@mfalkvidd worked thanks a lot!

Hello,
right know I'm trying to get my Wemos D1 mini configured as Wifi Gateway for pimatic.
I've used this instruction.
https://www.mysensors.org/build/esp8266_gateway
But i get stucked at the verfiy compile step.

I get the following Error during compilation and don't know how to get rid of it:

 error: previous declaration 'void ets_update_cpu_frequency(uint32_t)' here
 void ets_update_cpu_frequency(uint32_t ticks_per_us);
      ^
exit status 1
Fehler beim Kompilieren für das Board LOLIN(WEMOS) D1 R2 & mini.

I've tried the blink example and i also flashed (external) EasyESP.
So the Hardware it self is OK and working.
I know the issue disappears when the MySensors.h get commented out.

Did someone know how to proceed?

Thanks

Thanks for the answer. I tried this and it didn't work. I've started a thread in pimatic forum as well. Maybe they know how to do this.
Thanks

Ok great,
that's what I've done.
But which Node and Child ID is needed for this. So that the Input will communicate as a "Sensor" to the gateway.

Because the Pimatic plugin need to know where to look.

Hello all,
just a question.
Is it possible to add a Sensor (Analog In) directly to a Gateway (arduino) and comunicate this value over USB?

What I want to do is the following:
I've one Sensor which communicate over the Gateway to my Pimatic (over serial USB)
Now I want to add a second Sensor, which is physicaly very close to the Gateway.
So i want to add it there, and it should communicate to Pimatic as well.
Kind of an internal "Sensor" device.

So is this possible? If yes how?

Thanks
