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.
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.
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.
Here’s a cute new widget from Compulab, makers of my beloved Airtop-PC. A first glance, fit-statUSB looks like a very small USB memory key, but it’s actually a programmable color status LED.
Costing just $12 this wee LED looks like a serial port to the host computer. You can send simple commands to the com port to set its color, brightness, make it sequence, etc.
It’s easy to think of many possible use-cases. I can imagine a rack of gear where a servers process status is indicated by a front mounted fit-statUSB. When a critical process goes down the LED indicates this immediately, without requiring a sophisticated management or monitoring system. Just a few scripts.
Might be fun to play with one (some?) of these one day soon.
About 18 months ago I succumb to my impulsive side and purchased a Belkin WEMOLED Light Starter Kit. That kit included the WEMO interface and two of their Zigbee remote controlled light bulbs. Since I had “grand plans” I also ordered another six WEMO bulbs.
I must admit that I had my doubts about Belkin‘s WEMO offerings, but since the starter kit was just $25 at the time, I thought it worth a try. With just $120 invested in WEMO I sought to revisit remote controlled lights for my office, and perhaps elsewhere in the house.
Jumping ahead in time….I’m very pleased to report that I recently sold that collection of WEMO products to a neighbor, recouping about a quarter of my original investment!
Seriously, that WEMO lighting was some of the most infuriating tech to cross my path in recent years. I cannot believe that a big company would offer such a cheesy product. Continue reading “Ye Ha! NoMo WEMO!!”
Some years ago I installed a MaxSeal pet door into one of the French doors that leads into my home office. This lets Shadow & Gwen wander in and out over the course of the work day. I opted for their dual-flap model, which aims to be more weather-tight. We get heavy rain, and there’s no point in attempting to air condition the back yard.
In general, we’re very happy with the pet door. Where “we” are the two quadrupeds, who like their independence, and the bipeds who don’t want to be pestered about every possible coming or going.
If there’s one complaint I have about the dog door it’s the clatter it makes when it closes. Each flap has six metal clips that swing past magnets embedded in the aluminum frame. This acts as a brake for the flapping action, and holds it closed between ingress/egress events.
Honestly, my experience with Doorbot and its creators was so bad that I can’t help but harbor some animosity toward their operation. Yet, I want to be fair. Design is an iterative process. Perhaps they just need a few iterations on the theme to get to more generally usable product.
On the other hand, the description of the new product seems to be an incremental improvement from DootBot. Jump from 802.11B type Wifi to the more recent 802.11N type. Jump from VGA resolution video to 720p video, the baseline for HD. Abandon push-to-talk audio, ala Nextel of old, for something more akin to telephony. It’s basically a reversal of some of the bad design decisions embodied in the first generation product.
On the other hand, they still seem completely wed to their own “cloud service.” My experience with that was expect massive latency on call setup. Expect video only on occasion. I rarely even had continuous audio. On this basis alone you probably won’t receive that Fedex Express package you’re expecting on the first delivery attempt.
I’ve come to understand that my mistake with respect to DoorBot was expecting the kind of performance that I could more reasonably expect from any standards compliant IP phone. The DoorBot team clearly doesn’t have that sort of experience or appreciate that kind of performance. Even if that’s what separates the tools from the toys. DoorBot is a toy. Nothing more.
When the DoorBell Fon eventually failed I was forced to reconsider the situation at our front gate. I let that situation remain unaddressed for some time, until I eventually stumbled upon DoorBot. When DoorBot failed to impress I reached out to Pat, who kindly provided one of their 8028 SIP Door Phones for me to evaluate.
It has taken some time for me to get around to installing the Algo door phone. I was delayed because I wanted to have a small metal plate welded to to the fence post to create a proper mounting platform for the device.
