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 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.
