Motion thermostat uses an Espruino Puck to send temperature data to a local server so that a device may be switched on once the ambient temperature exceeds the set temperature threshold. The user may flip the puck over (face-side down) to opt to have the fan turned off permanently.
This project utilizes IFTTT webhooks to receive commands to control other devices. For example, I originally started this project in order to control a vent fan that is plugged into a TPLink Kasa IoT plug.
- On the IFTTT website, setup two Web Hooks with the event names: 'puck_on' and 'puck_off'.
- Using the Espruino web IDE, flash the code found in 'espruino-puck-code.js' to the Puck.
- Clone this repository on your choice of server. I opted to use a Raspberry Pi 4 running Ubuntu 20.04. However, you may use any computer compatible with Node 14+ and the @abandonware/noble library:
$ git clone https://github.com/boomninjavanish/motion-thermostat.git
- In the newly created directory, install any node packages:
$ cd motion-thermostat
$ npm install
- Add the following environmental variables via the command line. Be sure to replace the x's with your Puck's mac address and the key found in the IFTTT API URL prefix:
$ export PUCK_ADDRESS=xx:xx:xx:xx:xx:xx && export IFTTT_API_KEY=xxxxxxxxxxxxxxxxxx
- Run the node script:
$ node motion-temperature --verbose
If the output looks like this, you were successful:
[2021-04-05 06:21:14] - battery: 2.8v, fanOn?: false, temp: 20.8
After testing, the script may run like a service using
systemd unit files,
launchd,
node-windows, etc.
Make sure to leave out the --verbose flag to reduce the amount of chatter in your log files.
