Hi there, I’ve been testing out the weather:bit and have been getting some strange readings from the pressure sensor.

Following this example, I get a value of 27 for the pressure: [https://learn.sparkfun.com/tutorials/mi … d-pressure](https://learn.sparkfun.com/tutorials/microclimate-kit-experiment-guide/experiment-1-reading-the-temperature-humidity-and-pressure). I happen to have a second weather:bit, so tested with it and got the same result. If I remove the “integer / 25600” I get raw values like 705161.

For reference, my local pressure right now is around 1000-1030 hPa.

I’ve found two other posts on here saying they’re getting the same incorrect pressure readings, but I’ve not seen a solution yet.

Any help with this would be greatly appreciated, since we’ve just purchased a few hundred weather:bits.

Okay, after a lot of troubleshooting, I think I figured it out. The v0.0.19 (newest version of the weatherbit extension) is the problem. I’ve got around this by opening the older version (v0.0.12) by using experimental guide’s blocks ([https://learn.sparkfun.com/tutorials/mi … crosd-card](https://learn.sparkfun.com/tutorials/microclimate-kit-experiment-guide/all#experiment-7-logging-to-the-microsd-card)).
