What is giving you (and others) the nerdy temp graphs? I assume some kind of tado/nest smart thermostats on rads in each room? I feel left out.

Looks like Grafana (on HomeAssistant maybe)

That’s it. The central heating control system, Wi-Fi or hardwired thermostats(s) and an app. Mine’s https://www.heatmiser.com/en/
It’s hours of fun for all the family.
See how I opened a window at 7am for a bit of chilly fresh air, then had a shower at 9pm:

A bunch of Sonoff SNZB02 temp/humid sensors sending info to a Tasmota flashed Sonoff ZB-Bridge. I then scrape the temps from that via my own code and present it as Prometheus metrics which are then scraped by Prometheus/Mimir and graphed by Grafana.
About as far from a turnkey/plug-and-play solution as you could get.

Mine is from home assistant. Useful as I have half a dozen different thermometers of different makes.
Can see stuff like this for instance where I have thermostats in my living room and kitchen (fairly stable) and then the loft. I assume that shows something useful but not sure what, guess I'll need to look at a cloudy day and see how much the loft heats up from the house rather than the sun.

Temps around our flat for last 7 days. No heating has been on at all yet (actually, looks like it might have come on at about 6pm yesterday, thermostat is set to 17 deg C.)
A couple of computers in the "study" hence the slightly higher temp there.
(The red line at the bottom is in the shared hallway outside the flat but still indoors.)
We dry clothes inside regularly (the garden is a long schlep) and so we use a dehumidifier. It's modern but not I'm not 100% worried about its efficiency as any inefficiency is just output as heat.
Nothing much else we can do. We have neighbours downstairs and upstairs. If we ever rewire we'll need to pull lots of the carpets/floors up so we'll add some insulation (mostly for sound) that might help a bit. Only one set of windows (living room) aren't double glazed. But essentially it's a big Edwardian house cut up into flats with no real/proper ventilation adjustments.
Good news is that next week should be warmer (highs of 20 deg C at some point in Londonton). Also may have overestimated my gas meter reading back when the price crisis first started - can't do that with Electricity as it's a smart meter.
