Intertechno/wall switch experience with energy saving lamps/LEDs?

---

Hey guys,

I was wondering if anyone of you has experience with wall switches from intertechno (or any other brand supported by pimatic) to switch energy saving lamps?

I’m moving into a new apartment and since I’m quite forgetful, I’d like to switch off any lights, whenever my mobile disconnects from WLAN (e.g. when I leave the house), but I still want to be able to switch the light with the “normal” wall-mounted switches.
So far I’ve discovered that some intertechno switches (e.g. ITL-230 or ITL-1000) might be the best choice, apart from the fact they are listed in supported devices as not suitable for LEDs & Energy Saving Lamps. I still have to buy the lamps but it looks like its very difficult to get non-energy-saving lamps.

Has anyone already realized what I want to achieve?

i use intertechno, but did not switch any led or energy saving lamps yet.
there is a new device from it that will make led compatible.
maybe this is of interest

The ITL-1000 can be used with LED bulbs and Energy Saving Lamps, but the ITL-230 does not support it (LEDs supported if LED-Freund BPM-1504 bypass module is used).
Generally, you should check the Intertechno product pages. Have a look at http://intertechno.at/front/produkte/empfanger/einaus/

@mwittig Thank you, I already had a look at the descriptions but I missed the sentence, that the ITL-1000 is suitable for energy-saving-lamps, even though its in the general description So, my worry was that even with BPM-1054 (the minimum load of 30 watts is thereby halved) a load of 15W is still too much.

Thanks again, I’ll go with the ITL-1000 then in the next two or three weeks

@Marie would be nice if you share your findings

@leader21 Sure, I’ll keep you updated.

First finding: there are no wheels on the ITL-1000 for coding the receiver. But the manual reads “all radio transmitters of intertechno are suitable for switching”, so I’ll try with a free choice code from this table. Given, that roughly 16.7 million codes are possible, maybe the house and unit ID can be just increased to up to 4096? Needs to be tested ^^

It will take some time, because my RaspberryPi is still in another apartment than the walls where the switches will be mounted. Additionally I’m on a business trip for the next 2.5 weeks. (one of the reasons the light should be switched off automatically when I’m not home )

yes, the turn wheel codes from my table are working fine!
i checked them with a wall switch that had those wheels.

if you set up a device in pimatic, enable the pairing mode on the itl and switch the device on in pimatic it will pair fine.

Thanks. I intended to do it the way you proposed. Good to hear that this will work. One less worry.

Short update: sorry for the delay, haven’t been home for a while. Well, I tried to figure out how to connect the ITL-1000 to the existing wall switch.
The wiring diagram in the manual is showing three input wires but my present mechanical switch is only connected to two of them. Right now I don’t get the idea on how to integrate the mechanical switch, so that it doesn’t matter whether I switch mechanically or via radio.

U is the preinstalled bridge (which is labeled as X in the linked manual).

sorry i haven’ read your initial post thoroughly and just see that you want to switch with the common wall switch too.

i guess for that you need the ITL230

but don’t know if this is allowed or technically correct but i would try to do it like in the pic below. if you switch your wall swich, you will power on your lamp. but what happens if you switch on via itl-1000 … or vice versa … ? does it work or will it end in a big bang

If you make it like in the picture below, the lights go on if you switch the wall switch. But you can switch it only off with the wall switch too.
So it gives this matrix:

wall swich  |  ITL-1000  | Lamp
off         |  off       | off
on          |  off       | on
off         |  on        | on
on          |  on        | on

@V1per @leader21 Thanks for the answers and the matrix.

So I got a mechanical “master switch” that overrides any off-command received via radio and the radio will only work if the master is off?
Not what I initially wanted, but given the situation I can put the ITL-1000 in the hallway instead the bedroom, use the built-in timer function (e.g. 2 min) and connect it to the “homecoming rule”, so I have enough time to undress. Later on I could expand it using a motion sensor.

There is no “master switch” because when the ITL-1000 is on you can’t switch it off with the wall switch.
Maybee you can work with a latching relay (german: Stromstossschalter) this relay turns the lamp on with a short elektric impulse and off with a second elektric impulse.
You need than a wall push button (german: Taster) and the ITL-1000 must go high for only a second or so.
Or you use a wireless button like the amazon-buton or 433Mhz like this and toggle the ITL-1000.

Sounds a bit complicated to me. I googled for this kind of relais and they seem to have to be installed in the fuse box? I don’t have an electrical engineering degree
I can set the ITL-1000 to switch on for 2 seconds.

Are you sure? the ITL-1000 manual states the following: “Potential - free switching : (Fig . 2) (e.g . garage door by means of key switch) Remove the connecting wire ( X ) and connect up the line to be switched to the two middle terminals (any input/output).” Sounds pretty much straightforward to me

Then use my second way:

I don’t know the exact input/outputs of the ITL-1000 I have only looked at the wireing-picture from Marie.

But if the ITL-1000 have an Input where you can toogle the switch direcly you have only to use a wall push button were the output goes to this input of the ITL-1000.

or go for the itl230

you just need to connect your switch to the existing wires. that’s all. and you are able to mount the ITL230 behind the existing wall switch (if the wall box is deep enough)

This looks pretty nice and have all what Marie wants.

Well, the ITL-230 does not fit in this setting as Marie needs to switch energy saving lamps. The ITL-1000 can be used with LED bulbs and Energy Saving Lamps, but the ITL-230 does not support it (LEDs supported if LED-Freund BPM-1504 bypass module is used).
