Equipment Z-wave

In our reviews, we often mention equipment based on the Z-wave protocol. According to Ebiding specialists, this is one of the best entry-level systems that can serve as a starting point into the world of home automation for both hobbyists and commercial use.

Z-Wave — is a wireless home automation standard for apartments, houses and small offices.

Z-Wave does not require additional wiring and other repairs
Easy to install allows you to customize the entire system
Flexibility and the ability to consistently increase the functionality by installing additional devices will make it possible in the future to adapt the system to the changing needs of the owners.

Dignity:

Controllers have different costs. Starting from 5000eu (Homemade controller based on Raspbery PI with Zwave chip.
Large device peripherals. Various thermostats, humidity sensors
Wireless interface. (the controller itself, however, must be connected to the central router. By wire.)
The cost of a solution for a specific case (controller + leak + smoke + security camera can cost much less depending on the required functionality.

Flaws:

The price is pegged to the euro exchange rate.
Some interoperability issues with devices from different manufacturers. It is necessary to study the specific specification before ordering the equipment.
General system immunity
General network vulnerability. ( Valid for any network that has the ability to remote control.
Very limited number of supported IP cameras.

Work scenarios:

1. Control curtains and blinds

Integrated control relay for curtains, blinds, etc. Designed for installation in an in-wall wiring box under a traditional switch. (requires space) or in concealed mounting locations. The relay controls the load on the blinds motor. Can be included in a common Z-Wave network and controlled from other devices. Allows you to control any motorized lifting / lowering devices. (doors? garage, attic sliding curtains, etc.) The average cost of one drive is 400eu.

The system works great with controllers of all types (Fibaro connects automatically, others may need tweaking)

Works with automation from (BOFU, Somfy, Trietex, G-Rail, raex

2. Remote control of electrical appliances (smart sockets)

Represented by overlays for existing sockets (could not be found mounted in sockets.

Allows you to remotely enable / disable a consumer group, combine them into groups. Turn off by a signal from other sensors, time of day, timer, etc.)

Price from 300eu. For 1 device.

3. Security system

Fibaro leakage sensor	480
Everspring Smoke Detector	400
Eversrping Presence Sensor	250
Everspirng Door/Window Sensor	280
Ip camera Foscm	310
Total	1720

Calculation example for one room. If there is no need for any sensors, the system can be configured without them.

It must be remembered that devices run on batteries (batteries that need to be replaced periodically, although the devices themselves are low power consumption,

4. Lighting control

Zwave controls lighting. With the help of relay modules mounted behind the sockets. The system supports dimmable lighting and RGWB control (color LEDs). Scenarios can be set. The control module has four analog inputs, allowing you to connect any sensors operating in the 0-10V range, including light sensors, wind sensors, pressure and humidity sensors.

The cost of one module is about 400eu.

5. Home air conditioner control.

The Remote ZXT-120 is a Z-Wave to IR radio converter for air conditioners and is 100% compatible with Z-Wave devices (such as home gateways, portable controllers). Remotec ZXT-120 has a built-in temperature sensor, the value of which can be transferred to the Z-Wave network. The choice of the IR code for controlling the air conditioner is carried out by a configuration parameter from the library built into the expander. The cost of this sensor is about 400 eu.

The device comes preloaded with IR codes from the following manufacturers: ACURA, Apton, AUX, Carrier, Chang Hong, Chigo, Chunlan, Daikin, Fujitsu, Galanz, General, Gree, HAIER, Hisene, HITACHI, Kang Li, Kelong, Kelvinator, Kolin, Konka, LG, Midea, Midea_Toshiba, MITSUBISHI, NEC, Panasonic, Panda, Philco, Samsung, Sanyo, SHARP, Shinco, Siemens, TCL, Toshiba, Trane, VOLTAS, YORK.

6. Heating control (thermostats)

The water valve thermostat allows you to adjust the temperature in a room heated by water radiators.

Four modes are supported:

Normal mode
Energy saving mode
Frost protection (off)
Direct valve position control mode. The thermostat has no buttons except for one service button, mode switching and temperature change are carried out via Z-Wave using the controller.

The device has an algorithm for temporarily turning off heating when a window is opened. After 5 minutes, the thermostat returns to the usual temperature control pattern. The cost of the solution is from 500 eu for one battery.

How easy it is to calculate the equipment, for example, a 3-room apartment can do.

Device	Quantity	Cost EU
Controller	1	1700
Light relay	3	(400*3)=1200
RGWB relay	1	400
Leak sensor	1	480
Smoke detector	1	400
Presence sensor	1	250
Everspirng Door/Window Sensor	4	280*4=1120
Ip camera Foscm	2	310*1=620
A/C controller	2	400*2=800
Thermostat	4	500*4=2000
Blind controller	4	600*4=2400
	Total:	12570

As you can see, the solution is quite inexpensive for complex management. The cost of installation work (if you do not need to pull the wiring, for example, to control the blinds, you can estimate at 10-15t eu . + 5t eu . setting up the router and controller.

Total 12570 eu.
