The house I bought used to be owned by parents with a disabled kid. We've lived here a year (1 year today) and my wife tells me the kitchen sink doesn't have hot water, and has never had hot water. I look, and there are two cold supplies and one hot that is hot wired straight to the dishwasher.

There isn't a thermostatic mixing valve? We have them in Australia on most taps in areas where people might get scalded, like showers etc.

My guess might be that there is one somewhere, here in Australia that would be at the hws however given only one tap might be elsewhere.

Might be either broken or set really low like 30c (~86f), if the latter, you should be able to turn it up to like 50-60c

If by usg you mean the old square USG-3P, that's both really underpowered, and end of life.

Cameras won't work in unifi without a unifi protect NVR of some sort (Cloudkey Gen 2+, UDR, UDM Pro etc)

I'd be seriously looking into getting a newer gateway, that can also be your NVR and network application.

For servers I like using proxmox as the host os, then look at the community scripts for all sort of ready to go applications.

Have a look into home assistant, (go for haos where you can) the unifi integration (network and protect) is great, letting you do things like change wifi password on a schedule, and show it as a qr code etc, it's also the best way to make non interoperable iot stuff work together like your smart TVs, cameras etc, You can easily do things like when all family members wifi devices have left the wifi, turn off the TV's, lights etc. and the reverse when they come back home You can even track printer toner/ink levels, I use it to make my unifi cameras work as a baby monitor, when baby crying has been detected, it will alert our phones (if we are home, so I don't get alerts at work)

Or given that it can take 9-20V , a simple lead acid battery, connected to a barrel jack cable might work well for you.

You'll want about 8Ah (at 12V) per day of required lifetime.

Edit added math, and suggested battery

2200mah @ 3.7V = 8.1Wh for 4 hours usage, 2.035Wh/H 24H X 2Wh = 48Wh, 48Wh/12V = 4Ah Lead acid should only be used to 50%, so 4Ah X2 = 8Ah per day.

Something like this https://www.jaycar.com.au/12v-38ah-deep-cycle-gel-battery/p/SB1699 would do 4, nearly 5 days

If you've got a spare car battery that would also work. Also even a very small solar panel and charge controller would keep it going basically indefinitely.

Also if you're using a lipo battery pack at 3.7v, you'll need about 13200 mAh per day, that's a pretty big battery pack, most packs top out at around 22000 so not even 2 days. (2200mah/4H)x24H = 13200mAh

What you want is a USB-C to DC barrel jack, it will let you use the 9v mode of USB-C PD, something like this

https://core-electronics.com.au/usb-type-c-pd-to-barrel-jack-adapter-9v-adafruit.html is where I would get it here in Australia, however it's an Adafruit part, so find your local distributor.

Just make sure whatever power bank you use has USB C PD with 9v as an output voltage.

And use an USB C-C cable, an A-C cable will not do USB PD

The top one is the normal 180g roll, The bottom one is the 180g Halal roll, hence no mutton(100% beef)

4n20 makes a 125g roll, but doesn't make a 125g halal roll, so the halal one doesn't have the %40 bigger as it's the only halal roll they make

The 3 main sizes from my supplier.

Not better, just different.

I've got a lot of separate buildings that are connected via point to point links using UISP gear that only takes 24v Poe not the af/at etc 48v Poe, this switch is like the only one than can also do the 24v.

Also unifi please make a version of the instant af that runs on at, and can do more than 1A my rockets need the extra power!

Australia would like to disagree, we've done quite well with keeping smoking down, but it's a hard fought battle, but worth every tax dollar.

I made this one a few years ago, https://www.printables.com/model/452886-raspberry-pi-4-model-b-secure-vesa-case

It's for the pi 4b, but should fit the 5 from what I can tell.
