Our X1 DVR simply can’t handle any heat buildup. This is probably largely due to the fact that it lacks any fans and several comments on the Internet seem to indicate that the device is underpowered and thus works harder to handle high-quality audio and video (and as a result it generates more heat). I’m undecided on whether or not the box needs to be replaced. The features are fine and when it isn’t having issues it works very well.
Lately I’ve started to experience the same symptoms of the box overheating even though it’s still outside of the entertainment cabinet and the air conditioner is usually on. This may have something to do with using a different TV, which is directly above a small part of the DVR’s case and perhaps restricting airflow in that area.
Last weekend I attempted to use a very inexpensive USB fan to cool the box. It was very basic; little more than a USB plug and a fan motor. It did actually work but it was on a flexible arm, which generated a lot of vibration and thus a lot of noise. Even though it only cost about $5 it simply wasn’t going to work. I also suspect the fan wasn’t intended for continuous use as I noticed the motor was warm when I removed. I dropped it into a box of unused devices and decided to look for something specifically made for this purpose.
That’s when I found the AC Infinity MULTIFAN S5 on Amazon.com, which appeared to be a much better device for cooling the DVR (and indeed, it is). It features two fans that work from a single USB connection. In addition, more fans can be chained together though I don’t have a need for this capability. They truly are very quiet. The fans have a single switch that can be used to turn them off or to a low, middle and high speed. The highest speed isn’t very loud and the set is much, much quieter than the first fan that I had tried.
At $16 it looks like a good deal and even if I replace the DVR with something better, down the road, I can still reuse the fans with other devices. So far I’m extremely pleased with this purchase.
As part of my recent dive back into home automation I decided it would be cool (and once again practical) to be able to receive an alert that the washing machine has finished washing a load of clothes.
This wasn’t something I blindly jumped into. There is plenty of information on the Web documenting how others have already done this with various home automation setups. As it turns out, at least with our washer, Indigo 6, and an Aeon Labs DSC06106-ZWUS – Z-Wave Smart Energy Switch it can be remarkably easy.
The two modules work great together and I haven’t had any problems since I installed them. I can reliably control the connected lamp for the first time since I added home automation modules to this room.
The module includes two outlets. One is for Z-Wave control and the other is a pass-through to power another non-controlled device. It includes a manual on-/off button as well. In the photo you may notice that the power outlet is installed sideways. This is another side effect of owning an older home. Typically, in a house with a power outlet aligned vertically, both outlets on the module would be perpendicular to the floor. This is intended to free up the other outlet but whether or not this actually happens will depend on the size of the power plug used by another device in the other outlet.
