Bathroom Downstairs

On this page, I present the actual solutions installed in the downstairs bathroom of our smart home, with links to specific products used and how these have been set up

This room contains solutions for the following systems (notice that on phones, the table might only be displayed in landscape mode):

System Type Components
Lighting
  • Fibaro Walli Switch

  • Philips Hue motion sensor

  • LED lights for closet door hinges

Climate Control
  • Heatmiser neoStat-e thermostat

Home Entertainment None
Security and Alarm
  • Aqara water leak sensor

  • Verisure water leak sensor

Pet Care None
Control and Automation None

Description of the solutions in this room

This is a bathroom primarily used by guests and has the following solutions and has some less complex solutions for control of lighting, climate control of underfloor heating, and monitoring for leakages. The lighting in this bathroom consists of a number of downlights installed in the ceiling and integrated LED lights in a shelf above the mirror, see pictures below.

Some of the downlights in this bathroom; a solution could of course have been to replace these with downlights from Philips Hue, but this would both be much more expensive and much more work than the Fibaro relay

The lights above the mirror (in this picture, you can see the motion sensor, but it was later moved since it responded to slowly when placed here)

There is strictly speaking nothing “smart” about this, but a rather elegant lighting solution is a simple LED light that is installed on the hinges of closet doors, see pictures below. The lights turn on/off when you open/close the doors.

These were all originally controlled by a manual on/off wall switch placed next to the bathroom door in the adjoining hallway, as well as a wall dimmer switch that only controls the downlights. In the same way as for the bathroom upstairs, it would have been nice to achieve a way to turn on full lights during daytime and reduced night light at night. However, since the dimmer switch only controls the downlights and there is no separate switch for the LED lights, I have not found any way to do this which does not involve a massive replacement of light sources or rewiring of the switches. Thus, the solution ended up as follows (see pictures below) installation of a Fibaro Single Switch in the wall box behind the on/off wall switch and controlling the lights using a Philips Hue motion sensor turned toward the door.

On the left, it does not show here which of course is a point in itself, but behind the wall switch, there is a Fibaro relay

On the right, the Philips Hue motion sensor is placed on top of the “box” that contains the cistern

The only downside of this solution is that the light module above the mirror contains both LED spots pointing downward and an old-fashioned fluorescent tube pointing upward. It is possible it might have worked, but since the Fibaro relay is not meant to be used with fluorescents, I upgraded the solution here when Fibaro in January 2019 announced a new switch, Walli Switch, which also works with fluorescents. Since this is a single pole switch, I had to keep the old double pole wall switch and install the Fibaro switch above the old switch stack, see picture below. Perhaps not the most elegant solution, but it works.

Contrary to the smart relay from Fibaro, the Walli line is not compatible with HomeKit. Therefore, the switch had to first be connected to Homey and via Homeykit to HomeKit. The programming is very simple; all lights turn on when motion is detected (and automatically off after 15 minutes without any movement), no matter what time of day or night, see screenshot below.

With regard to climate control, this bathroom has the sam Heatmiser neoStat-e thermostat as we have installed elsewhere in the house. Also here, the thermostat is located outside the door to the bathroom, see picture above, but with a floor sensor underneath the tiles in the bathroom, this works perfectly.

Finally, in the category of security & alarm, we have two leakage sensors in this room, one from Aqara and one from Verisure (also here two sensors because only some of the functionality of the Verisure sensor ports over to HomeKit). This bathroom has a wall-mounted toilet with the water cistern built into a “box”, with access to the box through an inspection hatch. Hopefully, there is little likelihood of a leak inside this box, but instead of having to conduct regular inspections (or risk an undetected leak), it is useful to monitor this through a sensor. There are many leakage sensors available, e.g., from Fibaro (which is also HomeKit-compatible), we went with an Aqara sensor, which works very well, but it doesn’t provide temperature measurements.
