That is some serious monitoring…..
I love it
what system do you use? 

Yep. It's Home Assistant. Used to control my thermal store and automate heating it via the boiler or immersions along with also turning on all the heating when its cheap as chips.

Have you started to use Grafana to display the data yet ?

As much as I love Grafana (use it a lot at work)  I've not got around to setting it up thus far for my HA data.

£3.29 saved yesterday. We’d had a leak in our bathroom so ran the dehumidifier all day 👍

Nice one! I can't really compare our savings as we did stuff we wouldn't have done otherwise -

- No gas used all day OR this morning thanks to underfloor heating running instead, plus the oil filled rad in the front room
- Dishwasher ran through on a cleaning cycle overnight
- two loads of laundry yesterday including one load of towels tumble dried as well
- Dehumidifier running to off-set the effect of the other washing needing to be dried indoors
- Office underfloor heating on overnight last night to warm the building through out there. (not something we would usually do due to the cost, but if they were going to be paying us...!)
- Oven on yesterday morning for a slow cooked shoulder of lamb which will feed us for several more meals yet

Yesterday was 25kWh which the app shows costs us around 47p, and overnight was another 16kWh which gave us a starting point for today of -7p.  

I did notice though that our weekly costs for electric for the most part until we went on Agile have been £10/£11 recently - last week was about £9, so already showing a win.

We have one of these:

Hi, we just have a manual switch for our immersion, which I'd like to replace - how easy is it to replace the switch yourself for one of these? Just like any switch, or do you need a sparky?

We got a sparky to do it so can't comment on the ease of DIY.

I'm feeling inadequate! No tumble drier, dehumidifier, underfloor heating or any form of home automation beyond a solar iboost: my technological inertia, desire to KISS and dubious CBs have conspired against automation.

Being out Sunday I didn't benefit as much as I might have, but still managed to use 20kWh on Sunday, and not sure yet on Monday morning but the car was at 100%.

One of these weeks I'm going to go over £5 in electricity costs and be severely upset.. :-)   I appreciate granular information when monitoring can help, and there are some seriously impressive examples on this thread but at my level of bills haven't been given the motivation yet!

Looking like some low overnight prices later this week, starting Wed night into Thursday morning. Time to switch the DHW run from daytime (warmer temps + solar) to night time (cheaper Agile slots). I'm still trying to work out the crossover point, but I think anything below ~10p per kWh works out cheaper to reheat overnight allowing for the lower ambient temps. That may change in the middle of winter when overnight temps are closer to freezing.

Since I currently am having to use immersion heating for water I have really been exploiting Agile pricing.

Disappointing overnight pricing tonight, our minimum is 9.93p - was hoping for better than that.
