Thingsboard - Rule chain for exceuting a expression and store its output under a device as telemetry

[mubashirp]

I have a widget in my thingsboard dashboard where i input two values. I need to divide these two dashboard inputs and display it in another widget in the same dashboard. How can i achieve this. Is there any specific rule chain for such applications. Or else is it possible to do it directly in the dashboard.

Hi @mubashirp

In the rule chain, you can catch the 'Attributes Updated' event and perform the calculation based on the two updated attributes.
See the screenshots:

Make sure to change the msgType to "POST_ATTRIBUTES_REQUEST"
