Turn Your Dumb Air Conditioner Into A Smart Air Conditioner

Recently I moved into a house that has a Diakin mini-split system (FTX12NMVJU / RX12NMVJU) in the bonus room. Mini-splits are known for being extremely energy efficient but unfortunately, I was not able to remotely control the unit on a schedule as I did with my Ecobee smart thermostats, so unless I remembered to manually turn the unit off at night, it would run for no reason. Definitely a first-world problem. I research options Diakin offered. From what I could find, the only option to turn the dumb unit into a smart unit was to by a Daikin Wireless Adapter that required taking the unit apart. Not to mention, the wireless unit cost around $165 so I started searching for other options. Read More

Smart Light Switches

Ever wanted to control a light switch on a schedule? What about turning them on when your Wyze camera detects motion?  Smart light switches are great for automating lights on different schedules, voice commands, and other events such as motion from cameras. Most smart switches work with Alexa, Google Assistant, and IFTTT. If you prefer Siri on iOS, make sure you pick one that supports Homekit. Surprisingly they are affordable at around $20. Read More

Wireless Temperature Sensor

My goal of this project was to track the temperature in different rooms in my house using multiple temperature sensors to send the data back to a raspberry pi and have the data stored historically so I could display it in charts and send alerts. As a follow up to my wireless power outlet project, I wanted to use the 433mhz receiver. I came across some wireless temperature sensors that work over 433mhz. These temperature sensors are great because they are cheap, well built, battery powered and outdoor resistant. I was surprised at how difficult it is to decode the signal coming from the temperature sensors. Read More
