How is this project holding up? Is it still running and was it accurate?

I too would like to know if you every got this working. I would like to set up the one I have as a gateway as well. I am wanting to log pool temp and PSI data to a database.

I am wanting to setup several BME280/RFM69 sensors in a large area and I was wondering which BME280's to get. I have seen some posts about the onboard voltage regulators causing issues with power consumption.

I have used these before with power supplies and they are pretty good.
BME280 with regulator

These are the ones I am thinking I should get.
BME280 no regulator

I really like this design and looking forward to the final working product. I am interested in this for a project where I need to place multiple temp/humidity sensors in multiple containers and I am looking to design and 3D print a small case that would hold an 18650 battery, Arduino pro mini, RFM69, and temp sensor.

I really like this design as I am looking for a small for factor RFM69 shield. One question how hard would it be to integrate a connection for a DHT22 to be able to have a small temp and humidity transmitter. I need to have about 5 of these setup in different locations sending temp and humidity back to a gateway.
