Open energy screen house Automation Hub with MQTT, nodeRED, OpenHAB & LightwaveRF

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):

Kontroll

Sentralvarme

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.

Interface

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 tovære en utmerket hus automatiseringsplattform. Stopp potensielt en rival til OpenHab.

Et annet valg for et grensesnitt er Nodered Dashboard som nå offisielt er en del av det noderne prosjektet.

Det fine med MQTT er at det er plattform agnostisk, det er mulig å ha mange forskjellige grensesnitt som kontrollerer nøyaktig samme administrasjonsnoder.

Stemmegrensesnitt

Jeg har nylig skaffet en taler for Google House-stemme, med litt assistanse fra Ha-Bridge for å etterligne en Philips Hue Bridge, det er ganske enkelt å få Google House til å administrere regionale dingser via MQTT. Den samme konfigurasjonen vil også fungere med Amazon Echo. Se HA-Bridge Configuration Guide for Emonpi.

Se videodemo øverst i dette innlegget.

Integrasjon og automatisering

Jeg bruker Nodered som er forhåndsbelastet på Emonpi / EMONSD for å integrere med andre tjenester som får den siste ytre temperaturen fra værforhold under jorden, send pushvarsler (oppvarming av / på temperaturvarsling) til telefonen min ved å bruke pushover. Begge disse tjenestene har ferdiglagde noderte strømmer, noe som gjør integrasjonen ekstremt enkel. Noderen er forhåndsinstallert så vel som konfigurert på Emonpi / Emonsd. Eksempelstrømmen som er inkludert på Emonpi, demonstrerer å lese Emonth -data fra MQTT samt data fra ytre temperaturer fra værforhold under jorden.

Jeg har også en noderen strømning som håndterer å slå av oppvarmingen når temperaturen i stuen (som bestemt av Emonth) når et settpunkt. Jeg har kanskje brukt termostatkontrolleren på WiFi -reléet for å gjøre dette, men det ville være vanskelig i mitt hjem å kjøre den kablede temperatursensoren fra WiFi -reléet til stuen, derfor bruker jeg en trådløs emontemperatur i stedet.

Sikkerhet så vel som ekstern tilgang

Fjernstyring (fra utenfor det regionale nettverket) kan oppnås ved å bruke en dynamisk DNS -tjeneste som DuckDNS eller Secure VPN for å gi tilgang til tjenester utenfra. F.eks. Åpne port 8080 for å gi tilgang til OpenHab som kjører på Emonpi fra Internett. OpenHab har godkjenning slått på, så vel som HTTPS kan brukes til å produsere en sikker tilkobling.

Alternativt kan det å være en mye bedre løsning være å bruke myopenhab.org -tjenesten for å muliggjøre ekstern administrasjon uten å måtte åpne en port eksternt.

Hjemmeassistent har fått et eksempel på å bruke Tor Onion Services for å få tilgang til husassistent som kjører lokalt.
