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.

[-] AbouBenAdhem@lemmy.world 1 points 4 months ago

This one. (Note that “air pressure” is listed as a special feature.)

[-] a4ng3l@lemmy.world 1 points 4 months ago

Well damn it’s the same type I use. What’s the trick to get it HA?

[-] AbouBenAdhem@lemmy.world 2 points 4 months ago

Using ZHA, it has an entity id of sensor.[device name]_pressure. I don’t know how it works with Zigbee2MQTT.

I use the air quality measurement devices from Air gradient. https://www.airgradient.com/

Really well made and everything is open source. I flashed esphome on it and it works great but a new official firmware version from airgradient has HA support built in.

They have indoor and outdoor devices, I have both.

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.

[-] needanke@feddit.org 2 points 4 months ago

Is the reception in the fridge still reliable?

[-] spaghettiwestern@sh.itjust.works 1 points 4 months ago

Yes for both of my refrigerator sensors. There's a concrete floor and multiple concrete walls between one of the sensors and the hub and it still works perfectly.

$4?! Wow I have sonoff knes and I don't think they were that cheap. Are they relatively accurate?

[-] spaghettiwestern@sh.itjust.works 1 points 4 months ago

Seems to be. It reads within 1 degree of a digital refrigerator thermometer.

[-] RegalPotoo@lemmy.world 0 points 4 months ago

Do you have a link? I've been using the square Aqara ones for years but they are way more expensive than that

[-] peregus@lemmy.world 0 points 4 months ago

Well, the price is 16€. I don't know when the promotion apply

[-] spaghettiwestern@sh.itjust.works 0 points 4 months ago* (last edited 4 months ago)

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.

[-] peregus@lemmy.world 1 points 4 months ago

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.

[-] spaghettiwestern@sh.itjust.works 1 points 4 months ago* (last edited 4 months ago)

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.

Late to the party but I use several from third reality for temp/humidity both indoor and out. They're ZigBee based and I just have a little ZigBee dongle attached to my server. Basically no setup needed once the dongle is up. Just add batteries and then add them in HA.
