RF wall mounted light switch [discussion]

Thanks for all the feedback! I'm still trying to get a 1-1 solution without gateways etc.

trying to get a 1-1 solution without gateways

This is imho not possible, cause the esp cant receive the rf signals from the switches without additional hardware (and this module is called "gateway" https://www.elv.at/raspberry-pi-enocean-modul.html)

I know, the remote control wall switch would also come with bare receiving circuits that would output 3.3V on one pin. Acting like any other switch input as far as the ESP Easy know.

See attached picture, the receiver units don't need to be enclosed relays. So strip these down and you got what I want.

[moebius]

So you want to use n receivers for n switches instead of only one rf gateway module for all switches?
Then you would need an esp on every receiver location.

[grovkillen]

No I would not, only one esp would actually receive the RF signal. Then it would publish a MQTT message to the rest of the units.

I'm looking for something like this: http://s.click.aliexpress.com/e/c2Hkbfc4 but with a nice looking wall switch. I would like a kit, don't have the money to just buy to try in the dark.

I guess the best would be a i2c receiver that would just publish whatever signal it received, only two pins for multiple switches, but I think that's asking too much as you want the ESP closest to the wall switch to receive the RF. And multiple switches around the house can send to its closest ESP. I don't think a gateway covering the entire house is needed.

With the Kaku plugin you only need a rf-receiver attached to ESP.

Great! I will try that. Thanks for the pointers.
