There is Two different pwer state blocks. best to use device node for on and off of most sonoff devices.  
[edit] I recall the power state nodes mainly work with the 4 channel/wall switches sonoff devices.

Power state (read) - read the power state of a device  
power state (write) - to set the power state (on off) of a device.  
device - to turn on off a device  
devices - to get state and info of devices.  
event listener - to listen to events from device in real time

This ewelink node and app work best when not registered to same account, set up 2 accounts and share all devices. One for node-red and one for your app.

Then there is an issue with node or you are suppling wrong object to node, supply an example flow. with example object in inject node.

you need to remove any nodes being used, before you can remove node.Or using console use npm uninstall. If that fails you would have to go into the nodes module folder and delete ewelink files.
