A device bridge for use between Alexa and Node-Red.
Using the hosted instance and want to support ongoing hosting costs/ want to support the ongoing development project, donate:
| Alexa Interface | Supported Controls | Example Usage | Useful Links |
|---|---|---|---|
| Brightness Control | 0-100%, increase, reduce, dim | MQTT Out | Any MQTT-enabled bulb/ smart light |
| Channel Control | Any number or name, i.e. 101, BBC 1, Channel 4 | HTTP Out | Any HTTP-enabled endpoint |
| Color Control | Red, Green, Blue, Purple, Yellow etc. | MQTT Out | Any MQTT-enabled bulb/ smart light |
| Color Temperature Control | Warm, Warm White, Incandescent, Soft White, White, Daylight, Daylight White, Cool, Cool White*** | MQTT Out | Any MQTT-enabled bulb/ smart light |
| Input Control | HDMI1, HDMI2, HDMI3, HDMI4, phono, audio1, audio2 and "chromecast" | Yamaha Music Cast Amplifier | node-red-contrib-avr-yamaha |
| Lock Control | Lock, Unlock | MQTT Out | Any MQTT connected Lock |
| Playback Control | Play, Pause, Stop, FastForward, Rewind, StartOver, Next, Previous | Kodi RPC | Http Response Node with Kodi RPC Commands |
| Percentage Controller | 0-100%, increase %, decrease % | HTTP Out, MQTT Out | Fans, AC Unit |
| Power Control | On, Off | MQTT Out | Any MQTT-enabled switch, Socket etc |
| Scene Control | Turn On | Multiple | String together a number of nodes for your scene, i.e. lighting, TV on, ACR on |
| Speaker | +/- volume, set to specific number, mute | Yamaha Music Cast Amplifier | node-red-contrib-avr-yamaha |
| Speaker (Step) | +/- volume, mute | Yamaha Music Cast Amplifier | node-red-contrib-avr-yamaha |
| Temperature Sensor | No commands | N/A | View/ query temperature in any room by voice or Alexa App |
| Thermostats Control (Single setpoint only) | Set specific temp**, increase/ decrease | MQTT Out | Any MQTT connected thermostat/HVAC |
* Scene Control and Thermostat Control cannot co-exist with other capabilities.
** Min/ max temperature range set on Thermostat device at time of creation, bridge will not process commands outside of these values.
*** Color Temperature range set on device at creation (in Kelvin), bridge will not process commands outside of these values.
Note there are 3 component parts to this service:
- This Web Application/ Associated Databases, Authentication and MQTT services
- An Amazon Lambda function
- A Node-Red contrib
At present this skill is pre-production, but I can extend it to you (alternatively deploy the component parts!).
This project is based extensively on Ben Hardill's Alexa Smart Home API v2 project:
- https://github.com/hardillb/node-red-alexa-home-skill-web
- https://github.com/hardillb/node-red-alexa-home-skill-lambda
- https://github.com/hardillb/node-red-alexa-home-skill-web
With the main changes being:
- State Reporting within the Alexa App itself (see screenshots above for examples)
- Upgrade to Alexa Home Skill API v3 (enables Play, Pause, Stop, Volume etc. control)
- Web app/ site upgrade to Bootstrap v4 (with minor UI changes)
- All NodeJS web-app pre-reqs being upgraded to vCurrent
- Remediation of various, depreciated NodeJS/ Mongoose functions
- Move to MongoDB Sessions vs Express Sessions
- API-driven temperature/ value out of range errors
