Started playing around with and cheap sensors and smart powerplugs (and some , also got some sensors I haven't unpacked yet).

It's been a steep learning curve but it's cool that most of the stuff just works (TP-Link and , Zigbee, (using the Hue Bridge, not directly connected to my Zigbee coordinator). Some stuff this uses the cloud (but can be used locally), other stuff takes out the cloud entirely. (1/2)

Temperature per room
Power usage from Zigbee and ESPhome/WiFi smart plugs.
PIR and door sensor tests (Zigbee)

My bathroom is definitely .

Added in and a for AI/recognition. Still need to mess with that too.

And thanks to I can control/monitor 'smart' devices at my parents and in-laws house as well. (2/2)

holgerschurig,

@yeri Not only your bathroom. It Is said that humidity in houses should be between 40 and 60 percent.

Above 60 the damp water in the air can condensate easy, e.g. at colder room corners. And you can get mold.

Below 40 is not good for your lungs, nose and and throat. The tissue will dry out and makes you more susceptible to infections.

Tip: in the morning, or when outside air is cooler than inside air, open all of your windows fully at the same time. Just for 3 minutes or so. The house won't cool out, but since the cooler air physically can't carry as much water damp as warm air, you reduced the absolute amount of water damp in your house.

We even have a word for this in my language: Stosslüften

holgerschurig,

@yeri Ouch, read that you are in Singapure.

Forget my Stosslüften idea, that won't work probably there. I once was in Singapore, in April. And it rained several times a day, followed by powerful sun and it was very damp outside. And even in the morning it wasn't really cool.

is quite cool in the visualisation as well. It's simple (but at times limiting in the UI) -- but quite simple to put together a . I could connect as well but that’s... for (much) later.

It connects with a wide range of stuff pretty much out of the box

like , , and all the usual smart home suspects. Ordered some devboards to try to build a BLE proxy/repeater for a BLE sensor (https://www.simplysmart.house/blog/bluetooth-proxy-home-assistant-epshome). “kinda works" but range seems to be a problem (even with repeaters) and buttons (the button press doesn't always register) or sensors can be unreliable (no update for a long time)

Re: unreliability. This is the Zigbee map in a small apartment in . The Star light (Ikea bulb) is unplugged, but the Power Plug Blue isn’t... However it has no link/route to the coordinator or another plug (eventhough it's like maybe 10 meters away from routers and the coordinator). Not yet entirely sure why. (1/3)

holgerschurig,

@yeri I have a house with cellar, basement, 1st and 2nd floor. And the floors between those houses are concrete with iron nests in between. A WiFi signal from the basement has a hard time traveling into the 2nd floor, for example.

But somehow Zigbee is super reliable.

The "smart" sockets I have work as repeaters.

On HA's side I have a USB cable, and only then do I have a Zigbee stick. Don't plug the stick in directly, too much computer made RFI. Then one of the older, bulkier smart sockets from IKEA one level above became repeater, automatically. Then another level is the small heating room. And there's another smart plug that controls a "circulation pump". And since 6 months there never was any connection issue, the pump correctly turned on/off by timer. Or via a Zigbee switch on demand. Super reliable for me.
