I have used the ESP8266 boards and found that they work, however they can be a pain when they stop working (for unknown reasons - wifi burps or power problems) and you have to power cycle them. I ran the ESP8266 code in my workshop for over two month with no problems, then I put them out in the wild and they failed randomly. I use MQTT to communicate with the RPi running WeeWx and a MQTT broker. I have two ESP8266 talking to a RPi at my vacation home and they both will randomly stop working, when I get to them and power them off and on they work again for awhile (maybe weeks). They don't log problems so I am guessing about the problems. I have an RPi in my workshop basically doing the same function (reading a DS18B20 sensor) and find that having a log and using systemctl to restart on any failure is providing me with a more reliable solution and the cost difference very small. I plan to replace both ESP8266 with RPi's soon. The RPi can easily do much more than read the temp sensors and I am adding a USB camera to one of them, it will FTP an image to the same host as my WeeWx sites. The problems with ESP8266 could be my code is not robust enough for problems - again with no logs its a guess. YMMV
