Solution A - Z-Wave and LightwaveRF

Milestone 1 - Basic Functionality

Interact with simple switches and sensors.

Generic hub, Lightwave RF for non-essential control (lights), (duplex) Z-Wave for essential control (Heating)

Hub : Raspberry Pi Model B £40

Transceiver 1 : RFXtrx433 £77

Transceiver 2 : Aeon Labs Z-Stick £41

Control Software : Domoticz

Light Controls : Lightwave RF

Long Range : Lightwave RF signal booster

Milestone 2 - Heating

Control heating. Allow end-users to operate it.

TRVs : StellaZ

Control Software : OpenHAB

Boiler Control, 2 channel : Secure 2-channel Boiler Receiver

Thermostat : Horstmann Secure SCS-317, 7 Day programmable

Boiler Control, combi : Secure SCS317 + Secure ASR303

Milestone 3 - Reactive

Geofencing, presence and proximity trigger events.


Physical Layer

  • Powerline
  • RF

Link and Network Layer

Wired

  • X10
    • Too old?
  • UPB
  • Insteon
    • Successor to X10
    • Requires neutral wires in switch wiring box to work
  • IP over Powerline?

Wireless

  • Wifi
  • Zigbee
  • Z-Wave
    • 900MHz
    • Mesh
    • Two-way
    • Plug adapters ~£28
  • LightwaveRF
    • One-way fire-and-forget
    • Low cost
  • OpenEnergyMonitor (RFM12B)
  • WattWave

  • Lightwave vs Z-Wave

Hub Software

Control

  • Lighting
  • Lighting dimmers
  • Thermostat
  • Cameras
  • Motion sensors

Presence

  • Establish using Bluetooth link quality
  • Bluetooth adapters linked via MQTT to hub
  • Triangulate to establish location

Appliance Adapters

Z-Wave

Insteon

Networked dimmers

  • NXP chip with embedded IPv6 mesh networking over powerline

Thermostatic Valves

  • TRVs (Thermostatic Radiator Valves)
  • OpenTRV

Z-Wave

Thermostatic Systems

Boilers with out a bypass system:

  • All TRVs closed
  • Temperature is below set-point
  • Boiler is pumping against no circulation and cannot dissipate heat.
  • So there is usually at least one non-TRV radiator

Horstmann

Thermostat : Horstmann / Secure SCS317

Boiler Control : Horstmann ASR-ZW / Secure SSR303

Boiler Control, 2-channel : Horstmann ASR-RF / Secure SSR302

Nest

Honeywell EvoHome

  • Radiator valve sensor/controllers use RF 868MHz FSK
  • Possible interference with LTE
  • OpenTRV
  • Expensive
    • £208 starter kit (one controller)
    • £ 56 per TRV
    • plus installation
  • Blog by an EvoHome Installer

Dimmer Wall Switches

http://www.automatedhome.co.uk/vbulletin/showthread.php?3376-Uk-style-momentary-wall-switches!

Dimmer modules like Fibaro need push-button style switches also called:

  • Retractive
  • Momentary
  • Impulse
  • Push-button
  • Bell-push
  • Accessory dimmer
  • Slave dimmer
  • Roller-blind switch

Ideally we need "3-position retractive switches".
