I wanted some temperature sensor that can place outside my house, it is simple and not very expensive, which directly integrates with HA would be ideal but not 100% necessary.
I have seen these in Aliexpress, I don’t know if someone has them or if you think they can serve me https://acortar.link/5vbeT2
Thanks for the aid, I am starting with all this and I see good resources in this community
EDIT: Thank you very much for all the answers, it is incredible how fast you have helped me. You have also given me many interesting options to investigate more before making a decision
I use Aqara zigbee sensors—they cost under $20 and measure temperature, humidity, and air pressure. I’ve been using one outside (in a covered location) for over a year with no issues.
The aqara are doing ai pressure as well? What model? I have a dozen or so but can’t seem to get pressure.
This one. (Note that “air pressure” is listed as a special feature.)
Well damn it’s the same type I use. What’s the trick to get it HA?
Using ZHA, it has an entity id of
sensor.[device name]_pressure. I don’t know how it works with Zigbee2MQTT.
I use the round version of the same Tuya temperature sensor in my refrigerator and with Home Assistant. For $4 I wouldn’t hesitate trying one in a protected area outside. As long as it’s not directly exposed to rain or sun it’ll probably work fine.
$4?! Wow I have sonoff knes and I don’t think they were that cheap. Are they relatively accurate?
Seems to be. It reads within 1 degree of a digital refrigerator thermometer.
Do you have a link? I’ve been using the square Aqara ones for years but they are way more expensive than that
Well, the price is 16€. I don’t know when the promotion apply
I’m in the U.S. and it’s $4-$5. Free shipping with a $10 purchase. Surprised it’s so much more in the E.U.
You’re right! I’ve seen the offer and usually they’re just for the first piece, but for that item there are no limits.
If you’ve not ordered from Aliexpress be aware their website is set up to display deep discounts for first time orders by default. Once you log in after your first order the discounts disappear and the prices are much higher.
Pretty crappy business practices, but when a product is 1/4 the price of buying locally, still hard to pass up. For $4 a pop I put leak sensors under every sink and toilet in the house. At the time they were $17 each on Amazon. Also be aware it is very easy to buy a wifi version instead of Zigbee because of the way the website is set up. Many Tuya wifi devices require always on Internet access.
Sweet, thanks!
Well that’s going to be a lot more expensive now (tariffs and all).
I use an Ecowitt weather station and sensors inside and out.
And I use weewx on a Raspberry Pi to publish that data. Weewx also has a mqtt plugin so I created a weather topic and transmit all the sensors onto it.
Then I created all those sensors in HA :)
Unless you’re a weather nerd and wanna go that route there’s probably better ways. I was already using Ecowitt devices independent of my smart home stuff.
A number of esp32 based devices have temp sensors too. Or gpio pins to add a 1wire or 3wire sensor.
The ecowitt sensors last a whole season in battery, and they tend to have really good range.
Ecowitt has been really good. I’ve had my station for two years now. Great equipment.
If you want some honest advice: just use an internet source.
Unless you are a buying a scientific weather station to host at your home, none of the Ali* sensors will withstand what you’re expecting.
Either pay for the real thing and get results, or skip on the cheap junk that will almost certainly die in a few months with no warranty or recourse…just use a close weather station.
For the most part I use SHT-35s with esp chips, although I got the Govee sensors with a base station for our reptile enclosures.
