parcel in the rain propped up against the wheelie bin (on several occasions) most definitely is important to me, but I couldn't pretend it's as high on everyone else's priortities list. In other words, how the technology in a home is set up and configured should match what the occupants value most. Cue this thread. I've noticed numerous times on the forum that a simple discussion about fixing a problem or preparing for an install has elicited a throwaway comment about some little hack or pearl of wisdom that several others have pounced upon, wanting to know more. This thread is intended to pre-empt that and provide somewhere where any of us can either share tweaks we've carried out that have been unexpectedly beneficial or can ask if (and how) it might be possible to do something they'd like to achieve. All flights of fancy - big or small - are welcome and no configuration rabbit holes are off topic. If the thread becomes too broad, we may well split it into multiple narrower threads but that's a problem for another day. To get things started, here are a few things to ponder. I've come up with my own answers to them but you may want to consider how you tackle them or if you'd want to. The heat pump, the EV and the home battery are three potentially big consumers of imported electricity. If you choose to sign up to a time of use tariff, how do you balance the behaviour of each of those items against each other and against the prevailing import price to best effect? Do you gather information from t'interweb in order to make running changes to any of your kit based on the weather, the weather forecast, carbon intensity of the leccy you import, ad-hoc savings sessions etc.? Is there any single tweak you've made or would like to make that was or could be particularly effective? Is there any other smart kit you have or would like to implement and, if so, could it be (or has it become) something that interacts with your other big ticket items (e.g. if you're already getting a weather forecast, are you using that to do anything "smart" in your garden or greenhouse)? Given how much of this relies on internet connectivity, are you wanting to make changes to your home wifi and/or network in general to make it more reliable? My current quest - and it's most certainly not life-changing - is that I'd like to find a means of measuring the temperature of my wood burning stove's flue. I need that means to be surface mounted (no drilling of holes in the flue), be able to reasonably accurately report flue temperatures up to 350degC (but not break if temperatures exceed that) and be network-enabled so as to report back to Home Assistant. I'm happy with cobbling together with a bit of circuitry and solder but just as happy with a ready-made solution. I am not, however, happy with the £180 price of an Aduro Smart Response box that otherwise does exactly what I want. Over to you all. Welcome to tinkerer's corner and make of it what you will.

@transparent

“the 15kWh battery being discharged at the maximum 100A (5kW) would therefore last 3-hours.”

15kW would only last 2h42m as discharge stops at 10%

better to use dilithium crystals with a matter inverter

@agentgeorge Alternatively …. Use cheapest tariff times to create hydrogen which is then stored in weather balloons in your garage or back garden; later, whilst the peak tariff rates apply, this hydrogen is then converted back into electrical power and … Anon.😉
