ESPeasy - add a relay

---

hello

how can i control a relay?

in the espeasy list, i didnt find this.

…and, is there anywhere a wiki for pimatic-espeasy?

@noxx Hi, yes, it’s normal switch device.

@wutu
thx, i will try it with “switch input”.

where can i find some pimatic samples (e.g. wiki)?

@noxx http command: http://www.esp8266.nu/index.php/GPIO
Do you think sample config for MQTT plugin?

EDIT:
Btw not necessary in most cases to configure actuators in the GUI. Only if necessary change the default parameters, such as mqtt topic.
After uploading the software can directly control the devices.
Example for GPIO output:
HTTP command: http://<ESP IP address>/control?cmd=gpio,<pin>,1
MQTT: mosquitto_pub -t <sysname>/gpio/<pin> -m 1

@wutu

thx. i can switch my relay with
OFF
http://192.168.1.226/control?cmd=GPIO,5,0

ON
http://192.168.1.226/control?cmd=GPIO,5,1

But how can i read the state of the GPIO Pin in Pimatic ?

Hi @noxx,
if you do not want to use MQTT (sending state and boot state), you can use JSON interface http://espeasy/json.

thx. i see

{"System":{
"Build": 78,
"Unit": 0,
"Uptime": 977,
"Free RAM": 25224
},
"Sensors":[
{
"TaskName": "system",
"uptime": 976.00
},
{
"TaskName": "system",
"freeram": 25448.00
},
{
"TaskName": "Temperatur",
"Temperature": nan
},
{
"TaskName": "Tuer",
"magnetsensor": 0.00
},
{
"TaskName": "Beleuchtung_1",
"state": 1.00
},
{
"TaskName": "Beleuchtung_2",
"state": 0.00
},
{
"TaskName": "",
"": 0.00
}
]}````

so, now i want a button in pimatic, like

{ 
  "id": "light",
  "name": "ESPeasy Beleuchtung 1",
  "class": "ShellSwitch", 
  "onCommand": "http://192.168.1.226/control?cmd=GPIO,5,0",
  "offCommand": "http://192.168.1.226/control?cmd=GPIO,5,1"
}

How can i see the correct state, if i switch from another device, eg my browser ?

JSON show the correct value

{
"TaskName": "Beleuchtung_1",
"state": 1.00
},

Beleuchtung_1 = GPIO 5 on ESP

For MQTT plugin, I made a point by reflecting the external condition at all devices.
In your case, perhaps only periodically reads the status of json.

This is exactly what I was avoiding

Have you a expample (mqtt and json) for me?

@noxx
Only you add MqttSwitch device into config in Pimatic. (or via the GUI in pimatic 0.9).

    {
      "class": "MqttSwitch",
      "id": "switch",
      "name": "Switch",
      "topic": "/espeasy01/gpio/5",
      "onMessage": "1",
      "offMessage": "0"
    }

At this point, all the equipment that is hung on the topic reacts to the status change.
eg. mosquitto_pub -t /espeasy01/gpio/5 -m 1
If you want to even respond to other impulse (http command, rules in espeasy, etc.).
In ESPEasy, for the device check the “Send Data”, the device will send the state to topic at each change. (and at this moment, you must configure the actuator in ESPEasy)
At the same place is an option “Send Boot state” (only dev versions for now)

I do not know what version ESPEasy you have. R93 sending to the topic payload 0/1, the older version 0.00/1.00.

THX thx
I will try it
I use at the Moment R78

@wutu

will not work

    {
      "class": "MqttSwitch",
      "id": "switch",
      "name": "Switch",
      "topic": "/espeasy01/gpio/5",
      "onMessage": "1",
      "offMessage": "0"
    }```

{
  "plugin": "mqtt",
  "host": "127.0.0.1",
  "port": 1883
}

i can switch the GPIO with the Pimatic Button On/Off
But Pimatic cant see the new state if i switch the GPIO with

http://192.168.1.226/control?cmd=GPIO,5,0

@noxx R78 sending 1.00 and 0.00 state.

I had try also 1.00 and 0.00

@noxx
Yesterday I tested it on the R78.

    {
      "class": "MqttSwitch",
      "id": "switch",
      "name": "Switch",
      "topic": "/espeasy01/gpio/5",
      "onMessage": "1.00",
      "offMessage": "0.00"
    }

You got it like this? ESPEasy R78 responding to 1/0, but sends 1.00/0.00.

yes, the same code

i start pimatic, the switch of my ESP GPIO5 is off (ESP GUI / GPIO 5: state 0.00)
i switch the GPIO via http://192.168.1.226/control?cmd=GPIO,5,1
ESP GUI / GPIO 5 shows now state 1.00, but Pimatic show off

If you check on ESPEasy “Send Data”. Look into a serial console. Or mosquitto_sub -d -t /espeasy01/gpio/5 and see whether ESPEasy send data and in what form.

hmm, not good. but mosquitto is installed
