Recently, I’ve been on a mission to make my home more hotel like. While staying at a hotel, I noticed the lobby smelled really amazing. I thought, hmmm, I could do that.
I purchased a diffuser from aliexpress, specifically one that works with aroma-link app (bt/wifi). The app is riddled with bugs, so I set up a proxy to capture to the apps API calls. I noticed that when the diffuser gets power, it automatically activates, and diffuses scent. So, I thought I’d just control the on/off function and set the diffuser’s internal settings to diffuse for a specified amount of time (you can do this through the device or app). One small modification i did, was rip out that damn speaker that beeps every time the unit powers on.
Here’s the automation thought process:
Turn set hvac fan to ‘on’ to get air circulating (I have an ecobee)
Delay 20 seconds
Turn on diffuser (installed into hvac air exchanger, these connections are included with unit)
Turn off diffuser after 2 mins (done diffusing) (toggle helper switch)
Delay 3 mins (hvac still circulating diffused air)
Set hvac fan back to ‘auto’ (done)
repeat every XX mins.
I’m currently experimenting with concentrations and time of diffusing, but it’s working great! I’ve created a helper toggle to trigger a node red flow that logs in, sends the proper payloads to aroma-link API directly, and controls my diffuser. I can share more details if anyone is interested, but I’d just like to share that it is possible!
This place is smelling amazing!
