Hi all,
I wanted to share my recent success in setting up a Raspberry Pi to control my VeraLite system using voice commands. It’s been a fantastic project, and I thought I’d walk through my journey in case others are looking to do something similar.
Getting Started
I started by purchasing a Raspberry Pi and an 8GB SD card. I initially tried using a 4GB card, but it didn’t work out, so I’d highly recommend going with at least 8GB. I used the NOOBS image from the official Raspberry Pi website, which made the setup process much smoother.
Hardware Setup
I connected my Pi to a projector via HDMI, but I ran into an issue where the text-to-speech audio wouldn’t play consistently. After some research, I found that plugging in computer speakers directly into the analog port and running the command sudo amixer cset numid=3 1 resolved the audio output issue. This was a crucial step to ensure everything worked seamlessly.
Software Installation
I followed the guide from Steve Hickson’s blog to install voicecommand. The process involved downloading and extracting the necessary files, then running the installer. One hiccup I encountered was a missing dependency, libboost-regex1.49-dev, which I installed using sudo apt-get install. Once everything was set up, I configured the voice commands to interact with my VeraLite system.
Configuring Voice Commands
In the voicecommand config file, I set up scenes like “watch tv” to turn off all the lights. The key was wrapping the HTTP requests in double quotes to avoid issues with ampersands. For example:
curl “http://…”
This small detail made a big difference in ensuring the commands worked without errors.
Testing and Tweaking
After setting everything up, I tested the system extensively. It’s been running smoothly, and I’m thrilled with how responsive it is. The ability to control my Vera devices through voice commands has really enhanced my smart home experience.
Tips for Others
- SD Card Size: Don’t skimp on the SD card size. 8GB is the minimum I’d recommend.
- Audio Output: If you’re using a receiver, consider direct analog output to avoid audio glitches.
- Dependencies: Always check for missing dependencies and install them before proceeding.
- Command Syntax: Pay attention to how you format your HTTP requests in the config file.
I’d love to hear from others who’ve done similar projects or have tips to share. Let’s keep the discussion going!
