Looks like those are curly quote ‘ and ’, instead of '. And it’s missing another ' after the dashboard id.
Here is the modified url before encoding.
javascript:postMessage({action:‘navigate’, route: {path:‘/dashboard/view/xxxxx’}})
And this is what after encoding.
javascript%3ApostMessage(%7Baction%3A%27navigate%27%2C%20route%3A%20%7Bpath%3A%27%2Fdashboard%2Fview%2Fxxxxx%27%7D%7D)
To test out the FKB remote admin page, select Speak Text from the dropdown and just input the whatever text in the field and press Go.
To test the FKB device in SmartThings app, I don’t remember I had to setup a sound. You should be able to press the “Find Sensor” button and the tablet would make some noise.
– EDIT –
To test out the “Find sensor” button, you will need to set the Tone Audio File URL in the settings first. (Tap the three dots button at top-right corner, and tap Settings.)
And here is the test audio file URL I used.
