I recently received an ENV4 and hooked it up beside ENV3 to compare pressure readings. There was a substantial difference and when comparing with ipad and local weather service it seems that the ENV4 was reading about 6mbar too low. I read a posts online where other users have observed similar issues with the BMP280 and seems like potentially a driver issue. Possibly this requires a unit library update for the ENV4 module?
