xkcd #3109: Dehumidifier
Title text:
It’s important for devices to have internet connectivity so the manufacturer can patch remote exploits.
Transcript:
[A store salesman, Hairy, is showing Cueball a dehumidifier, with a “SALE” label on it. Several other unidentified devices, possibly other dehumidifier models, are shown in the store as well.]
Salesman: This dehumidifier model features built-in WiFi for remote updates.
Cueball: Great! That will be really useful if they discover a new kind of water.Source: https://xkcd.com/3109/

It got hacked and now I’m really, really dry.
I have a rule that “Nothing will be automated that cannot be manually overridden.”
Well, actually it’s my wife’s rule but it’s a good rule nonetheless. As a result, there’s a big panel full of relays in the basement that is the “last mile” for anything climate control or security related.
There have been a few times when it’s been handy. Like when the exhaust fan isn’t working and I don’t want to debug the ESP32 controller today so I just flip it over to “Manual”.
That’s a great rule of thumb. So setup two switches. One for manual and one with a ESP32.
I just bought my first home and as soon as I’m decently unpacked I’m going to start my journey on self hosting.
Currently planning:
- Small i5 HP Pro SFF PC for hosting large apps (going to config for Linux and power it off until I get more mature
- Raspberry Pi4: pihole and home assistant
- Raspberry Pi4: NextCloud, Deck
- ZigBee router thing:
- Nest thermostat came with the house
- adding light bulbs and switches
- want a smart doorknob but the security bothers me. Schlage Connect™ Smart Deadbolt, Z-Wave Plus
- NAS
- Jellyfin
- JBOD on SFF?
- flashing old Netgear nighthawk into wwdrt
- OS Ticket to replace NextCloud Deck for a JIRA type solution to manage projects and major house items.
- ZigBee thermometers for better Nest accuracy
- ZigBee motion sensors for entry ways and bathroom
- smart plugs and motion sensors for basement TV lights
Not sure what else to add. Open to advice or suggestions.
I’ve watched enough Lock Picking Lawyer never to want a consumer ‘smart lock.’ Half of them can be opened with a magnet. Maybe commercial grade is better, but I’ve been locked out of my job after every power failure for the last 10 years, until someone comes along with a physical key.
Re homeassistant on a Pi: homeassistant does a lot of database transactions, so you may want to have db storage on something other than an SD card.
Good call. I was thinking of trying a 128GB usb3 stick I got. Maybe a ssd/nvme on a USB3 controller.
I have an old 2.5inch 500GB laptop HDD plugged into a USB/sata adaptor into my rasberry pi.
that’s been running flawlessly for 3 years and drops every concern with running HA on a pi
I have tentative plans to make my own smart lock by way of electric motor and commercial deadbolts with an RF scanner and a back up battery for emergency. It won’t be amazingly secure in a tech way, but I figure the combination of novelty and DIY should make it reliable.
That said, I gotta be that guy and remind everyone that all locks are security theatre and are not going to protect your house from the persistent or prepared. Your best defense is a combination of foresight and social engineering.
I wish I had setup an identity management system sooner. Been self-hosting for years and about a year ago took the full plunge into setting up all my services behind Authentik. Its a game changer not having to deal with all the usernames and passwords.
In a similar vein, before Authentik, I used Vaultwarden to manage all my credentials. That was also a huge game changer with my significant other. Being able to have them setup their own account and then share credentials as an organization is super handy.
My SO is already using keepass locally. Used to be only a paper notebook. Data breach paranoia.
I plan to setup vaultwarden or keepassXC
If it’s something that’s vital, my mantra is pay to have someone else professional host it.
I’ll pay the $10/year for Bitwarden.
ZigBee router thing:
I’ve been happy with the SMLIGHT SLZB-06M. You can easily flash firmware, and it has PoE which was important for me. I believe it also supports Thread, but I haven’t tried this yet (and I’m not sure if it supports it at the same time as Zigbee).
Zigbee smart plugs from Third Reality have been pretty solid in my experience, and they report power usage.
For circuit breaker level monitoring, I have an Emporia Vue2. I have it running esphome, completely local — unfortunately this requires some simple soldering and flashing, so it’s not turnkey. But it’s been rock solid ever since flashing it. (Process is well documented online.)
I’ve had decent luck with cheap wifi Matter bulbs, but provisioning them is finicky, and sometimes they just crap out and need to be power cycled; Zigbee bulbs (e.g., Ikea) have generally been reliable, though sometimes I’ve had difficulty pairing them initially. After power cycling a Matter WiFi bulb, it takes a while for it to respond to Home Assistant; Zigbee bulbs generally respond as soon as you power them on.
I have a wired smart light switch from TP-Link/Kasa (KS205), and it’s been completely hassle free (and totally local — Matter over wifi). The Kasa smart switch dongles I have work flawlessly but need proprietary pairing, and I’m afraid to update firmware in case they lose local support.
Good luck! Fun adventure :)
Cameras.
Yeah that’s on the list. I want them hard wired though. Gotta hire an electrician to wire up the outside of the house.
if you have a garage, design a method to basically ensure your garage door is closed without you needing to go back to check.
of course if you trust yourself with never making that mistake.
last thing you want to feel is if you remembered to close the door or not and youre already far off
No garage sadly.
I have a controller that plugs right into my opener with a magnetic sensor for if the door is open or not. Running Homebridge I can see it and open and close it from anywhere. Did it all the way from Thailand a while back just for shits and giggles. I gotta see if I can configure it to auto shut if it’s still open at night, have had a couple of whoopsies there.
A camera would work too.
I agree, I set my grandparents doors up on a timer, if its still open at 11 PM it auto closes both doors. I’ve got the ping a few times now saying “emergency door schedule activated” meaning that they were open and had not been closed prior.
