Reviews of remote light switches in the home

Hello I am looking for opinions on switches that remotely switch on the lights in the house. The functions which such a switch must perform are:
- cooperation with the existing electrical installation
- no additional power supply from batteries
- installation in a wall switch box European standard
- possibility of remote control by radio or a regular switch
- it would be great if the communication was two-way

Here is what I found on the internet. I am building myself a smart home on atmeda and everything is already nicely connected. I have already got the alarm on satel sensors and I still have to solve the problem with switching the light. My question is whether anyone has used it and what is their experience. I am a bit worried about the effectiveness of the radio signal transmission. Question no. 2: maybe someone has a diagram of a device which implements this functionality and can be constructed at home.
What I found on the internet:

http://www.co-co.com.pl/odbiorniki,93.html - interesting solution meets all the assumptions except the last one the disadvantage is that the transmitters are single channel and the transmitter costs over a hundred dollars

http://www.zamel.pl/en,47,0,exta - here, if I am wrong, please correct me. As far as I can see, the receivers cannot be connected in series to a standard switch. It is interesting that the transmitters are 4 channels.

http://www.livolopolska.com/index.php?option=...rt_category_id=114&Itemid=324&lang=pl - the switches look nice and are functional except for the last point, they also support staircase and bistable switches. The disadvantage of this solution is the considerable modification of the transmitter or remote control, but it is manageable. The price looks similar to item no. 1

http://www.deltadore.com/poland/pl/katalog-do...owa/mikro-nadajniki-odbiorniki-sterujace.html A solution similar to the others but expensive. Perhaps better more stable. Maybe someone has experience.

Please correct the links. [Luke]

have you seen mysensors.org ?

I didn't know it, it's an interesting site but I've been through a lot of stages on this site and from what I've been able to find there is no information on the subject that concerns me but thanks, maybe it will come in handy one day

I suggested Atmega and radio because that's where I saw cool ready and programmed circuits with a radio module.
The module is interesting in that it works on 2.4 Ghz at up to 2 Mbit providing a MESH network.
You can easily handle all kinds of sensors, relays, servos etc on this.
Unless you prefer some ready-made switches with a radio module ??
I've seen plenty of these for ridiculous amounts of money on Aliexpress, from glass touch switches to the most ordinary switches with radio control functionality.
Most are so cheap that sometimes it doesn't make sense to make one yourself.

You are talking about a completely different thing than I am What you wrote in the post has nothing to do with my dilemma. So what if you put in a can Atmega with the best written code in the world and the best radio transmitter if the problem is different. I am not an electronics engineer by training, I can tell the difference between a resistor and a transistor and I can correctly connect the elements from the diagram BUT I am not an electronics engineer and I do not know how to construct a circuit which performs the function of switching on a light bulb which is connected in series with a switch in an existing electrical installation. This is the problem with this particular circuit - after all, I have to supply power from the same source to the circuit that sends the signal to the ATMEGI and switches on the bulb. That is why I provided links in the first post and the dilemma is which of the above solutions is the best or possibly my own concept based on some schematic.

I did not understand your train of thought.
I've searched and actually I haven't found such a module in reasonable money either.
The cheapest z-wave is an expense of more than 150 PLN and you will be haunted by the integration (unless you put a controller on a Raspberry)
Of those you mentioned, I can write that the Deltadore modules have an exceptional guarantee of 5 years and a very long range. I have not used the others.

All your assumptions are met by the F&Home Radio system.
Don't be discouraged, the name radio is not authoritative, it is a radio system but can also be wired, also mounted in switchboards or distributed.
The network is not a mesh, and the whole is managed by a server that has several hundred ready-made virtual blocks, or "devices".

Hi thanks for the hint, but I have already come to my own conclusions. I will share them maybe someone will give their comments. I chose LIVOLO because I found libraries on the web that allow you to connect to the arduino. I have not yet tested it. http://forum.arduino.cc/index.php?topic=153525.0 Greetings

Please correct the links in the first post. [Luke]

Zamel is child's play to integrate with AVR's, all you need is the Zamel RXM-01 translator. communication is via 485 in MODBUS, I made it in ASCII. You can also use HR868 module for cheaper and directly from AVR. There are ready-made libraries in Bascom and they even calculate the CRC. I even did more, because I made the control over WIFI from Android. This is what I used the HR868 and ESP8266 for. For android you can write your own software or use the ready made ones there are plenty of them in google play. As for Delta Dore and Elro I have had a bad experience. Apparently simple to use transmission and to that 434MHz, and the range........ This is why I ultimately chose Zamel. Elro has a big plus because it costs 30% of Zamel if you search well in DIY stores As I wrote above, range is an issue. There is a YouTube video of a range test of various systems, Delta, Elro at the grey end
