@rikki78 should be the its-23 if’m not wrong.
For multiway switches this will work if you disconnect the actual a power supply / wires
to the switches and just add these devices. Then you still need a re receiver like the itl-1000. So you are switching with the common light switches on or off and simultaneously you could switch via pimatic. Please definitely correct me if I am wrong!!
Good receivers for Ceiling light between switch and lamp
@rikki78 should be the its-23 if’m not wrong.
That is a difficult situation if you ask me. The only way I can think off is to replace the wall switches by senders (like these) and install a receiver on each lamp (these for example).
Than you can receive the switches in pimatic and switch the lights in pimatic as well.
Besides you can learn the remotes to the receivers and can use them as well.
I found follow solution but i think i cant get access to the point.
And i found this Switch… this would be the Solution because its using a mechanical Relais. But this is Homematic and pimatic has no Homematic Plugin
So i think i will do it with 2 receivers (each per Lamp) and 3 Transmitters… but i dont replace the standard switches rather i will take off the Switchcovers and make spacers to put 433mhz switches on the top of the old switch.
Just a little Update:
There he is … so cute xD
With this or a Solution like this you have to check and think a lot about it. Why?
This is only a Receiver -> If you switch it with the “Lightswitch” then Pimatic will not know that the Switch is off or on … thats a big problem when you want to Automatic everything with rules
This piece of Hardware can you only use in a little spectrum because you need a “neutral” (blue) in your Lightswitchbox and also you need a enough space to get it in. And it must be just a single Switch for Light nothing more, is there more like 2 Switches or something like that you cant use this thing.
I build me a littte testbench to just check out the device… it looks like that … (not so cute xD)
As pictured here its possible to connect a Light directy to the 300-mini… this is good if you dont want to change your House wiring. Its a option, i want to use in my Hallway … i buy 3 new 433 Lightswitches and 2x 300-Mini to setup the two lights there and mount the 433-Lightswichtes on the top of the original ones.
i do this Testbench just to setup the Button in Pimatic and to check if the Device is working. i check also what would happen if you put this think after switches… the Result if the 300-mini losses his power and gets them back the light will be stay off.
In the moment i have to check a litte bit stuff with the cabling etc… but a bigger Question is how to fix the Problem that you get no feedback from the 300-mini to pimatic.
I want later in the Lamps the new IKEA smart lights … so that i can turn on the light over 433mhz and Dimming the lights over the Smart Lamps.
Anybody know if Phlipps Hue (i hear its similar to IKEA) changes the State in Pimatic when a light is On and the light are switched on by the switch on the Wall? if that lamps changes is state then you can mate Rules to set the 433 Mhz Device everytime on the right State.
thats all for the moment folks
can you please give some more info about your actual wiring? Important is the exact amount (and color) of wires at every switch point.
There must be a way to connect one of the existing RF switches to meet your requirements. I have some similar problems and have something in brain.
I know you don’t want to use WLAN but also this could maybe a solution ?: https://github.com/JanGoe/esp8266-wifi-relay
The 300 mini needs power to work… so it needs the Black / Braun one and the Blue … without that its not able to work.
In my case is there a Blue one but i need Clamp to split them … the next problem is the White Cables from the 300mini do not fit in the Lightswitch… than the next Problem is space… because i have a lot of cables there.
And its Done…
I do it so:
I build the “Trust Smart Home Mini-Einbauschalter AWMR-300” in to the Lamp:
than i get a “Trust Smart Home Funk-Wandschalter, AWST-8800” and buy bigger “borders” for my Lightswitch… because the Switch of the Trust wars bigger then mine. Then remove the original Lightswitch (i must do it so only in this Room … long story…) and setup the new border and new cover for my Power socket and turn the switch perm. on with a Luster clamp.
( Normaly to dont have to remove the original switch… just put between the Trust AWST-8800 and the original switch a little spacer and hot glue it )
Last step is to remove the 4 Screw from the backside of the Trust AWST-8800 to get just the Switch without there own boder. Then i attached the Trust AWST-8800 with hot glue on the new boder.
And setup in Pimatic has Switch with Receiving and Sending. Done!
For the Other Rooms, i will just hot glue the bigger borders to the wall and hot glue the other AWST-8800 Switches with a little spacer directly on the old switch… so that old switch will be turned on and nobody can turn it off.
Why now this way?
Because its hard to get the 300-mini mounted like its made for… you need perfect conditions and its not so easy to remove it later
Without a AWST-8800 Switch Pimatic will never gets a feedback if the Light is on or off when you switch it on the mechanical Switch
The new Methode is easy to remove
