10 Reasons for ripping out a £6k lighting system #Zwave #WiFi #IoT #InternetOfThings
Rob Dobson, a career wireless person, chronicles automating a new home in 2012:
…my wife and I started a house renovation project in Edinburgh (Scotland) having moved to that great city the previous year. In our previous London abode we’d installed a wireless lighting system from a company called Rako and it worked well enough to convince us that wireless was the way to go. Now, having installed and maintained a system with over 150 wireless lighting control circuits over the past 7 years I’ve finally had to admit that my technology choice was wrong. The Z-Wave wireless lighting system I installed just doesn’t work for a home like mine. I have now ripped out almost all of the Z-Wave units I installed – which had cost me more than £6k to buy and install.
For the home configuration, Z-Wave was just unworkable. Why? 10 reasons:
Z-Wave Pairing
Z-Wave Healing After Adding a Module
Scale
Resilience and Backup
Failure Concentration and Complexity
Failure Rate
Dead-Nodes
Handling Power-Failures
Poor Diagnostic Tools
The Cost
The new lighting system is WiFi based and costs a fraction of the Z-Wave system.
