Use espimatic to send commands to pimatic to switch lights

---

Ok no clue if anyone has created something like this but I am kinda fed up with the 433mhz wall switches I use because they often don’t work (bad reception on homeduino).
What I would like is the following: use the gpio pins on an esp board as a way to let the esp send a signal to pimatic (variable). So I would like to connect my normal wall switches to the esp to let the gpio pins get high or low when operating the switch. When the pin gets high the esp has to send a signal to pimatic so I can switch on my hue lights for example and when the pin gets low it should turn off. Tha last part is simple since this is done by rules and it is already the way it works now with the 433mhz switches. But I don’t know if this is implemented in espimatic or espeasy? I’ve seen the other way round on espimatic with the relay settings but I don’t want to switch relays.

Any ideas?

@djmvt might first want to look into ESPimaticRF

ESPimaticRF is a replacement for arduino/gpio and works through wifi. Just connect a set of sender and/or receiver, set it up and voila. Great app

Raspberry pi -> espimatic master ->ALL espimatic slaves -> send rf

Yeah I know that! And going to use that when I am moving to my new home so I can put the esp somewhere else in the home than the pi. But this is not what I meant: I want the esp to send a command to the pimatic when a gpio pin gets high. To me it looks the same as the relays modus on espimatic but I don’t want to switch relays. I just want pimatic to activate a rule when a gpio pin gets high. And preferably 4 gpio pins that send 4 different commands to pimatic. The rule handling on pimatic is the easy part

@djmvt ah yes i have miss read your post, sorry.

Im not sure if there is a esp sketch to update a variable.

What you probably want is
Wall switch -> power to esp so set a variable -> send to pimatic and react by rules -> turn stuff on/off

I think you have to make a sketch yourself.

Basicly you want to post a variable to pimatic when esp8266 boots(hence, gets power from switch).

You could look i to the source of espimatic to see how the connection is handled with pimatic.

@Gleno0h no that would take too long, also it is a waste of resources since the esp (nodemcu) is capable of doing lots more than that. But thanks for your answer

@djmvt i know… But you asked for it? But then i think you want too much. Anyway, for others, here is a reference as to update a variable through a sketch;

@Gleno0h true that. Well maybe I explained it wrong, let’s make it simpler:

I have 4 contacts, simple open close contacts. I want to connect them to an esp and let the esp send their individual states to pimatic over wifi. In pimatic the state of the individual contact will trigger a rule.

In espimatic the other way round is possible with the relays mode, maybe @koffienl has an idea?

Sorry, not implemented in ESPimatic, you would have to make the code yourself

@koffienl ok thanks then this route stops for me, I do not have the skills to write this code myself.
Thanks for your answer!

ESPimaticRF would be your best option. A tiny ESP can be hidden easily.

@koffienl but espimaticrf is used as a replacement for an Arduino with 433mhz sender and receiver if I understand it correctly? That’s not what I meant. I have an Arduino with homeduino running but the receiving part has always been a bit flakey.

Yes, you replace the arduino on the Pimatic side with a ESP and the ESPimaticRF code. Everything stays the same. But you can extend the RF network by placing one or more ESP’s with ESPimaticRF as node in your home.
You can choose what the extra ESP’s should do (receive RF and send to pimatic, relay RF commands from pimatic or both).
In the room where you have problems receiving RF you simply place an extra ESP with ESPimaticRF and let it resend the received RF signal over wifi to pimatic.
(if you ONLY want to grab RF receive you could intall one single ESP with ESPimaticRF, because RF signals captured by ESPimaticRF nodes are send over wifi directly to pimatic with the pimatic API - for that specific part you wouldn’t need a ESPimaticRF connected to the pi).

@koffienl ok clear! Not the solution I had in mind but maybe it will solve my receiving issues. Gonna try. Thanks!

To be honest, you are trying to do it the hard way, thats why i mentioned espimaticrf. Ive replaced my arduino with 2 esp’s and coverage is perfect, also receiving…

@koffienl haha well I thought it was simple 😂
It was also as a preparation for when we are going to move to our new home but maybe this will work, big advantage is that in this way I can also replace the noisy Arduino USB connection so let’s order a few more esp’s

Have you considered to use mqtt? Probably there are sketches easy to be found that publish the state of a switch to mqtt. Maybe this can be a start

How will you power the esp by the way, as they are in the wall?

I have a similar setup but use mysensors for this. Big advantage is that it is powered from batteries. Penlite or cr2032

i am a big fan of espimatic and espimaticRF!
but sometimes even this great piece of software gets to its limits. maybe you can try espeasy instead.
BUT no warranty for anything
