MQTT doorbell

deedjedeedje Member
in Devices
Hi

I have orderd a Homey, but as other people im still waiting on it.

However, i do have a doorbell that i have connected a ESP8266 chip to, this chip send a MQTT message to a MQTT server (Whould be the Homey device), Can i make a flow with MQTT on Homey that "if" myhome/doorbells/frontdoor7/ring is recived, it should take a snapshop from a camera and send that to the iOS app?

I would also like it to play a doorbell song on my Xiaomi hub?

    A little bit off topic. I also do have ESP8266 devices. I use these with a Rapberry Pi to send temp data but not using MQTT. But using my own TCP protocol. I like to have more knowledge about MQTT. (I don't know how to use it). Do you have a link or so showing me how you use MQTT in combination with ESP8266. If it not fitting in this topic, please feel free to do it with PB

    I know Homey is having MQTTBroker and Client, so it must be possible to use MQTT with Homey.

    With the MQTT client app you can create a trigger on a specific topic. That means if a message on that topic is received, that triggers activates a flow where you can specify actions that homey can do.

    Very good!

    Then i should be able to get pretty much all my MQTT stuff to works, for execpten for maybe the temp sensors?
    I have some in places where I rather not wanna change batteries.

    I also have an Android alarm panel, that i wanna build into my wall. I wanna use this one to alarm and disarm the alarm system. Should also not be any problem then?

    Well the MQTT client trigger has a tag that contains the message content posted on the  triggered topic. So if the temperature is posted, the trigger has a token that will contain the temperature (well the whole payload).

    I can see the MSG from temp sensor and doorbell on my MQTT server (In homey) but when i try to make a flow for it and write "on" in msg, save and then it forgets it.

    20180217-14:51:08 Packet published on

    Is what i get when I push the doorbell. Can anyone show me an exemple on a flow?

    Get the card from MQTT which says receive topic triggers. That’s the card with the tags
  • deedjedeedje Member
    Yes, thats what im trying todo, but i only get "undefined" when i push the save button

  • RocodamelsheRocodamelshe Member


    Looks like u need to put "Packet published on" in the left card?
  • deedjedeedje Member
    I did try this, i see in the logs when i press the button
    "20180217-21:14:34 Packet published on"

    Is there anything im missing?

    So, did u try to fill : "Packet published" in the card?
  • deedjedeedje Member
    Did try that now, still dont work :(
  • RocodamelsheRocodamelshe Member
    Well, u have to fill in the message the chip is sending. It's also case sensative so it has to be the precise message u fill in there.
  • deedjedeedje Member
    Yep. What about the topic? Do i need to fill that in?
  • RocodamelsheRocodamelshe Member
    Yes, enter the topic. Just the topic and case sensative!
