Cool, another nice person able to help with my programming issues than! ;-)

Well, sure, conceptually they are, but what about drive current,
opto-isolation or not, c/o time, contact layout (MBB, BBM), output
current / voltage rating, inductive load switching tolerance ...
On my charge multiplexer solution (HA + ESP32 + 8 way relay board), not
only have I wired the relays in such a way to prevent the risk of more
than one battery being connected to the charger at any time, I've also
installed a 'soft interlock within the ESP code to also manage that in
software.
I can monitor (and log) the charge current and voltage of each battery
and therefore switch to any outlet that has a battery connected and
switch from it once I see the charger enter the float stage or make it
bad and send a notification if it's not in float mode within 'x' time.

I've tried using one on my 3D printer and it got VERY hot so I went back
to a 40A relay.

Nope. Want another go? (and yes, still ONLY talking physical curtain

Good luck with that!
Or you could use one that is Open Source and do with that what you like. ;-)

The 'this' I'm talking of requires a massive team of people mate. If you
think you can cover all that on your own, may I be your agent and
introduce you to Palus who is to founder of Nabu Casa / HA! ;-)

Again, this isn't about you but 'one'. I'm pretty sure you don't think
that just because someone can put up a shelf that they can (would be
guaranteed to be able to) build a house?

I'm not sure what is being wasted here? the chances are, one ESP32 would
be cheaper than a decent capacitor? If it's not using up components you
already have, how are you going to make the display when you need a new
TV. ;-)
(Oh, and if you need components, I have a large box full I can send you
FOC!). ;-)

So you do want it fully automated then. ;-)

I'm sure you have, as have I with my split unit? However, it's not
'smart' so it is very limiting what I can do with it and I can't log
very much with it.

I'm pretty sure that's not the suggestion re 'Smart' kit so that

On / off. Live indication of it's running mode from anywhere in the
house (or world if I wanted to expand it that far). How often it goes
into defrost mode when offering a/c or de-humidification, how different
settings might impact the running cost, activation / de-activation based
on occupancy etc etc.

I could indeed (FingerBots). But it would be far more subtle to not have
to do it that way. Eg, you could use an ESP32 and a relay board to use a
'volt free' way on interfacing things where you may not have access the
schematic.

You don't want to have features with HA that you probably enjoy with
other things? Logical inconsistency.
I was like that with my Digital Camera versus using the camera on my
phone. Then I noted I had my phone camera with me most of the time, it
gave as good a picture and was already 'connected' to be able to share
or save the pictures.
I'm a bit like that with automatics versus a manual gearbox. That said,
I have had much more variation in use (are rarely 'good') with autos
than I ever have with manuals.
The last was test driving a dual clutch job in a VW where the delay in
it getting itself sorted felt dangerous to us! ;-(

What, you have bypassed the thermal trip AND fuse as well? No wonder you

Yup, built-in safety features. Thermal trips, thermal fuses, stall
detection, air-flow / pressure sensors (filters), run time limits, water
level etc etc.

I set up a BT scanner as part of a proximity detection system and you
wouldn't believe the data I collected! Temperature sensors, mobile
phone, tyre pressure sensors, remote controls (inc car entry) the list
was nearly endless!

No, I wasn't questioning if it works (if obviously does), just wondering

Sure, you have prevented the issue by reintriducing some lubrication.
That's the result I would have expected.

Yup, that's good them, It's ok to nurse these things along, even when

Cool. I bet it's the former. ;-)

That would surprise me very much. Given many things have at least a one
year warranty (even more thanks to the EU). I really can't see many end
users stripping their electric fans down to re-lubricate what should he
a lifetime lubricated bearing, or paying someone to do it?

Yes, because you are 'a living thing' and are impacted by such things.
In the same way my mate has given up running his de-humidifier in the
same room as his two lard fish tanks! ;-)
