Probably the first way I've done to control a smart home and get some kind of feedback if I'm somewhere outside the house is Telegram. Why do I use Telegram, because in fact the only messenger in which it is possible to make bots normally, and at the same time it is free, and everything works fine, there are a lot of possibilities, you can connect from the smart home system in very simple ways, there is a lot of documentation, it is written how to do it. And that's why it's a very interesting solution, and, of course, I immediately started implementing it. At first, I wanted to make it possible to fully control the smart home through it, but after a while I studied and installed OpenHAB, it also had the ability to create and start different devices, and after that I could get remote access through a special cloud from experienced developers and see all the devices in the smart home, see Their condition was different for different sensors, it was possible to turn on and off different devices, and, of course, it essentially became a telegram. It was not particularly needed, and in principle, the application itself had the ability to make notifications, that is, through OpenHAB it was possible to send various messages to smart home systems, and they would be displayed by the OpenHAB application, which is installed on the phone....

Automation in a smart home should be useful and create additional comfort, but sometimes everything goes wrong… The reasons for this, and how to configure everything, see on my channel.
