This is a pretty simple Roku Remote Control that I made for Node-red. Just need to change the IP address to your Roku's. I've added a drop-down menu for multiple TVs, drop-down for inputs, keyword search and some icons.
The following flow will create a dashboard so you remotely start, stop, lock, or unlock your Dronemobile equipped vehicle. You can set schedules and a temperature threshold. I have it set so my Suburban won't start in the morning if the outside temp is above 35(F) and only on weekdays.
You will also need the following API wrapper installed. I did not create the API wrapper and have nothing to do with it.
