Just an update: Currently using WeeWX version 3.9.1 and Belchertown Skin 1.0rc8 with MQTT. So far everything seems to be tracking. Next to add my additional I2C sensors to the mix. On Tuesday, April 16, 2019 at 10:21:13 PM UTC-4, rich T wrote: > Just an update on receiving Davis Vantage

Luc Not saying there is an issue, but just check it at your end. It could be where I have my SDR/PI and the console set up. During that timeframe we did have very heavy rainfall. Other than that, if you use a BMP280 or BME280 with an offset , the driver tracks with the console. Rich On

[weewx-user] Re: Receiving Davis Vantage weather data with a RTL-SDR dongle Update

Right, but the point is, another driver most likely won't fix it. If it does, please do tell me which. Until then, it's possible to try using a fixed offset to correct the reading and see if it can fix it long term. Such an offset is not unusual with this chip. On Friday, April 19, 2019 at

It's most likely not the driver but the sensor itself. The BMP280/BME280 chips are protocol compatible WRT their common command set, there is practically no room for error when reading out values between the 2. Your chip is probably off. Most cheap modules use chips of unknown origin and I've
