Reasonably priced temperature sensors

as my xiaomi gateway does not work with my installation - it was intended to run the temperature sensors i’m looking for alternatives. do you know any reasonably priced sensors, that run properly with hass.io?

Depending on your skill level, you could build you own. I did this a few years back, then wrote up guide on my wiki. They use the ESP8266, and some DHT22 sensors. Connect via wifi, and publish the temperature, humidity and feels-like temperature to an MQTT broker - which is 100% HA compatible. I have 3x of these, and they’ve been in use for over 2 years now, without issue.Total cost, per sensor was about ~$15, depending on where you source your components.

Here’s what I use: Acurite temp (and some w/ humidity) sensors. They broadcast on 433 MHz, are cheap ($10-12), last a long time, and use AA batteries. You can get them here on Amazon or from Walmart w/ a small display for the same price.

I have an “Acurite Bridge” which I got with an old weather station (which has died). I use some software I wrote to convert the messages it posts (which I intercept) into MQTT. The problem is that they want $80 for the bridge (which is insane). However, it’s easier to buy an SDR radio for $25 and then use the RTL-433 library to decode the signals (it supports them). I haven’t actually done that yet but I’ve read about people doing it and I bought the radio, I just haven’t had time to set it up.
