Project query


#1

Hello; I would like to know if it is possible to connect through the same project of cayenne 2 esp8266 located in different geographical positions (each with its wifi access)
One would read the temperature
The other would show it in a physical display
If possible, I would like some help or guidance on how to channel it.


#2

you want the sensor value from device A to be shown on LCD connected to device B ?


#3

right, that’s the idea


#4

that cant be done currently using cayenne.


#5

You can always share dashboard with a link to location B without need from user to login.


#6

@Agroelektronik he needs to send data from device A (arduino) to device B(arduino), not from one dashboard to another.


#7

I get that, but if its only to display data to another location, then there is no need for dedicated receiving device.


#8

yup but he wants to display on LCD connected to device B.


#9

If the idea is to have a temperature sensor in the physical location A and to visualize it constantly (without accessing the screen of the mobile or the PC) in another location B. For this user an arduino for the temperature probe in A and another arduino for the display in B.
Thank you all very much for your attention.

If the Arduino with the LCD is connected to the internet you could use a GET request to download the data from the REST API. Here are some links for you to go over:
