Smart Heating (alexa, google assistant compatible)
Winter is coming again, so it's time to revisit my $5 smart thermostat upgrade. I have modified the design to make it work with Google Home and Google Assistant-enabled devices.
Features:
- Complete Google Home integration
- Google Assistant integration
- Web UI with Nest alike interface
- Amazon Alexa compatible
You will need the following nodes:
- node-red-node-smooth
- node-red-contrib-alexa-home-skill -
- node-red-dashboard (for charts)
You will need **Sonoff Basics **buy here:
Settings
- defaultTemp (temperature the thermostat is set to if no temp value is provided)
- ecoL (low temp bracket responsible for displaying the leaf)
- ecoH (high temp bracket responsible for displaying the leaf)
