Simple HTTP post to power on and off

[jakesza]

Hi, I am trying to do a http post to http://esp8266fastled//power=1 or something alike to create a power switch on homebridge by using an http post.

Can you please send me in the right direction?

Hi jakesza,

I had the same issue yesterday sending a HTTP POST request to the wemos. It is not working as you write. It is not working just with the browser. You need to use a tool to create the POST request (I got the hint from a friend). Under Linux you can use curl (you need to use the IP of your device of course (under windows you could search for postman, but I did not use it so far):

curl -d "value=1" -X POST http://192.168.178.92/power

Since I never used homebridge so far, I do not know how to set up there, but it should be similar. If you are interested, I can also explain a basic setup for Node Red, this is currently my construction side ;-).

Good luck, Tobias

Hi Tobias. Thanks for the tips. I need to automate this because currently one has to manually on and off the eap8266webserver. I already use nodered but also cannot automate that into homekit.

I found a plugin on homebridge that can do Http switches just need to figure out how to use it on this.

Here is the http switch

https://www.npmjs.com/package/homebridge-http-switch

To get it working with Node red you could use this:

https://flows.nodered.org/node/node-red-contrib-homebridge-automation

Just googled it. Usuallay to get NR to talk to other services is quite simple. I installed for example the Tasmota plugin and can easly control it via MQTT.

I was running into quite the same challenges and decided to modify the behaviour to use a standard HTTP_GET call for the web-server. This way I can modify (almost) everything with a single HTTP call like e.g. http://esp.address/set?mo=2&pa=3&sp=1000 -> this would set mode (effect) number 2, color palette number 3 and a speed setting of 1000.

The webservers answers with the values being set in JSON format. e.g.: {"currentState":{"wsfxmode_Num":2,"wsfxmode":"Ease Twinkle","state":"on","power":true,"palette_num":3,"palette_name":"RainbowStripe Colors","palette_count":21,"speed":1000,"beat88":1000}}

Power could be set the same way with http://esp.address/set?power=1 (or 0 respectively). (I do automate with fhem, but it should work with homebridge as well.)

Its a heavily modifed version of this code, its grown a lot and has some specifics (i.e. uses DMA for driving the LEDs). Other than that, I have 5 Lamps continously running and automated with this.

I do not know if its appropriate to post that here but if it helps your problem and if you would like to have a look: https://github.com/tobi01001/LED_Stripe_Dynamic_web_conf

This “ Power could be set the same way with http://esp.address/set?power=1 (or 0 respectively).” will def work.

I will try this. Thanks!

curl -d "value=1" -X POST http://192.168.178.92/power

works 💯 Thanks.

Do you perhaps know what the command would be to check the power state?

I now use wled with its android app and the home assistant integration. Works without a lot of config stuff. About your question I need to check later. With /all you can get the state of everything.
