How to grep the state of the Tasmota Sonoff?

---

Hi all.

I’m trying to grep the state from my Sonoff using curl, but I can’t figure out how to isolate the state exactly.

The text I’m grepping from

{"POWER":"OFF"}

It is the word ON or OFF i need to isolate, and convert them to small letters.

I have tried using below but it dose not work.

curl --silent "http://192.168.3.136/cm?cmnd=Power"  | grep '{"POWER":"' | cut -d '=' -f2 | cut -c 2- | tr A-Z a-z

Anyone here strong in grep?

Thank you for your help 😊

EDIT: @simonbove I have edited your post to mark the command snippet as code. If the normal HTML format is used straight quotes will be replaced with curly quotes and, thus, pasting the snippet to a command shell will cause errors in most cases. Please see the following topic on the matter for future posts. Thanks!

Hello,
i have it working with this code:
curl --silent http://IP-ADRESS/control?cmd=Status,GPIO,12 | grep 'state' | cut -d ':' -f2 | cut -c 2-

Hi.

Thank you for your reply.

Are you using tasmota firmware in your sonoff?

I’m getting below when trying your url

File Not Found

URI: /control
Method: GET
Arguments: 1
cmd: Status,GPIO,12

Ha,
here you where right.
I have flashed it with espeasy…

Sorry it’s already 6 weeks ago…
Just looked into my Switch device in Pimatic and pasted it into here… Didn’t thought about it…

Yes okay.
But actually, you gave me an idea how to solve it on tasmota.

curl --silent http://192.168.3.136/cm?cmnd=Status | grep 'Power' | cut -d ',' -f5 | cut -c 9-

Gives 1 or 0 for power states

Hello,

i need to change the code for the getStateCommand to:

curl --silent http://192.168.3.225/cm?cmnd=Status | grep "Power" | cut -d "," -f5 | cut -c 9-

i only have changed the ’ to ", because with the ’ i geht the following error in the cmd “cut: the delimiter must be a single character”

@mpuff said in How to grep the state of the Tasmota Sonoff?:

Btw, this is misleading as it also works with single quotes. I have just tested it.
May be you have used another symbol?!

I believe the error you got is from a space or another symbol. I got the same error, and it was because I had put a space by mistake. When I removed the extra symbol (in my case a space) it was working fine with a single quote. But as long as it is working for you, it is great 😁

I just posted my solution to the grep problem, if someone else had the same problem as I had 😊
