I add a second sensor and add 0 channel widget, but now, channel 2 is working, show measurements all the time, but channel 1 stop showing after a several seconds
i did not understand the above. is it working as you need it or is there still an issue.
I add a second sensor and add 0 channel widget, but now, channel 2 is working, show measurements all the time, but channel 1 stop showing after a several seconds
can you share the code you are using.
/*
This sketch connects to the Cayenne server using an ESP8266 WiFi module as a shield connected via a hardware serial to an Arduino.
The CayenneMQTT Library is required to run this sketch. If you have not already done so you can install it from the Arduino IDE Library Manager.
Steps:
1. Install the ESP8266SerialLibrary.zip library via the Arduino IDE (Sketch->Include Library->Add .ZIP Library) from the Cayenne extras/libraries
folder (e.g. My Documents\Arduino\libraries\CayenneMQTT\extras\libraries) to compile this example.
2. Connect the ESP8266 as a shield to your Arduino. This example uses the Serial1 hardware serial pins available on the Mega. You can also try
using a software serial, though it may be less stable.
3. Set the Cayenne authentication info to match the authentication info from the Dashboard.
4. Set the network name and password.
5. Compile and upload the sketch.
6. A temporary widget will be automatically generated in the Cayenne Dashboard. To make the widget permanent click the plus sign on the widget.
NOTE: This code requires ESP8266 firmware version 1.0.0 (AT v0.22) or later.

the code looks okay. can you share the serial monitor output.

check here all channel 0,1 and 2 are sending data. I would suggest deleting all the widgets and let them repopulate automatically. then click on + to add them.
ok I will try
Great! everything is fine now.
what is Channel 0? could I delete it?
Cayenne.virtualWrite(0, millis());
is it this one? its just counting milliseconds
you can remove it. it uploads the uptime in millis()
Ok thanks.
how could I adjust the refreshing time?
Thank you so much!
Hi. This pictograms on my phone are “soil moisture”. Do you know when will be an update of the app to solve this problem? Thanks
what do you mean by this? can you share a screenshot.
the icon is not yet supported on mobile app. you can select other icon which is supported on both platform.
Ok. Thanks. Have a good day
