[Framework] Homie for ESP8266

Awesome!

For the reset yes, this is a known Arduino for ESP8266 issue (esp8266/Arduino#1017).

@Lee_Berry exactly what was my issue with my Arduino under my stairs for light and motions sensors.

I do not use ESP but an Ethernet shield…
My lights work with or without Ethernet (stan alone…) but if there’s and Ethernet and and MQTT connection available I can subscribe and publish command/status/info to my broker…

This ty of sketch example is really hard to find on google! Espescially without Ethernet.connect function because it hang for 60 second and I want not the light not be responding every time Arduino t’check for Ethernet connection…

@qtronik

" but if there’s and Ethernet and and MQTT connection available I can subscribe and publish command/status/info to my broker…"

are you after a broker ? im using HiveMQ.com and paho to test the MQTT broker and configuration … all very easy to setup.

Guys, I am about to release the v1.4.0. It has, along with a few fixes:

The new $uptime device property
The ability to subscribe a node to every properties. This is useful for a led strip for example: you will not want to do node.subscribe("1"); node.subscribe("2"); ... if you have a thousand LED. So now, with a fourth parameter to the HomieNode constructor, you can subscribe to everything. See the LedStrip example for a concrete use case

But before, can you please test if your current sketches work / if the new features work without any regression. If you can, thanks.

Another question, some of you noticed some frequent MQTT disconnections. I personally don’t, but I heard this is a common problem with knolleary/PubSubClient. I am considering, for the v2.0.0, to switch to imroy/pubsubclient, which seems more stable. Do you have any feedback on this library?

My mqtt (Mosquitto) is on my local RaspberryPi with openhab. And a port is open on my LAN and redirected to my services on RaspberryPi so my outside app (android openHab and OwnTracks) have access.

Easy but long learning curve…
For what ever reason my LAN reset or crash I wanted my devices to be standalone. I want my light to be turned on (sensors,switches) without MQTT too!
I don’t want my stuff to be dependent to cloud… If I change something I know it

Has anyone got openhab to work ?

i can use another mqtt client to talk via the MQTT broker and then the device , no problem , light on and off and receiving other properties like $uptime

but trying to get openhab working seem to be painful.
I have cut it down the to basics …

Sorry for BOLD TEXT below , must be a mark up in the code!!

items file >
Switch light {mqtt="<[broker:devices/1198d5e0/light/on:state:ON:true],<[broker:devices/1198d5e0/light/on:state:OFF:false],>[broker:devices/1198d5e0/light/on/set:command:ON:true],>[broker:devices/1198d5e0/light/on/set:command:OFF:false]"}

sitemap>

sitemap home label="Main Menu"
{
   Frame label="MQTT" {
 
   Switch item=light label="Office Lamp"
  }  
}	

Config

overall very simple , but i can not get openhab to talk to the MQTT server

Thanks

found the problem… missed of /set in the items , working now … 2 days later omg

but interesting the light icons on change with a browser’s refresh F5

Hi everyone… I’ve just received my Wemos D1 mini boards with relay shield and I was wondering if anyone has done any work getting a nice garage sensor setup?

What I’m trying to achieve is being able to activate the relay via MQTT so that it closes for 1 second and then opens again. In addition there also needs to be an open/close sensor to let me know if the garage door is open or closed at the moment.

I can fumble my way through it but hey, if anyone has already put one together then I’d love to borrow some code that works with homie

@marvinroger: with the release 2.2.0 of arduino for esp8266 released, is there and good thing that is planed to go into your framework ?

Asking in a general idea

marvinroger · April 19, 2016, 1:22pm

Yes! There will be support for mDNS querying. In other words, instead of providing the host and port of both your OTA and MQTT servers, you can now provide the mDNS service name if the servers support mDNS, so that it will be discovered automatically.

Rigor_M · April 19, 2016, 1:50pm

This is pretty cool.

For those that uses openHAB, I think (not sure on this part tough) openhab2 has a discovery of some sort… maybe it uses mdns also.

Would be cool to have a openhab binding that would support your framework… would make life so easy on the integration of the modules in openhab

marvinroger · April 19, 2016, 2:03pm

You misunderstood, I said mDNS querying, not advertising. There is no need for the ESP8266 to advertise itself on mDNS as this is already done on the MQTT broker. So it would be possible to make an openHAB binding that would scan the MQTT broker in order to discover devices.

Rigor_M · April 19, 2016, 2:16pm

oh right… querying… as in find the mqtt server with a dns name… sorry my bad… but still, you be fun to have a binding to find the module and add them to openhab in a easy fashion !

“/homie/config.json doesn’t exist” !!!

i have configured via the JSON web app etc , works fine.
MQTT broker working fine
Light on and off …

Great

Go to bed , come back the next night
and
"/homie/config.json doesn’t exist" !!!

i have not worked the time frame , but if there is no power for more than 30 mins , the Config is removed
5 mins seems ok

Any ideas ?

Thanks

ben_jones12 · April 20, 2016, 9:36am

Possibly something related to this?

Lee_Berry · April 20, 2016, 9:58am

thanks i’ll give a try

Lee_Berry · April 20, 2016, 9:59am

installed new homie library and i get the following compile error

error: ‘class MDNSResponder’ has no member named ‘queryService’

i can not fined the definition of MDNSResponder , any ideas ?

Thanks

marvinroger · April 20, 2016, 11:54am

Please download releases, not the git development version.

Hi Homie sounds greeat, just what i was looking for, but a can’t get it to configure. checked all dependances in arduino and it compiles and uploads to board.i am using arduino ver 1.6.8. and have tried it on a WeMos D1 R2 and a ESP12E DEV KIT. and get the same error on both.i open…http://marvinroger.github.io/homie-esp8266, and get the “waiting for device” i then switch to homie AP and after a few seconds it gets the device info. i then follow the instructions filling in required fields. (do i need http://192.168.0.22 or just 192.168.0.22 in MQTT broker settings)after completing this it says “Sending Configuration” then “There was an error while sending the configuration. Please retry.” ihave been trying for 2 evenings now. Hope you can help Many thanks Chris.
P.S. Sorry if i have posted this in wrong place.
