To securize use MQTT password !

Cheers !

Hi, great solution!
I have one question: where i should configure MQTT and HTTP param?
Best Regards

Hi there,

I'm a little confused what needs to be changed to make this work?
In the domoticz virtual switch, what http commands do you set for ON and OFF?

Thanks

[dalecooper]

hi there, got the arendst sonoff firmware to work with Domoticz.
This is what I did:

- added MQTT client gateway in Domoticz Hardware (for some reason not all values are loaded in the dropdown box sometimes, so you might have to refresh the hardware page)
- in user_config.h: edit the STA_SSID1 + STA_PASS1 for your wifi settings. +

Code: Select all

  #define MQTT_HOST            "192.168.xxx.yyy"     // [MqttHost] your domoticz ip here
  #define MQTT_PORT            1883         // [MqttPort] MQTT port (10123 on CloudMQTT)
  #define MQTT_USER            ""  // [MqttUser] Optional user
  #define MQTT_PASS            ""  // [MqttPassword] Optional password

- uploaded the arendst sketch to the ESP chip through an Arduino Uno. (see his wiki + make sure to put the esp in flash mode with the button down on startup)

Also, i checked the ESP settings via http in the configuration tab and entered them again + reboot.


So now my christmas lights shine bright as soon as i open the front door

Any idea on how to get the son off telemetry data into Domoticz, like Temperature & Humidity?

Thanks for any ideas!

Hello, can someone help me with this please?

I successfully flashed a Sonoff (with https://github.com/arendst/Sonoff-MQTT- ... uino/wiki/), and it is connected to my Wifi and MQTT server (just local install of Mosquitto not running Node-Red as I don't see why it would be needed in this case)... but it only works if I use the sonoff (webserver or button) to activate the switch.

No matter what I try I can't get the Sonoff to be controlled by Domoticz.

Eg.

I'm monitoring Domoticz/out and /in, I can see the messages being sent by the Sonoff and Domoticz... but the Sonoff never changes state even though Domoticz is publishing in /out the sonoff never reacts.

But if I toggle on the Sonoff I see the messages in /out and /in, and Domoticz updates the state as well (obviously).

I'm stumped.

Out from Domoticz:

Code: Select all

{
   "Battery" : 255,
   "RSSI" : 12,
   "description" : "",
   "dtype" : "Light/Switch",
   "id" : "000140A8",
   "idx" : 88,
   "name" : "Kitchen Cab LED 2",
   "nvalue" : 0,
   "stype" : "Switch",
   "svalue1" : "0",
   "switchType" : "On/Off",
   "unit" : 1
}

In from MQTT (only when executed by the sonoff):

Code: Select all

{"idx":88, "nvalue":0, "svalue":""}

Obviously the nvalue state changes depending on the state of the switch (Sonoff or Domoticz)


EDIT: Never mind... Forgot to increase the MQTT_MAX_PACKET_SIZE to 400 as stated here: https://github.com/arendst/Sonoff-MQTT- ... erequisite

After doing that it works perfectly!

Hi, I have alternated the program to suit my need, but I have a question. How about if I use the dimmer or temp+hum sensor, what are commands then at >>msg2.payload.command = "switchlight";<< and >>msg2.payload.switchcmd=msg.stat;<<?
