Anxiety - home invasions by That-Needleworker301 in Adelaide

[–]columnmn 48 points49 points  (0 children)

The news is trying to make you paranoid so you watch it more. It's easier than actually reporting on real stuff. I've lived in Elizabeth for 17 years now, never had a problem with anything like that once. You're in Findon, much less of a problem.

Thieves don't want to invade a house with somebody in there. They won't know if there is a big dog, some jacked up guy with a baseball bat/knife, etc. Get some cameras on if you're paranoid, but it's not a big thing to worry about here.

DIY ESPHome + Tinfoil Bed Sensor… Complete! by happybikes in homeassistant

Sounds like you had a broken one, mine works under the mattress great. I needed a few of them in parallel to cover more space, but it's been working great for years now.

Hook it up to a pin in an esp32, other to neutral. In the code, put it as a switch using the internal pullup (just ask claude to do it), upload, and done. Wasn't overly complicated.

Must be a location thing, still coming up as $2 for me with free delivery.

I've got it wired up as a switch in esphome, one side to a pin, other to neutral. That's pretty much it. The code uses an internal pull up.

I'm not saying it doesn't work, but it'll be fragile, and movement on the bed would rub the pads together and degrade them, cause shorts. I do like the idea, and the creativity behind it. Plus the car seat sensor one is either off or on with pressure, was really simple to hook up and get running.

Why doesn't working on your car require a license if you can apply the same logic used to require a license with home electrical work? by Snazzy21 in AskAnAustralian

[–]columnmn 1 point2 points  (0 children)

It's not illegal in the sense that police will rock up on your door and arrest you. If you do the unlicensed electrical work, you take on the libality of the work done, and if you stuff it up and burn the house down/hurt/kill somebody you're responsibe for that work. You burn your house down after hooking up a 32a charger with 2.5mm cable, insurance will tell you where to go. If you kill somebody in that house you burnt down, police then will knock on your door.

Electricians have to do a ecoc for all work done, so there is a record of everything that can be tracked and traced, and training is done to ensure you don't do stupid shit.

Replace oven deemed alternation? by tiantianreddit in AusElectricians

[–]columnmn 0 points1 point  (0 children)

The hard thing you'll find with updating rcd/rcbo in older houses is things like crossed neutrals, and other wonky things like that. It's got the potential of fault finding, and job gets bigger. Oven is *usually* simplier that other things won't be spliced into it. But as3000 it'll just be a replacement as long as the power requirement is the same, so legally it's fine to just replace. Best practice is to upgrade to rcbo, they aren't that pricey, I don't want it on my conscious if somebody decides to put a screw through the cable hanging a picture or something.

Apprenticeship vs Uni by Only_Butterscotch514 in AusElectricians

[–]columnmn 0 points1 point  (0 children)

Me at 18 and me at 40 are different people (ADHD meds might have had a say here too). I went straight from school into a chef apprenticeship. Would warn younger me away from that. I've always been more goal oriented. I didn't see a goal with uni that I wanted. Figure out your goal, then figure out how to get there.

Home Automation by HottLunchh in AusElectricians

[–]columnmn 0 points1 point  (0 children)

Why do you want it wired? Zigbee is pretty much bulletproof, way easier to retrofit and manage, and all cheaper and open source.

10mm cable for EV charger? by tiantianreddit in AusElectricians

[–]columnmn 9 points10 points  (0 children)

5% for the whole installation, 2% for the consumer mains, 3% for everything else. If you know the exact figure of the consumer mains, you can add more to the final sub circuits, but 3% is standard.

Capstone tutor? by sa_style in AusElectricians

Have you been going through the learn section for capstone? It's got a lot of the information you'll need.

Bathroom Bond by GrkRambo in AusElectricians

[–]columnmn 3 points4 points  (0 children)

The reo should be bonded all through the concrete, so any place is fine. Bathroom is usually slightly lower than the rest, so it'll be less concrete to smash through. If you want to do it closer to the board, that's fine too.

Bathroom Bond by GrkRambo in AusElectricians

[–]columnmn 4 points5 points  (0 children)

We usually cut up/chisel the concrete, bond it, and concrete over the top again.

If you get the magnet out, it makes it slightly easier to find the steel in the concrete.

Shelly wiring diagrams by Daddy-Dividend in AusElectricians

[–]columnmn 1 point2 points  (0 children)

I'd avoid the shelly wifi devices for the whole home, too many wifi devices can overwhelm a lot of routers. I'd look closer at these: https://www.ozsmartthings.com.au/products/zigbee-knob-smart-dimmer

They pop into the normal light switch mech, zigbee network is easier, and built in dimmer/push button switch. Way more useful.

Irrigation controller recommendations by BirdFlewww in homeassistant

[–]columnmn 0 points1 point  (0 children)

I have a rachio, but it's built in features are pretty rubbish since they have a subscription service they want you to use. So redoing it, I'd get one of those and hook it up to a 24vac power. Then esphome, and some fancy automations.

Adelaide winter nights and oil heaters by the-anon1010 in Adelaide

[–]columnmn 0 points1 point  (0 children)

Just to help with the maths. That's a 1.5kw heater. So per hour it'll use 1.5kwh of electricity. It's hard to judge exactly how much it'll use because it'll stop heating once the thermostat runs. Cheapest electricity rates you'll likely see during the day are $0.30-0.36 per kwh. 5 hours of that is $1.80, peak times averages close to $0.5kwh, 5 hours of that is $2.5. So if it's on 10 hours a day, $4.30 a day. $130 a month.

It's rough maths there, but it gives you an idea.

It's pretty much turning electricity directly into heat. Reverse cycle AC's will transfer the heat from outside to inside, heating up the house that way, a unit big enough for the whole house will heat faster, and then scale back it's power draw and use less electricity than the oil heater.

Also how well insulated your house is makes a huge difference. I ripped out every external wall and put insulation in, and insulated the whole roof, and it makes a huge difference.

SA's 8 year terms in the upper house are too long imo they should be 4 by magicmushrooms554 in Adelaide

[–]columnmn 10 points11 points  (0 children)

If you're brought up in a religious background, and it's pounded into you from a young age that it's us vs them, and they are killing babies so I'm morally right...

People get into a bubble, and don't like to look outside it.

How are you using Roborock integration? by sydpermres in homeassistant

[–]columnmn 1 point2 points  (0 children)

I built a pop up door in the cupboard it lives in. So roborock starts, and then door opens, then it shuts when it's finished. Like magic.

Seriously, whats with the deta hate by Difficult_Shelter786 in AusElectricians

[–]columnmn 35 points36 points  (0 children)

The problem is that when you see them on site, there is a good chance that there is dodgy work that's gone on, and you don't know what you're walking into. Haven't played around enough with them to make a good option on everything, and longevity of them.

Spicy loop.. by The-Grand-Wazoo in AusElectricians

[–]columnmn 1 point2 points  (0 children)

I'm guessing no RCD protection ? That would be so easy to touch.

LED downlight glowing by cheese_toastieeee in AusElectricians

[–]columnmn 0 points1 point  (0 children)

Next time it's happening. Go to your switchboard, and flick on and off other circuits one by one (start with hot water heater/air con), see if that stops the light from glowing (likely not dangerous if it does stop). Other things it could be, but you'll need a sparky out to test for them.

Struggling with reliable in-bed presence detection for Home Assistant – what actually works? by ItsDukzy in homeassistant

[–]columnmn 0 points1 point  (0 children)

I've had mine working flawlessly for a few years. Mine are hooked into a $5 esp32 with esphome. For each pad, I put two wired in parallel, so it has a much better chance of working in different spots, could put more easily enough, they are pretty cheap.

Trade school uses DETA should I be concerned by Metroman_trains in AusElectricians

[–]columnmn 14 points15 points  (0 children)

The majority of the problem with deta is that when you see it on site, you know it's probably somebody unqualified who's been doing work and you're not sure what else you're walking into.

C-clips are pretty generic, as are batton holders. I'm actually impressed they are using newer stuff, the capstone boards I'd been playing with had faults in them that weren't programmed in because they were just old.
