Respect to everyone! Please help below: how do I use this in a function :?
msg.url = "http://192.168.5.144/cm?cmnd=cmnd/sonoff5/Power TOGGLE"
return [msg, msg.url];
Hi and welcome to the forum.
I strongly suggest that you run through some Node-RED tutorials.
The http-request node will do an HTTP POST. It's help panel tells you what format message you need to send it if you want a variable url.
Http request works, I know. But I want to send this in one function. Part of a condition.
(sorry, I do not speak English)
if (msg.payload < 20) {
msg.url = "http://192.168.5.144/cm?cmnd=cmnd/sonoff5/Power TOGGLE"
I've read a lot here on the forum. You are excellent people
Maybe it should be solved differently? Comes with an integer from the dht11 thermometer, if this number is below 20 degrees, please send the said link
So I want to solve this
Perhaps you could post your flow so we can see what its doing ?
A couple of points -
-
Why not use MQTT is a lot easier to manage ?
-
If you want to use the sonoff to control heating etc then you wouldn't use toggle since that could turn the device off it it was already on

Anyway, since I'm sending the data, the point is if x <20 then relay on, else off

This is how I operate a Sonoff S20 device, via MQTT, to turn my external lights on and off.
Basically I just send a msg.payload set to 1 or 0 to the MQTT-Out node.
These are my settings in the MQTT-Out node. Please take note of the 'Topic' setting.
If you are interested, I get feedback from the Sonoff to inform my flow what has happened.
Yes, I would care. Could it be exported? Thank you very much!
Here you go. You will need to edit some of my code to make it compatible with your set-up.
Flow at MQTT-Out sending end.

Thank you for everyone! So it was solved. A DHT11 thermometer connected to esp01 wifi switches a relay as a function of temperature with MQTT. (google translate)
