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):
Kontrol
Merkezi ısıtma
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.
Arayüz
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 toMükemmel bir ev otomasyon platformu olun. Potansiyel olarak Openhab’a rakibi durdurun.
Bir arayüz için başka bir seçenek, artık Soylu Projenin resmi olarak bir parçası olan Nodered Gösterge Tablosudur.
MQTT’nin güzelliği, platform agnostik olmasıdır, aynı yönetici düğümleri kontrol eden birçok farklı arayüze sahip olmak mümkündür.
Ses arayüzü
Kısa bir süre önce bir Google House Voice tetiklenen hoparlör aldım, bir Philips Hue Köprüsü’nü taklit etmek için HA-Bridge’den biraz yardımcı olarak Google House’un MQTT üzerinden bölgesel gadget’ları yönetmesi oldukça basit. Aynı yapılandırma aynı şekilde Amazon Echo ile çalışacaktır. Emonpi için HA-Bridge Yapılandırma Kılavuzuna bakın.
Bu yazının başında video demosuna bakın.
HA-Bridge Web Page GUI kullanan cihaz yapılandırması:
Google House Uygulama Kurulumu:
Entegrasyon ve Otomasyon
Emonpi / Emonsd üzerinde önceden yüklenmiş olan Nodered’i kullanıyorum, hava durumu yeraltından en son dış sıcaklığı almak, itme bildirimlerini (ısıtma / kapama sıcaklığı uyarısı) itme pushover kullanan telefonuma gönderin. Her iki hizmet de entegrasyonu son derece kolay hale getiren önceden hazırlanmış nodered akışlara sahiptir. Nodered, Emonpi / Emonsd üzerinde yapılandırılmış olarak önceden yüklenir. Emonpi’de yer alan örnek akış, MQTT’den Emonth verilerinin yanı sıra yeraltındaki hava durumundan dış sıcaklık verilerini okuduğunu gösterir.
Aynı şekilde, oturma odasındaki sıcaklık (Emonth tarafından belirlendiği gibi) bir ayar noktasına ulaştığında ısıtmayı kapatan bir nöbet akışım var. Bunu yapmak için wifi rölesinde termostat kontrolörünü kullanmış olabilirim, yine de evimde kablolu sıcaklık sensörünü WiFi rölesinden oturma odasına çalıştırmak zor olurdu, bu nedenle kablosuz bir emonth sıcaklığı kullanıyorum.
Güvenlik ve uzaktan erişim
Dışarıdan hizmetlere erişim sağlamak için DuckDNS veya Secure VPN gibi dinamik bir DNS hizmeti kullanılarak uzaktan yönetilen (bölgesel ağ dışından) gerçekleştirilebilir. Örneğin, Emonpi’mde internetten çalışan OpenHab’a erişim sağlamak için 8080 bağlantı noktasını açıyorum. OpenHAB, kimlik doğrulama açıldı ve HTTPS güvenli bir bağlantı üretmek için kullanılabilir.
Alternatif olarak, potansiyel olarak çok daha iyi bir çözüm, harici olarak bir bağlantı noktası açmak zorunda kalmadan uzaktan yönetimi sağlamak için myopenhab.org hizmetini kullanmak olabilir.
Ev asistanı, yerel olarak çalışan ev asistanına erişmek için Tor Onion hizmetlerini kullanma örneğine sahiptir.
