Could be a poor implementation of Chromecast standard when integrated into the TV's. My Chromecast connected to my TV is also powered by a USB port on the TV. It seems to turn off when the TV is in standby, I have to wait for it to initialize when I turn my TV on. This detail could have been easily lost over the years. I do agree with people who say the Chromecast was best when it first came out. It did one thing wel…

That may be the TV not delivering power to the USB port when in standby

That’s how this Sony behaves

This may not sound bad, but it's the equivalent of 200 kWh per year and the set is only supposed to draw 0.5-1W from the specifications This would cost more than 50 EUR per year at current prices, and is sizeable compared to the average German citizens consumption of 1500 kWh electricity Let's just say this is not ideal given the current energy shortage in Europe...

More than 50 EUR per year at the prices a lot of us contracted for before the war for 2022, to make things clearer.

Right. I'm in Scotland and its closer to £175/year than €50

I’d actually recommend a wifi smart plug with energy monitoring Easier to read the display on your phone ;)

(: guestimates are good enough, everything pales in comparison to the freezer, turn that off and the power bill goes down

Nah they're really not. My freezer is basically nothing because it only gets opened once every few days. You might need a new freezer.

Chromecast doesn't have a power sleep mode right? I e always wondered why especially since it can CEC power on when asked to. Maybe there's a device that I can use to proxy between Chromecast and TV to do this?

I use the chromecast to wake up the TV via CEC. Just starting to play something will turn on the TV.

If only it could turn off the TV instead of showing the wallpapers it would be perfect.

My TV (and everything connected to it) is connected to a power strip which is connected to a HomeKit switchable outlet. When I'm not watching TV the entire power strip is simply turned off. Standby power: 0W

How much power does the switchable outlet itself draw?

That's a good question. I've never measured it... until right now. According to my plug-in power meter, half a watt. Which I think is the lowest amount the meter can display.

It also is illegal in the EU for new devices. https://ec.europa.eu/info/energy-climate-change-environment/... : “Network-connected standby devices Modern appliances are increasingly connected to the internet during standby mode, consuming higher amounts of energy.

There were devices that consumed 80 watts in standby. I have a cabinet full of equipment including my cable modem, a computer (server, no monitor) with 8 mechanical hard drives. The idle current is 76 watts or so. How could something be so high?

You mean idle "server turned on but not used" or completely off ?

Servers usually have out of bands management builtin and that's on all the time, even if management network is not connected. Should be just few watts tho

Not tellies but an interesting look by Dave Jones[of EEVBLOG fame] into how/why simple devices can use up so much power when idle. A lot of it is down to lazy design of the AC>DC circuits

I also put everything except my fridge, freezer, and router on switchable extension cords. Why waste even a single watt-hour on things I don't use?

It feels like over optimization. The base load of my house is around 1kW which is still completely irrelevant in the scheme of how much owning the property costs. The literal cost you’re adding as well as the mental cost of having to switch things on and off all the time shouldn’t be ignored. There’s a timer on the outlets for the soldering gear though, that adds a bit of peace of mind.

Is heating/hot water in that 1.5kW?
