Homie as a convention for MQTT based IoT solutions

This entry is part 1 of 2 in the series esp8266

Reading time: < 1 minute In this video I describe deeply a convention called "Homie“; thanks to that we have a set of rules and assumptions very useful when a firmware device is created and/or an IoT platform have to be configured to support those devices. I love that convention and I used it during my demonstration scenario in Lviv IT Arena.

After this video I’ll follow a series of some other videos, describing how to develop devices following Homie conventions.

Official documentation of the convention can be found in the Github Homie project.

Conference: Smart Home using low cost components at IT Arena, Lviv (UA)

Reading time: 2 – 2 minutes

Last weekend I talked on IT Arena event organized in Lviv (Ukraine) at Lviv Arena Stadium created for the Football Eurocup of 2012. It was a very good and well organized event, it was a privilege to participate. I gave a presentation about the automation’s that I created latest years at home thanks to the open software and open hardware. The second part of the presentation was a demonstration about how to set up some IoT devices created ad-hoc.

If you want to review the slides, they are available at slideshare.

Conference was recorded but for a while I don’t have the video clip, if I can get access to the video I’ll upload it to youtube and referenced here. Anyway I created a photo album that you can review in LVIV trip pictures photo album.

Finally I want to give thanks to Mykhaylo Kramarenko because thanks to his invitation I had that great opportunity. Thanks to Marta Maksym to take care of my trip and accommodation. Thanks to organizers for the 3G SIM card with data and free calls, next time a micro-SIM card will be perfect for my mobile phone XD and last but not least a lot of thanks to Denis Kolesnikov for his guided visit to the Lviv center, really nice place I’ll go back to visit it properly.

Conferència Summer Camp Garrotxa 2015: SmartHome usant Arduino, Raspberry PI i més

Reading time: 1 – 2 minutes

Aquest cap de setmana vaig tornar a donar la meva conferència sobre “SmartHome” en aquesta ocasió vaig introduïr la novetat del sistema de feedback basat en “Tasker + Auto-notification”, a més de l’execusió de tasques basades en “crontab”. També he inclòs un petit avanç sobre el nou projecte en el que estic treballant per tal d’integrar les dades del descalcificador dins del OpenHAB usant una webcam i OpenCV per processar les imatges optingudes.

Agraïr al Xavi, Gerardo i la Laura per haver-me donat aquesta oportunitat. Tant el SCG15 com el SAX2015 són events molt familiars a més l’entorn és espectacular. Tot un descobriment del que malgrat tenir referències no havia pogut disfrutar en primera persona.

Conference: SmartHome using Arduino, Raspberry PI and more

Reading time: 1 – 2 minutes

I did this conference twice but this time it’s in English as I said before in Catalan, this is how I’m getting real a childhood dream. Thanks to open hardware like Arduino and Raspberry PI and open source software like OpenHab I have a smarthome with several automations. Last Thursday I spoke in “IoT Barcelona meetup” sharing my personal experience automating my house.

Conferència: SmartHome usant Arduino, Raspberry PI i més

Reading time: 1 – 2 minutes

El dia 12 de febrer al vespre vaig fer una conferència a la FIB (Facultat d’Informàtica de Barcelona) dins de la UPC (Universitat Politècnica de Catalunya). En aquesta xerra vaig estar explicant com vaig convertint en realitat un somni que vaig tenir quan era petit, estic parlant de domotitzar la casa. Gràcies a enginys com l’Arduino i la Raspberry PI a més d’aplicacions com l’OpenHab podem fer assequible allò que si anem a grans marques comercials es fa caríssim pel meu pressupost.

En aquest enllaç podeu trobar les transparències de:  SmartHome usant Arduino Raspberry i més i el video el teniu disponible al servidor de la FIB.

Ara també teniu disponible el video a youtube:
