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):
Ao controle
Aquecimento central
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 toSeja uma excelente plataforma de automação de casas. Pare potencialmente um rival para o OpenHab.
Outra opção para uma interface é o painel assentado, que agora faz parte oficialmente do projeto assentado.
A beleza do MQTT é que é agnóstico da plataforma, é possível ter muitas interfaces diferentes que controlam exatamente os mesmos nós de gerenciamento.
Interface de voz
Recentemente, obtive um alto-falante acionado por voz do Google House, com um pouco de assistência da Ha-Bridge para imitar uma Philips Hue Bridge. É simples fazer com que o Google House gerencie gadgets regionais via MQTT. A mesma configuração exatamente funcionará com o Amazon Echo. Veja o Guia de Configuração do HA-Bridge para Emonpi.
Veja a demonstração de vídeo no topo deste post.
Config de dispositivos utilizando GUI da página da Bridge HA-Bridge:
Configuração do aplicativo do Google House:
Integração e automação
Utilizo o nodado que é pré-carregado no emonpi / emonsD para integrar-se a outros serviços, obtendo a temperatura externa mais recente a partir da condição climática no subsolo, envie notificações push (aquecimento de alerta de temperatura ligado / desligado) para o meu telefone utilizando pushver. Ambos os serviços têm fluxos as conchados pré-fabricados, tornando a integração extremamente fácil. As nodorias são pré-instaladas e configuradas em emonpi / emonsd. O fluxo de exemplo incluído no emonpi demonstra a leitura de dados do emonte do MQTT, bem como dados externos de temperatura da condição climática no subsolo.
Da mesma forma, tenho um fluxo assentado que lida com o desligamento do aquecimento quando a temperatura na sala de estar (conforme determinada por Emonth) atinge um ponto de ajuste. Eu poderia ter utilizado o controlador do termostato no relé Wi -Fi para fazer isso, no entanto, seria difícil em minha casa executar o sensor de temperatura com fio do revezamento WiFi para a sala de estar; portanto, utilizo uma temperatura sem fio.
Segurança e acesso remoto
O Remote Manage (de fora da rede regional) pode ser realizado utilizando um serviço DNS dinâmico, como DuckDNS ou Secure VPN, para fornecer acesso a serviços de fora. Por exemplo, abro a porta 8080 para fornecer acesso ao OpenHab em execução no meu emonpi na Internet. O OpenHab tem autenticação ativada e HTTPS pode ser utilizada para produzir uma conexão segura.
Como alternativa, além de uma solução muito melhor, pode ser utilizar o serviço myopenhab.org para permitir o gerenciamento remoto sem precisar abrir uma porta externamente.
O Home Assistant recebeu um exemplo de utilização de serviços de cebola para acessar o Assistente da Casa em execução localmente.
