fixed : problems installing Fibaro Z-Wave Smart Thermostat and Room Sensor

Question :

I have chosen to install the Fibaro “The Heat Controller” in my home, and even though I have the Fibaro Z-Wave Home Center 3 Lite controller/hub already installed, I can’t get The Heat Controller (Z-Wave version) Smart Thermostat to connect to it. Whenever I try to connect from the Fibaro Yubii.app it can’t find the Smart Thermostat.

How do I set up the connection ?

Answer :

To install a Fibaro “The Heat Controller” (Z-Wave version) FGT-001 Smart Thermostat (that also comes in a Starter Pack combo teamed with the Fibaro FGBRS-001 Room Sensor), do this :

  • make sure you have the Yubii.app installed on your iPhone
  • make sure you have a ‘Z-Wave controller’ (a Z-Wave protocol hub/bridge device) set up, the most basic one that Fibaro offers is the Home Center 3 Lite
  • to prevent connection problems temporarily unmount/unscrew the Smart Thermostat from the radiator and make sure you have the Smart Thermostat near your Z-Wave bridge
  • >> if theSmart Thermostat is completely new, you will need to charge it first ; so plug in a micro-USB cable and power that using any USB (phone) charger, USB battery pack or USB wall outlet ; if the Smart Thermostat is fully charged it’s LED ring will flash in green
  • then, in the setting of your wireless router, make sure the WiFi is (temporarily) set to “2.4GHz only”
  • then, open the Yubii.app
  • in the Yubii.app on the main page, click the More button (bottom right)
  • in the MENU page that opens, click Add Devices
  • in the Z-Wave page that opens, wait until there is only one huge “Z-Wave protocol” button, then click on it
  • in the Add Device page that opens, click the blue Start button (bottom right)
  • on the next page, you will see a countdown circle of 60 seconds (so you now have 60 seconds to add the Smart Thermostat)
  • now, on the Smart Thermostat, long-press the small bubble button (so, press it for at least 1 second)
  • the LED ring on the Smart Thermostat should now light up (in blue)
    • >> if not, try again
  • if the LED ring is blue, triple press the small bubble button (so, press it for 3 times in a row)
  • the LED ring on the Smart Thermostat should now start blinking (in white)
  • >> if it does not, triple press the small bubble button again (and again, and again) with 1 second pauses until the LED ring starts blinking (in white)
  • >> if the circular countdown timer in the Yubii.app reaches 0 seconds before you get the LED ring blinking (on the Smart Thermostat) just try again
  • when the Smart Thermostat is recognised, just wait for the connection process to finish
  • when the connection has been established, the LED ring on the Smart Thermostat will change to let you know it was successful
  • >> if it was not, just try again
  • basically you’re ready now, so you can screw the Smart Thermostat back onto the radiator and start setting the scenes (operation programs) for the Smart Thermostat
  • do not forget to switch your WiFi setting back to “2.4 & 5GHz”
  • >> note #1 : in the Yubii.app you can only select scenes that you have already programmed ; all new scenes need to be programmed on the ‘Z-Wave controller’ first ( using the local web interface that you need to access from your browser ; if you have a Fibaro Home Center, access it by going to https://find.fibaro.com )
  • >> note # 2 : if screwing the Smart Thermostat back onto the radiator is difficult, turn the head knob of the Smart Thermostat until the LED ring flashes in red and you hear it buzzing (that will take the pressure of the valve inside the thermostat knob)

If you also want to connect the Fibaro “Temperature Sensor” FGBRS-001 Room Sensor (if you already have the Smart Thermostat installed) do this :

  • make sure you have the Yubii.app installed on your iPhone
  • make sure you have a ‘Z-Wave controller’ (a Z-Wave protocol hub/bridge device) set up, the most basic one that Fibaro offers is the Home Center 3 Lite
  • to prevent connection problems temporarily unmount/unscrew the Smart Thermostat (the one that you want to integrate the Room Sensor with) from the radiator and make sure you have the Smart Thermostat near your Z-Wave bridge
  • then, in the setting of your wireless router, make sure the WiFi is (temporarily) set to “2.4GHz only”
  • now, take out the plastic battery initiation strap from the Room Sensor (if it’s still there)
  • >> if there is no strap, the Room Sensor may have been used before and/or the the battery may be dead so the next installation steps will not work until you resolve this
  • >> if the battery is dead, use a coin to twist open the battery compartment and replace the battery first ( you will need a 3.0V CR2032 battery cell )
  • >> if the Room Sensor has been used before, it might still be connected/paired to other Smart Thermostats so you will need to reset it first, so use the F-marked pin to long press (press and hold) the button inside the hole for at least 2 seconds ; if the LED light on the Room Sensor blinks 3 times, the unpairing has succeeded (just try again if unsuccessful)
  • to continue the installation, open the Yubii.app
  • in the Yubii.app on the main page, click the More button (bottom right)
  • in the MENU page that opens, click Add Devices
  • in the Z-Wave page that opens, wait until there is only one huge Z-Wave button, then click on it
  • in the Add Device page that opens, click the blue Start button (bottom right)
  • on the next page, you will see a countdown circle of 60 seconds (so you now have 60 seconds to add the Room Sensor)
  • now, on the Smart Thermostat, press the small bubble button (so, press it once) for at least 1 second
  • the LED ring on the Smart Thermostat should now start blinking (in blue)
  • if not, just try pressing the small bubble button again
  • while the LED ring on the Smart Thermostat is blinking, use the F-marked pin that came with the Room Sensor to press the click button inside the small hole on the back of the Room Sensor
  • clicking the Room Sensor’s button is successful if a small light on the back of the Room Sensor lights up
  • if not, try pressing the click button inside the small hole again
  • Now, the LED ring on the Smart Thermostat should blink 5 times (in green) to indicate that the connection was successful 
  • if not, try pressing the click button inside the small hole again
  • if the countdown circle in the Yubii.app hits 0 seconds before you have the connection set up, just try again
  • That’s it
  • Do not forget to set your WiFi back to “2.4 & 5GHz”

enjoy !
