At the completely Charged online event at Silverstone earlier this month we stopped by the open energy screen mean a chat with Glyn Hudson (check out the NIEVO video below for a taste of the show).
Glyn’s wise house configuration is based around the emonPi as well as employs MQTT, nodeRED, OpenHAB, LightwaveRF as well as Google Home.
Over to Glyn for all the great stuff…
I believe automation can play an useful function in assisting to reduce energy consumption. For example being able to manage my house central heating system remotely allows me to only turn on the heating when it’s needed as well as not have it running on a set routine when the home is empty.
As previously mentioned in a blog post, the emonPi (running emonSD pre-built SD card) can function as a powerful house automation hub. Utilising the emonPi as a house automation hub is a great in shape for a number of reasons:
It’s already running 24/7 for energy monitoring
It’s optimised for robust long term operation: the root Raspberry Pi file-system is read-only to boost SD card lifespan
It’s already linked to your regional network
It’s running Debian Raspbian Jessie therefore installing additional bundles is simple as well as great deals of support is available
Raspberry Pi 3 has lots of area capacity
Extra radios / accessories can be linked via USB
It’s already running an MQTT server
emonSD pre-built SD card comes pre packed with the complying with integrations nodeRED, OpenHAB as well as LightWaveRF
In this publish I want to show you exactly how I utilize the emonPi in my own home.
Here is a video demo utilizing Google house to manage my central heating as well as gadgets via MQTT:
Read on to discover exactly how this is accomplished utilizing an emonPi as well as open-source software…
There are many many choices when it comes to house automation as well as control. Where possible I prefer open-source solutions which do not depend upon any type of third-party services. All the software application services for my house system as I explain in this publish runs locally on my emonPi as well as apart from Google house voice integration does not need an Web connection to function. A self-hosted open-source solution has the added benefit of increased privacy as well as security which you are in completely in manage of.
MQTT
MQTT lightweight communication protocol is utilized as the ‘glue’ communication layer between all the complying with services. See technical/MQTT section of the individual guide for more information about exactly how MQTT works on the emonPi.
Energy Monitoring
Emoncms…obviously!
Recently I have been loving utilizing the V2 Emoncms Android app (currently in beta) which supports several pages (see forum thread).
Video demo Emoncms Android app V2 beta:
I have likewise just recently enjoyed utilizing the redesigned Emoncms apps module which have just bee released on Emoncms.org. It’s now possible to have more than one MyElectric or MySolarPV ‘app’ per Emoncms account as well as economic climate 7 split time of utilize tariffs are now supported (see forum thread):

Centrale verwarming
To manage my gas central heating boiler I utilize an MQTT WiFi relay which likewise has a developed in thermostat as well as scheduler, although I don’t utilize these features, I just manage directly via MQTT. The WiFi Relay has been extremely reliable, it’s been utilized everyday for the past two years in my house as well as never when needed a reboot.
Plug sockets (lights)
I utilize LightWave RF plugs to which I have lights as well as other entertainment gadgets linked e.g. stereo as well as chromecast. being able to switch a whole plug bank on/off has the advantage of being able to turn gadgets completely off when not in utilize to minimise any type of vampire drain.
The emonPi can manage LightWave RF gadgets directly via MQTT if an RF OOk modules is fitted. See LightWave RF emonPi individual Guide.
LightWave RF gadgets are not perfect, the OOK RF protocol is simplistic, unsecure, sometimes unreliable as well as specify comments is not available. I am thinking about swithcing to ESp8266 based Sonoff plug with third celebration MQTT firmware or EmonESP firmware.
Koppel
For the past few years I have been utilizing OpenHAB as the manage interface. OpenHAB is pre-loaded onto the emonPi emonSD pre-built image. I am yet to upgrade to OpenHAB V2.0, it looks extremely nice. However, V1.8 has been extremely dependable as well as fits my needs. I utilize the OpenHAB Android app to access the interface quickly from my phone:
OpenHAB likewise integrates with my Pebble smartwatch which makes it super simple to turn on/off the heating while out as well as about:
A while back (early 2016) I dabbled with HomeAssistant, (see blog post). I was rather impressed, I have been complying with the job as well as it appears like it’s matured toWees een uitstekend huisautomatiseringsplatform. Stop potentieel een rivaal van OpenHab.
Een andere keuze voor een interface is Nodeed Dashboard dat nu officieel deel uitmaakt van het Nodeerde Project.
Het mooie van MQTT is dat het platform agnostisch is, het is mogelijk om veel verschillende interfaces te hebben die exact dezelfde beheren knooppunten regelen.
Spraakinterface
Ik heb onlangs een Google House-stem geactiveerd spreker verkregen, met een beetje assist van Ha-Bridge om een Philips Hue Bridge na te bootsen, het is vrij eenvoudig om Google House te krijgen om regionale gadgets te beheren via MQTT. De exact dezelfde configuratie werkt ook met Amazon Echo. Zie HA-Bridge Configuration Guide voor Emonpi.
Zie video -demo bovenaan dit bericht.

Google House App Setup:
Integratie en automatisering
Ik gebruik Nodeed die vooraf is geladen op Emonpi / EmONSD om te integreren met andere services, zoals de nieuwste buitentemperatuur krijgen van de weersomstandigheden ondergronds, stuur duwmeldingen (aan / uit-temperatuurwaarschuwing aan / uit) naar mijn telefoon met behulp van Pushover. Beide services hebben vooraf gemaakte knikstrookjes die integratie uiterst eenvoudig maken. Nodeed is vooraf geïnstalleerd en geconfigureerd op Emonpi / EmONSD. De voorbeeldstroom op Emonpi toont het lezen van Emonth -gegevens van MQTT en buitentemperatuurgegevens uit ondergrondse weersomstandigheden.
Ik heb eveneens een knoopstroom die de verwarming afhandelt wanneer de temperatuur in de woonkamer (zoals bepaald door Emonth) een ingestelde punt bereikt. Ik heb misschien de thermostaatcontroller op het wifi -relais gebruikt om dit te doen, toch zou het in mijn huis moeilijk zijn om de bekabelde temperatuursensor van het wifi -relais naar de woonkamer te laten lopen, daarom gebruik ik in plaats daarvan een draadloze temperatuur van het emonteren.
Beveiliging en externe toegang
Remote beheren (van buiten het regionale netwerk) kan worden bereikt met behulp van een dynamische DNS -service zoals DuckDNS of Secure VPN om toegang te bieden tot services van buitenaf. Bijvoorbeeld ik open Port 8080 om toegang te bieden tot OpenHab die op mijn emonpi van internet loopt. OpenHab heeft authenticatie ingeschakeld en HTTPS kunnen worden gebruikt om een veilige verbinding te produceren.
Als alternatief, evenals mogelijk een veel betere oplossing, is het mogelijk om myopenhab.org -service te gebruiken om externe beheren mogelijk te maken zonder een poort extern te openen.
Home Assistant heeft een voorbeeld van het gebruik van TOR -uiendiensten om toegang te krijgen tot huisassistent die lokaal loopt.
