ESP8266 data updation

i made a project for visitoe counter with esp8266.My device esp8266 is detected. but data is not updating even after selecting the proper widgets(Metric).
kindly help me

Greetings @thotakuri, I hope you are doing great.

I’d like to know a few things in order to be able to give you a better support on this matter:

1 - By “My device esp8266 is detected” are you meaning that the device is visible on Ubidot along with its variables, something like:

2 - Ubidots supports two different types of Dashboards: static and dynamic. Which kind are you using? If you are using Dynamic Dashboard, you should double check that you are selecting the correct device from the Device Selector. This is so because when you change the Dashboard’s selected device, the Widget configured to have a dynamic behavior will look for the variable label that you configured, and the current selected device might not have such variable (See below)

In the GIF above, the Dashboard is a dynamic one, and the metric widget is set to have a dynamic behavior. The variable label configured set for this widget is “light-intensity”, which the current device does have. However, when changing the Dashboard’s selected device to another that does not have such variable, the widget can’t display data because there is no data source (no variable labeled as “light-intensity” )

I hope this helps you.

Best regards.
