I've just forked the official espeasy code to add MS5611 support. This chip a high resolution barometric/temperature sensor costs around 5-9 USD depending on where you are.
I'm wondering if someone is interested in testing it using MS5611 or more importantly MS5607 as I suspect it should work with the latter but I don't have the chip.
It assumes you are using MS5611 in I2C mode at address of 0x77. There is a possibility of switching the address to 0x76 in configuration. Temperature is in C, Pressure is in kPa. Feel free to increase the number of decimals as this is a high precision sensor.
You can find the code here, I have not opened a pull request.

Let me know if you have any questions or feedback. Again, an MS5607 tester would be welcome
