Not really a
So I had the bright idea :idea: to setup a mesh network of wireless thermometers in my house using Arduinos (or clones) and RFM69 915MHz wireless transceivers mainly with the intent of datalogging the temperature of the various rooms over time. My primary interest driving this project is to see if I can dial in the HVAC system to keep the temperature more consistent room to room by controlling the airflow to the different vents in the rooms with the manual dampers installed in the system. In order to do that I need good simultaneous temperature data for the various areas of the house.
LowPowerLab has a hardware and software project to make a base gateway that uses a RPi + Arduino (or clone) to be the web interface + logging component. They also have a number of low power Arduino clones called Moteino. Their M0 version can connect the wireless transceiver and their Temp+Humidity+pressure board directly to the back without harnesses or adapters.
To start I only bought the MightyHat kit to use with an RPi3 I already have and one M0 node + sensor to make sure it will really do what I want. If that proves successful I will scale things up. For most of the remote nodes I don't need atmospheric pressure or humidity, so I plan to make them less expensively by using an Anarduino Mini-Wireless boards with the appropriate radio option & a DS18B20 temp sensor. However, a few nodes will have the nicer BME280 sensor so I can monitor the humidity in the garage, basement, and each floor of the house. I don't plan to run from batteries so the slightly cruder hardware design of the Anarduino board that's less suited for battery operation won't be a limiting factor for me.
I'm basically thinking to stick the "ino" board to a wall wart powering it and then plug them in outlets around the house where I want to monitor the temperature. I will make sure the temperature sensor isn't warmed by the wall wart or directly getting blown on by the HVAC registers. Everything basically looks pretty much plug and play and already has the SW developed for this so I won't have to spend a lot of time on the software side trying to make it all work. *fingers crossed*
