Help me understand my Hot Water!
Discussion
I can't seem to get my head around what's going on here.
New/old house, though I've lived in it for a few months now and haven't tinkered much in here.
As this pic shows, there's a boiler (Worcester Bosch Greenstar 30CDI) which, from the model number, I assume to be a combi boiler.
In the cupboard above, there's a hot water cylinder, labelled MHS Gemini - and the controls look a little like this one: https://manualzz.com/doc/1160551/mhs-boilers-ef500...
The central heading is controlled by a Honeywell Lyric WiFi thermostat, which I can work
It is even integrated into Home Assistant...
But the Hot Water - I've absolutely no idea.
As this next pic shows, the boiler cupboard has some more controls. On the left is this. Presumably the far left white box is the heat link to the Honeywell Lyric, whereas the LCD-screen panel is (I think) only there to control the Hot Water... The danfoss box is, I've Googled, just a wiring box.
There are also what appear to be Aqualisa controls in here for the showers (1 in this room, 1 in an ensuite).
On the right hand side of the cupboard there's this:
Which appears to be a switch for an electric immersion heater, with a handwritten note stuck to it, presumably by the previous owners (who I can't reach to ask, btw)...
Now, I think I saw on the MHS Gemini a switch between 'Summer' and 'Winter' but I've never toggled it, nor can I see from this photo whether it is in 'Summer' or 'Winter' mode.
Anyway... given all of this:
1. Comments from knowledgeable folks - is this a normal / OK setup, or should I be looking at changes?
2. I've recently switched to Octopus energy (and Agile for electricity / Tracker for gas), wondering what's the most efficient way to work with a water cylinder / boiler combo
3. Particularly on the above, is it worth adding any 'smart' tech to make sure my water heats up at the cheapest times
4. What settings should I have that Honeywell LCD on
5. Should I really have the immersion switched to 'On' - and if so, when should I toggle between summer / winter?

Oh, and the Aqualisa showers - they both have dark grey control boxes in here. The showers are 'digital' ones as far as I can make out - they have controls outside the shower enclosure as well as inside. Outside is on/off via a simple button, inside has temperature dial and a boost button.
They look like this, but probably a previous version as the bathrooms were fitted out a few years ago:

Is there any way to get better flow through them easily? Even the 'boost' button doesn't seem to give much 'oomph'.

Ah ok - thanks... so it sounds like "use the Honeywell controls (the LCD) to configure when the H/W in the tank is heated / available, and switch off that immersion switch (which is currently set to be 'on')?
For best efficiency (there's only 2 of us that live here, assume 1 reasonable length shower sometime before 9am daily) what would you usually set the H/W timings to be?
