Obviously, in the case of refrigerators, washing machines, ovens, thermostats, mattresses, light bulbs, shoes, and even umbrellas that can connect to the Internet, people's expectations for the Internet of Things are inevitable. However, after the experience, the instability and compatibility standards of the Internet of Things technology will eventually be disappointing.
Not a solution for once and for all. For example, various smart thermostats describe the experience as very good: when you turn on the phone, you can turn on air conditioning and heating anywhere in the home. It also learns automatically, such as automatically when you get off work every day. You warm up. However, when you get home, you may face a cold room, then spend hours debugging and don't know when it will fail again. Of course, cases such as smart TVs collecting user data, spot commercials, and unwarranted alarms for house alarms are emerging in an endless stream. This is the first aspect of the IoT device that is not subject to user control.
Second, the IoT device may stop the firmware update at any time. Perhaps the vendor launched an iterative product, perhaps due to its own failure. But obviously, without the support of new firmware, regardless of security, basic functions may also strike. However, no vendor has promised how long the market cycle for this IoT hardware will be. It should be noted that smart sockets and thermostats are not mobile phones. If they do not fail, people will not frequently change them.
The toll trap “Internet of Shit†also pointed out that IoT devices are not just not stable enough and easy to use, and many purchase traps will not actually be written on the box. For example, many security cameras, thermostats need to pay extra to use some advanced features, but if you need to pay $ 5 to set the air conditioning temperature of 25 degrees, is it ridiculous? However, IoT companies need more funds to operate, rent servers, bandwidth, and pay employees, and product prices of tens or hundreds of dollars are often insufficient to keep them operating normally. Therefore, the monthly "advanced account" often becomes a form of insufficient transparency.
In the end, the user may find the room getting colder and colder on a certain day. The original account was not recharged, causing the thermostat to “strikeâ€; the security camera may also stop uploading videos to the cloud space without timely renewals. Once stolen, the loss could not be measured. .
People Need More IoT Commitments Popular IoT devices such as Nest, Sonos, Philips Hue, and Amazon Echo have become increasingly fancy, but they all lack commitment. The Internet of Things devices are not as imaginary intelligence, but they are sometimes very stupid. Using popular language to describe it means “a strike is not consistentâ€. This experience will eventually discourage users from attempting to build an automated home environment, which is extremely detrimental to the entire industry and market.

Pneumatic pick is composed of air distribution mechanism, impact mechanism and pick drill.The impact mechanism is a thick - wall cylinder, in which an impact hammer can be reciprocated along the cylinder inner wall.The end of the pickaxe is inserted into the front of the cylinder, and the rear end of the cylinder is equipped with an air distribution valve box.
There is also a sense of poor experience behind the Internet of Things
The Downstream of China's Instrument Network Meters The Internet of Things boom over the past few years has enabled a large number of emerging technology companies to gain a firm foothold and bring people to the future of the “modern familyâ€. However, IoT technologies are not as convenient and safe as people think, and many times are even a mess. This phenomenon has also triggered some people's dissatisfaction, such as Twitter account "Internet of Shit" (Internet), is a temptation and mocking typical of the Internet of Things inhumanity.
