How to Fix Common Home Automation Problems (Part 1)

It has never been easier to automate a home. Devices are more affordable and, with basic electrical knowledge, you can install smart modules and switches.

However, some problems come up often. In this 3-part series, you will learn how to solve them.

In this first video, I talk about modules that go offline, low-quality routers and access points, 2.4 GHz interference and the importance of a good DHCP server.

Next, I explain why Alexa or Google do not understand some commands and how to solve a common problem: the lack of discrete codes (one code to turn on and another to turn off) on TVs and cable boxes.

Summary of the problems in this part

• Offline module: the cause is almost always the network. Check the 2.4 GHz signal where the module is and whether the router can handle the number of connected devices.

• Router and access points: entry-level models and internet providers' routers tend to struggle with dozens of devices. In an automated home, it is worth investing in quality equipment, with the access points wired by cable.

• 2.4 GHz interference: use channels 1, 6 or 11 and do not place the automation hub next to the router.

• DHCP server: it hands out the IP addresses on the network. If it fails or runs out of free addresses, devices cannot connect.

• Voice commands: avoid generic names such as light, curtain and TV, and choose unique names that are easy to say, such as main light or bedroom TV.

The series continues in part 2 (three-way switching between modules, LED dimming and no-neutral devices) and in part 3 (the provider's modem in bridge mode, Tuya and Sonoff in the same app and garage gate automation).
