I'm planning to replace the Z-Wave room environment sensors in my home with MotionMote with BME280. This combination will give me the information I would like.
Unfortunately, Felix is out of MotionMote with BME280, so I bought some BME280 from Mouser and would like to add them to MotionMotes that don't have them. I noticed that the MotionMote R3 BME280 pads have some solder build up. I mistakenly thought that if I put flux on the pads and position a BME280 carefully, then heat with a hot air gun, that I could solder the BME280 onto the board. That didn't work.
Does anyone have any suggestions on how to do this?
