Shutdown server with home assistant

dansharpy

Apologies if this is simple but I'm not very good at coding or understanding APIs! I'm looking to set a curl command in home assistant so I can shut down my repetier server from there. I've got the default command in extcommands.xml so can do it via the web interface and I've read the API documentation. Can someone help me with the correct API URL to send from home assistant to invoke the 'shutdown' command? Thanks in advance

Can your home assistant send local urls? Or are they send from a global web server? The api command would be
action: "runExternalCommand", data: {id: 0}, printer: "slugname"

id depends on position in extcommands in case it is a menu command and not an execute command. execute command would be run  as @execute but requires printer to be online.

Thanks for the reply.

Yes Home Assistant is all locally controlled so can send local curl commands. I had it doing the same thing with octoprint but im trying out Repetier as ive just got another 3 printers.

So if the shutdown command is the first command in the extcommands.xml, then the id is 0? 2nd command is id 1, etc?

So am i right in thinking the url would be:

http://192.168.1.100:3344/printer/api/?a=runExternalCommand&data={id:0}&apikey=xxxx.xxxx.xxxx.xxxx

Is the printer:"slugname" parameter required as its a global command? i.e. shutting down the pi that the server is running on.

Don't forget to urlescape the data and make it valid json. Names must be in quotes so "id" not just id. What I copied was from browser websocket stream where I just executed the command. You can do the same to be sure about the id. slug should not be required for global action.

Ok I didnt know about urlescape so I've just done some reading so I think I know what it means now! So in theory this should be the right URL (obviously with correct API key added and command id checked) :

http://192.168.1.100:3344/printer/api/?a=runExternalCommand&data={"id":0%7D&apikey=xxxx.xxxx.xxxx.xxxx

Edit: not posting with correct formatting, I'll just give it a go and cross everything! Thanks for your help!

http://192.168.1.100:3344/printer/api/?a=runExternalCommand&{"id":0}&apikey=xxxx.xxxx.xxxx.xxxx

only encode the data content e.g. with this one: http://www.utilities-online.info/urlencode/#.YCI20mT0kyo

Ok i see the forum reformats what I enter so guess same with you.

Sorry im still struggling with this and ive tried all the combinations i can think of! This is the command i had set up to shut down octoprint in Home Assistant, does this help with the formatting?

"curl -s http://192.168.1.100/api/system/commands/core/shutdown -d '{\"command\":\"shutdown\"}' -H 'Content-Type: application/json' -H 'X-Api-Key: xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'"

this is exactly as its written in my Home Assistant config.

Repetier

You can test with curl. For me I tested this to work and hope forum leaves it as I wrote it:

curl "http://192.168.1.100:3344/printer/api/?a=runExternalCommand&data={"id":0}&apikey=xxxxxxxxxxxxx"

Repetier

Ok forum change dit again. the & are just & and {"id":0} was urlencoded

Finally got it! for some reason my api key had completely changed! Also used the RESTclient addon in firefox to get the correct curl command. For any one finding this from a search the correct format to use for home assistant curl commands is:

repetier_shutdown: "curl -X GET -i 'http://192.168.1.100:3344/printer/api/?a=runExternalCommand&data={"id":0}&apikey=xxxx-xxxx-xxxx-xxxx'"

All %amp; are just & . Obviously put your correct api key and URLencode the {"id:0"}! Thanks for all your help!
