Add power on/off support for Roku TV (Enhancement)

I have a Roku TV (TCL brand) and I’m trying to find a way to turn the power on/off remotely from Home Assistant.

I didn’t see a way to do this in the Roku External Control Guide, but I noticed that the Roku App for iPhone can do this.

I decided to do a packet capture while pressing the key on the Roku App, and here’s what I was able to capture:

......{"request":"key-press","request-id":"12","param-key":"Power"}.M{"response":"key-press","response-id":"12","status":"200","status-msg":"OK"}
.W{"notify":"power-mode-changed","param-power-mode":"power-on","timestamp":"843087.742"}
......{"request":"key-press","request-id":"13","param-key":"Power"}.M{"response":"key-press","response-id":"13","status":"200","status-msg":"OK"}
.Z{"notify":"power-mode-changed","param-power-mode":"display-off","timestamp":"843094.468"}
..%CO.......%CO.......{"request":"key-press","request-id":"14","param-key":"Power"}.M{"response":"key-press","response-id":"14","status":"200","status-msg":"OK"}
.W{"notify":"power-mode-changed","param-power-mode":"power-on","timestamp":"843296.953"}
......{"request":"key-press","request-id":"15","param-key":"Power"}.M{"response":"key-press","response-id":"15","status":"200","status-msg":"OK"}
.Z{"notify":"power-mode-changed","param-power-mode":"display-off","timestamp":"843300.429"}
......{"request":"key-press","request-id":"16","param-key":"Power"}.M{"response":"key-press","response-id":"16","status":"200","status-msg":"OK"}
.W{"notify":"power-mode-changed","param-power-mode":"power-on","timestamp":"843305.781"}
......{"request":"key-press","request-id":"17","param-key":"Power"}.M{"response":"key-press","response-id":"17","status":"200","status-msg":"OK"}
.Z{"notify":"power-mode-changed","param-power-mode":"display-off","timestamp":"843309.832"}
......{"request":"key-press","request-id":"18","param-key":"Power"}.S{"response":"key-press","response-id":"18","status":"202","status-msg":"Accepted"}
......{"request":"key-press","request-id":"19","param-key":"Power"}.M{"response":"key-press","response-id":"19","status":"200","status-msg":"OK"}
.W{"notify":"power-mode-changed","param-power-mode":"power-on","timestamp":"843316.327"}

Is this a function that could be added to the library? Would it help if I did another kind of capture?

Thanks! Roddie

Hello! Could you run this command either right in the root of the project or in a virtualenv with roku installed? Replace X.X.X.X with the IP address of your Roku TV.

python -c "from roku import Roku; Roku('X.X.X.X')._post('/keypress/Power')"

Did that work? Did that power the TV on/off? If so then we can just add Power to the supported methods, otherwise it’s something definitely not available through ECP.

As the user above said, you can power the TV on when it hits that low power state by sending a WOL magic packet to it’s MAC address. Unfortunately, there doesn’t seem to be a great way of doing that without somehow storing the device’s MAC address in a configuration file. I’ve written some scripts for controlling my TV which I plan to publish at some point, if you need some code to look at, but basically what I do to turn the TV on is attempt to send a POST to /keypress/PowerOn with a short timeout (only one second, if the TV is online it will respond almost instantly), and if it times out, I send a WOL packet instead. It’s also worth noting that /keypress/Power is a toggle, while /keypress/PowerOn and /keypress/PowerOff are nifty little functions which will do nothing if the TV is already on or off, respectively.
