Looking for advice: Different WANs for different VLANs

Hi all. Thanks for checking in. I've been looking at Routing Rules and Routes to try and solve a couple of problems but I keep screwing up and taking down my whole network (and I've never been more grateful for serial ports).

What I'm trying to do is use different WAN connections for different VLANs/subnets. To begin with, I would like to route my general-purpose subnet (VLAN104) WAN traffic over a Proton Wireguard VPN while leaving all my other subnets using my standard ISP connection. Afterwards, I'd like to additionally route a subnet I use to give my neighbour Internet access (VLAN102) over a different Proton Wireguard VPN. Annoyingly, both the Wireguard VPN connections use the same private IP addresses though I suspect that won't actually matter that much in practise.

I starting to suspect I'm barking up the wrong tree trying to use Routing Rules but I'd appreciate any advice.

My HA Instance is ready to take advantage of some very cheap energy.

The UK is currently experiencing some prolonged windy weather and my all-renewable energy provider offers dynamic pricing. That means cheap energy and even negative-cost energy. This is where my HA instance shines and saves me a fortune on my power bill. Thanks again to the HA devs for this incredible project.

For the curious, I'm using bottlecapdave's excellent Home Assistant Octopus Energy integration via HACS.

For those of us on dynamic pricing, the next 24h are looking rosy.

I'm on an electricity tariff with dynamic pricing. The last week has been pretty rough in fairness, but generally it's really rewarding on most days and sometimes, on days like this, it's amazing.

Based on my past calculations, whenever the cost is below ~20p, I'm paying less for heating than I would with a gas boiler. Where the cost of energy is negative, I'm essentially getting paid to use surplus energy.

Rome knows what's up.

These water fountains flow constantly with fresh drinking water for anyone to use and they are everywhere in Rome. Covering the spout with your finger forces the water out a hole on top, creating a arch of water at perfect 𝓼𝓵𝓾𝓻𝓹𝓲𝓷𝓰 height. The Romans were/are with us.

A mixture of private and social apartments in Wein, Austria

The apartment blocks - two of perhaps a hundred - are surrounded by open greenery, wide walkways and dense tram networks. Most of them have café bars, bookstores, grocery stores or the like on the ground level and loads of benches, play areas and exercise equipment dotted about. The place is rife with Third Places.

The remarkable thing about these is that, to the locals, they seem fairly unremarkable.

Does anyone know a way of calculating the energy needed to heat a home/room?

Does anyone know a way of calculating the amount of heating I need to maintain an average temperature in terms of kWh of heating per 24 hours? Ideally one taking into account weather conditions.

I have a pretty big Home Assistant setup which includes switches for individually controlling all the (electric) heaters in my home. I'm also using an electricity supplier that changes the amount they charge every 30 minutes to reflect supply and demand. Given these rates are published at least 24 hours in advance I can currently choose a number of hours to run the heaters per day and have an automation automatically select the cheapest periods. I'm paying less per kWh for heating than I would if I was using a gas boiler. Plus, it's all from renewables, so working out that number of hours is the next step.
