Nice, thank you for sharing.
Not very surprised about the use of running speed and cadence profile as there is no profile for voltage reporting (battery service can only report a percentage).
Advantage of this sensor is fast and easy installing by the non qualified personal. The sensor is designed for large agriculture facility with many greenhouses where is needed to be controlled temperature and humidity, the atmospheric pressure is for control the motor of air inlet and outlet. With help of the sensor installed outside the greenhouse provide information about positive/negative pressure inside the greenhouse.
Finlay the software read accurate temp/humid value of the Si7021, and only atmospheric pressure of BMP180, the temperature sensor inside the BMP180 is used only by the sensor itself to provide accurate atmospheric pressure measurements.
The sensor can be used also for home automation, and drone applications where is needed correction of the UAV barometric sensor compared to the ground barometric sensor, also humidity measurement can help the pilot to calculate more accurate flying time.

Both need protection (internal or external) from excessive discharge (or excessive charge, and short circuits etc)
That is where our new library to check battery level goes in, we could dream to have an internal mysensor security check of a LiPo battery ! they do so in 'copters
I may pass on that. I'm not used to software glitches having quite so much potential impact, and I don't need to save every gram. But to each their own!

for me the sunny season is too short.
I havn't yet tried to use solar batteries in winter so maybe I have the same problems (despite the fact that I'm living 3 degrees south of you), but I have backup solution for very cloudy winter days - regular battery charger.
Looks awesome. Might be fun to put it outside before your front door on 31th October. Still have a Halloween project on my ever growing bucketlist xd
Blynk is awesome for controlling Halloween projects.
