Especially after adding in all the power draw of the automation requires...

What exactly is the incremental power draw for automation? My network gear and server (a little nuc) are sunk power costs as I self host other services.

Idling, my home uses around 100W with the fridge off. One 10W light is an additional 10% of my power budget, and I have a lot more than one light in my house. I also pay about $0.40/kWh.

I can be a bit neurotic about turning off lights when I leave a room, so Home Assistant was a nice way to free up brain space for me. A few motion sensors here and there + some simple automations, and the lights mostly handle themselves. Zigbee sensors and Zigbee or Matter-over-WiFi bulbs, so everything is local. A free VPS+WireGuard setup means I can access them remotely should I need to, with TailScale as a backup.

Cloud failures mean I can't access remotely, but local control is unaffected---if my smart devices stop working it's almost certainly my fault :)

Googling around and one oz (=1 shot as far as I can tell) of espresso seems more like 60mg caffeine.

I'm a little skeptical of the number in the graphic, especially since I don't see a source.

I hate to be that guy, but, "source?" The espresso number "feels" a bit off, and some Internet searching agrees better with intuition:

According to USDA, 1oz of espresso is 63mg and 1C coffee is 92mg.

Just googling around, and both DDG and Google summary report 64mg/shot (with the obvious disclaimer about trusting AI summaries).

Honey is basically bee puke, most folks are ok with that...

In an otherwise healthy person with no other symptoms, there is no significant medical concern.

You're thinking of an "educated bed."

Adjusted for inflation, or better yet something like median salary, would probably be more meaningful.

Seems this will preferentially screw folks in low cost of living areas. If you're in a HCOL/VHCOL area and making ends meet, then a new car is probably affordable. If you're making ends meet in a LCOL area, then this is likely a huge expense.

Matter is also local---provisioning can be a PITA but once done I've been pretty happy with even the cheap Matter WiFi smart bulbs. Home Assistant supports them very well.

Cheap bulbs can be a little buggy, which usually means I need to power cycle some of them now and then.

My lights and motion sensors were obviously unaffected (HomeAssistant). My Emporia Vue2 power monitor would possibly have stopped working, except I flashed it with ESPHome firmware, so it's local only, and of course it was fine. My security cameras (Frigate) were also fine.

If my smart home devices are going to stop working, it will almost certainly be my fault, thank you very much!

There's an interesting discussion in the comments about the architecture: https://www.cnx-software.com/2025/10/20/banana-pi-bpi-r4-pro-board-offers-2x-10gbe-sfp-cages-6x-10gbe-2-5gbe-gbe-ports-wifi-7-support/

Sounds like there are bottlenecks, and you can't run all ports at line speed. User TLS says:

Is it just me, or is the MaxLinear MxL86252C switch connected to one of the 10 Gbps PHYs? The MT7988 only has a single 2.5 Gbps MAC and it’s shared with the second 10 Gbps MAC. It seems like they’re routing a 10 Gbps signal to the MxL86252C, which has two 10 Gbps SerDes interfaces, making the second set of 10 Gbps connected via the switch. This suggests that if the 10 Gbps port is running at full speed, you won’t be able to use the 2.5 Gbps ports.

the audio had glitched so I missed the voice over

This was not a triumph.
