@marceloaqno thank you for the reply, I tried that and I receive "mysGateway: acce[t: Bad file descriptor" Any idea what this means?

I just did a fresh install of pimatic and MsGateway on the pi. But pimatic does not seem to get de messages. i started the gateway via the daemon method, is there a way to see if the sensor is reaching the gateway?

Either its not stated or I cannot see it, but i was wondering... Is this version 2 voor de rPi?
At the moment I am using MySensors version 1.5 with Pimatic as controller. And I would like to use v2.

@Moshe-Livne how did you setup the sensitivity on the senser. I tried your advice, turning it to 0 (all the way to the left) then one stripe back. I pasted it with double sided tape to the top of the machine. Any other tips? I'm thinking of pasting it to the back of the machine.

@Moshe-Livne are you still using this setup? I tried it but sumtimes I get false readings. Like a notification, while the machine wasn't even on...

@Nca78 Did you ever do a project with the ACS 712? I was wondering about this sensor en it's safety.

@Samuel235 Sorry I must have overlooked it, the post has grown. It looks good, AliExpress? Did you ever get the chance to look at those RF switches?

@Samuel235, I hve a much simpler question, What kind of switch are you using? A standaard light switch, did you make a custom one? Could you add a picture?

@BartE (dutch site.. Even better) thanks for the link. I am looking for the safest way, seeing the this will not be in a quick access location. I want to put it away and only return for update/upgrades. But I will also look into an opto-coupler. Thanks for the tip.

@BartE I was wondering about which relay your using. Am I right to understand that your using 230V to switch a 5v pin? I found a signal relay on the internet is that the type you are using? Do you had a link for better reference I could use? Maybe a link with more information about the relay? I can only find sites that want to sell me a relay but not much information about how it works.
