The return of 433 devices
day 1587 Alex is in touch there are still a lot of devices available on the market operating at a frequency of 433MHz there are still of course operating at a frequency of 315 MHz but they are much less common and basically practically not used mainly these devices are used to make security systems because first of all sensors for example there are 3 doors-then there are additional gateways and therefore it is much easier to integrate them and their reliability is basically quite large because they do not put down almost a battery during operation. Triggering If suddenly it is not necessary it does not occur to get ready triggering does not open the door opens I have on the contrary such sensors for opening doors or windows one I worked for almost three years until the battery ran out But in fact of course the battery is not very complicated The only thing that the setpoint sensor needs to be disconnected replace the battery and when connecting the surface it has a special sensor there which also sends the smart home system information that it has worked during operation for the period of operation completed 103000 data sends triggered so much because he controlled a lot of people in the refrigerator with a camera the second sensor still feels good during operation he completed only 18 thousand sends because he stands at the front door and of course people are much less likely to go out enter the apartment than open the refrigerator the state of the battery of this sensor is impossible to find out without disassembling its because it doesn't send any information about the state of the battery or any additional data at all not about the quality of communication or anything just sends a signal to open a certain code and there is also a different code for closing and therefore in principle you can only determine these two states for example the same ones are in the security alarm Maybe a bigger battery and the transmitter itself is more powerful I also use a lot of wireless switches at a frequency of 433MHz now there are more modern ones already in modern design they are the same design as for transmitters wireless switches that work on zigby in principle and they match the design and wired switches also work on zigby or on Wi-fi basically such wireless switches are used in conjunction with wi-fi switches can bind this wireless switch directly to the wired switch and then when you press the button, the function of switching on/off the corresponding button on the wired switch will simply be performed and the big plus is that there is no Delay you do not need to connect the gateway and the home system and it is much more convenient faster if, for example, 5 from wired then in general it will work almost one hundred percent and there will be no delays and Or for example even if there is a large corridor and there is some kind of house there you can put a wired switch somewhere in the middle on both sides make wireless switches because you can tie it to this wired switch there are up to 8 of these wireless switches For example I have one in the corridor I originally just did so that I tied this wireless switches to this switch and could completely Turn off the light from another room I tried to use wireless switches on zigby But of course they have significantly more problems because they work through the gateway integration with the wi-fi switch not direct At all, that is, it either has to be one manufacturer, but I have this wired switch used to the thuja system, but if, for example, a wireless switch is another one there, let's say Xiaomi or maybe there is an atakara, then of course it will be different ecosystems and, accordingly, even if the universal micro gateway is used, it will still be necessary for us through the smart home system to integrate them which in principle causes a delay And the switches themselves of course They work specific For example okar has of course a construction site so that when you click the button immediately sent signal on But then the function of multiple pressing or holding the button is lost If the function is enabled Or for example there is no way to disable it then you can really send either one signal one click on the button multiple clicks on the button or hold and release accordingly in fact even wireless switches have problems triggering That is, for some reason they can the first time you do not send a signal, it is clear whether it does not fall asleep, or some other problem also exists, in principle, sales are wireless relays that also work at 433MHz even wireless outlets but I don't really use them anymore
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.
