** The full project description is over at hackster.io. I will have additional details I will be posting here in the near future.

The last few years I have been helping support an enterprise wireless network of 2,000+ access points. It is an interesting, challenging, nightmarish world wireless/RF is. When I started my Arduino adventure it was nice to be grounded in what I was working on. The wires carried all of the data I needed. I just need to make sure the wire was connected, not like those nasty RF signals that bump into other signals that might mess with this or that.

Alas, during my 1st weather project, while I was running back and forth with my data written to a SD card, I thought how much easier this would be if only I could do this with wireless.

In my research, I found information scattered hither and yon, each yielding news clues. I will try and link to those sites (I have remembered and bookmarked) throughout. I will post, what I thought, are the more important bits and pieces.

My requirements are simple. Use a DHT22 to take temp and humidity readings every 5 minutes. Take that data to a central point and log it with the ability to graph and compare it. Initially using USB and a converter for power, moving to own power supply.

** NOTE: I am going to be also working with a BME/P280 to see how to setup and work with I2C on the ESP-01. There are a couple of methods I will point out later on.

I have seen where people use cloud services to keep their data. I have taken this into serious consideration, but am leaning towards a local solution. I have seen one that look promising, Domoticz. It is open source and can be run off of multiple platforms. I have recently received my Raspberry Pi 3 so I am going to try and it get it working there, but that is another day and another post.
