To securize use MQTT password !

Cheers !

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

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

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. + - 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:
In from MQTT (only when executed by the sonoff):
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;<<?
