I have an Acurite station, different model. The all in one sensor unit with the rain, wind, and temp measurement is kind of cool, but it doesn't work well, at least for me. I was unable to find a place with clear sky overhead for the rain gauge, clear area around it for the wind gauge, and in the shade for the thermometer. The solar panel and fan doesn't do enough, at least for me in northern California. So, I gave up on the thermometer and mounted it on my roof, where the temperatures are easily 10 degrees warmer than ground level or 5 degrees colder on clear nights.
To deal with this, I've built my own temperature sensor and mounted it elsewhere and send the data via wifi and MQTT. I hacked the acurite driver to accept this data through overcomplicated means. If I were doing it again, I'd use the MQTT drivers that have been developed since I started. Also, I've also had to replace the rain gauge after 8 years of operation. It's become unreliable. We don't get very much rain here, so it might last longer someplace where it's not sitting for 9 months without any rain and being subject to 115 deg temperatures. I don't fault Acurite for this, things wear out. In terms of the barometer, mine is in the display unit, not the sensor. I have no idea how accurate it is. It appears to track my local airport pretty well. What matters for me is more changes in pressure than the absolute value, so if it's off by a couple of percent, it doesn't bother me. Good luck with it!
