Sensibo Sky: The Newest Gadget in my Home Office

It’s that time of year once again, when the mercury rises and I am reminded of how the air conditioner in my home office is so critical to comfort and productivity. This is a little story of how I recently enhanced the now nine-year-old master of cool.

The Fujitsu Halcyon ductless mini-split air conditioner installed here is one of the larger models they make. It’s rated for 30,000 BTU (2.5T if you prefer) which is quite large for the 400 square foot office. It was sized to accommodate a full-height rack of broadcast equipment that used to occupy a corner in my office.

Back when it was installed, it was enough that it did the basics. It kept the space cool and dry, without being noisy. It meets those requirements even today.

The Master of Cool

With no controls on the device itself, it’s operated using a simple IR cordless remote control. The remote functions are very basic; on/off, target temperature, mode (cool, dry, auto) and control of the motorized vanes that direct air flow. I hardly had to use the remote control beyond on/off. Since it’s an IR remote, it only works when pointed directly at the indoor unit.

I can’t fault the Fujitsu air conditioner, since it’s installation we have become more sophisticated users. We’ve had a Nest thermostat installed in the house for years. We’ve become accustomed to the ability to program a schedule of temperature changes to minimize energy use. We also appreciate remote control from our smart phones, whether we’re home or elsewhere. This leaves the mini-split feeling primitive and costly to run.

Sensibo Sky

A few weeks ago I discovered Sensibo Sky, a small IoT device that adds all the remote control flexibility of a Nest thermostat to a split ductless unit with IR remote control. It’s similar to the Logitech Harmony remote control scheme, in that it emulates the IR emitter of the original remote, connecting it to our Wi-Fi, and making it accessible via the web and smart phone apps.

Originally priced at $149, Sensibo Sky initially seemed a bit pricey. I found a recent offer of $99 with free shipping too good to pass up, so I bought one.
