I haven't see anything with 0.1°, but the BME280[0] has +-0.5° accuracy and also measures pressure. I have a few DHT22s and find them to be a little bit temperamental (humidity drifts, sometimes won't return a reading) but I've been happier with with BME280 (though I've always used the breakout versions[1] as it looks like a bitch to hand solder). It's an I2C parts and there's support for it in NodeMCU and Arduino so it's easy enough to get started with.
