Any question answered...

^ haha, LFGSS is doing the same as you can see above -

below is the same file, hosted elsewhere

2-bed GF flat, with my partner and 2 children , so it's pretty much on from 8am until 8pm here....ouch!

I haven't bought it yet... and idk if it really matters.

Basically I recently discovered I have BT on my laptop, and I keep meaning to get a small mouse for it anyway, so I've gone down the typical pre-purchase amazon-wormhole and ended up at wireless mice.

I'd rather not have a USB dongle for it, as the main draw for me of a wireless mouse is not taking up a USB slot. Otherwise I may as well just blag a normal mouse from somewhere.

I'm looking at this Logitech M590 in grey as it seems like good value. But part of choosing it is based on the assumption that I can use it without the dongle.

EDIT: Just checking my laptop and it shows the bluetooth as:

HCI Version: 2.1 (0x4) Revision: 0x534f

which I think means it's Bluetooth 2.1 - i.e. too old for any modern BT devices using Bluetooth Low Energy Technology

I was wondering why the first one looked so shit.

Instagram (and LFGSS) presumably re-compress all uploads to minimise storage and bandwidth use. If they even insist on converting PNG to JPG you're probably screwed.

OK so I'm being tight. Thanks for the confirmation ;)

Sorry I phrased my initial reply really poorly. What I meant was that most wireless mice are not Bluetooth despite both using 2.4ghz. A generic 2.4ghz wireless device requires the dongle because it's signal uses a proprietary radio signal and cannot be picked up by a Bluetooth receiver.

The mouse you linked should work just fine without a dongle with you laptop

What do you mean by 'on'? Does your boiler have to constantly be working to keep your place warm, or is it well-insulated enough to maintain temperature for a while?

If it's well insulated, the heating can be 'on' in the sense that the thermostat is set above the outside temperature, but you're not using much gas/electric because heat is retained.

If it's poorly insulated, 'on' means the radiators are all blasting out heat which is immediately leaving the building. I think it also takes a lot more energy to go from cold to warm than it does to maintain a given (reasonable) temperature.

Tl;dr: consider insulation as a factor in the cost of heating, it's as least as important as the thermostat setting.

It's also really fucking cold at the moment, so everyone's using more power for heating than they normally would...

Thanks for the detailed reply.
The house is over 100 years old and poorly insulated and also has a poorly-thought out loft conversion that leaches A LOT of heat.
So yeah...radiators have to be blasting to maintain heat.

It's on my agenda to look into better insulation and definitely try to improve the loft situation as a priority. Who would I speak with about coming to do an audit of sorts?

Cheers.

I checked and my laptop shows the bluetooth as:

HCI Version: 2.1 (0x4) Revision: 0x534f

So it may not support the 4.0 / "Smart Ready" of the one I linked.

You're assuming he has a thermostat; not everyone does. Ours is a dumb system that just has water temp and on/timer/off. Run it only 2 hours a day but that's because I'm an eco nut, frugal, and we're in a middle flat.

My flatmate puts it on constantly, then walks round in a t-shirt - infuriating

I have one of these (M590), it's a good mouse (although it was only £25 when I bought it so maybe worth looking at the price, although it looks like other colours are cheaper).

It's dual function, has bluetooth or a dongle. Both will work, I use it on my laptop via bluetooth so no USB required.

If they're not explicitly described as bluetooth then you'd generally still need the dongle, even if it's theoretically the same frequency.

This is my heating for yesterday. The bars are for when the boiler is on. In these past few days it's been struggling to get up to temperature and keep it there. (Top floor flat in a victorian terrace)

What system do you use that gives you that data?

That's sweet as, the data nerd in me is stirred by these charts. Time to get a smart meter and PiHome

This is really at the limits of my knowledge and I wouldn't trust it at all but I believe there are two types of Bluetooth 4.0/BLE module: one type supports only 4.0/BLE and the other that supports both BLE and 2.x/3.x.

I would however suspect that the mouse has support for only 4.0/BLE and even if it didn't battery life would be impacted negatively enough that you'd end up reaching for the dongle anyway.

Thanks for the feedback.
Actually those don't look so bad as JPG (as long as I keep PS compression setting above 6/12), yet Instagram's (and yes, also LFGSS') algorhythm seems to think this kind of images do ok with being compressed even further (even if they're only as big as 600x600px, 250kb).
It's weird as I can upload other pics at 1080x1080px that are way above 500kb which still look good after they go through their processing..

Netatmo.

It also gives you it in CSV/Excel for those who are really interested.

I think the underlying reason is that previous generations of BT used a fair amount of power, so mouse batteries didn't last long.

Proprietary protocols like Logitech's filled the gap.

Now BT variants use less power so they are more feasible for mice.

Me, I don't get on with anything Bluetooth. Had enough of pairing, unpairing for no reason, re-pairing.

The Logitech stuff just works immediately on sticking it in the slot.

Sneakily turn the thermo valves down

My Netatmo is emailing me warnings that it can't reach target 19.5C.

By which I know that the living room door has been left open to the massive heatsink of the hall/stairs in my draughty semi.

I have an old laptop at home I can test mine with (if I remember to take it home from the office tonight).

Oh believe me I do. He also leaves windows open when he goes out, which is better than mould to be fair, but doesn't adjust the heating to compensate.

I could jam his radiator up to max by unbalancing the valves I guess, so he's uncomfortably hot all the time, then he'll be incentivised to turn the heating off. But I'd be even colder then.

@±ln(x) and @chez_jay - thanks for that. Totally makes sense.

@aggi - no need to test it. From what the above say, it's probably not viable. The grey one is £27 - which is an acceptable colour... and probably helps to locate it. The one I linked is also the "quiet" one, so that might be why it's a little more.

I need to remove the front wheel of a Moulton e-bike. The motor is the in hub. Seems to have a block holding the axel. (See pic)

Any suggestions?
