Installation and Operating Instructions
Version for Smartphones and tablets with iOS operating system
1. Description of the Wi-Fi relay
A member of the Smart4house product family, the Wi-Fi relay is designed for remote control of
one or more devices with inputs for potential-free contacts, viz. via the Smart4house application
in your Smartphone or tablet. Requests for output relay connection/disconnection are
transmitted from the Smartphone/tablet to the cloud, from where they are transmitted to the Wi-
Fi relay through your AP –Access Point and the Wi-Fi 802.11b/g/n network. The same path is
then used by the Wi-Fi relay to send information about implementation of the request. The Wi-Fi
relay is equipped with a pair of output relays with switching contacts. The output relay status is
indicated by LED controls. The output relay either may be operated in the on/off mode or a 1-
second switch-on pulse may be generated. The information transmitted is secured by
encryption.
Two Wi-Fi relay versions differing in their power supply are marketed:
a) Model S4H-RE-00: powered with 5 VDC from a Micro B USB
a) Model S4H-RE--10: powered from a 12-24 V AC/DC supply
Note: The source for powering from USB is not included in the delivery.
2. Installation manual
Fasten Wi-Fi relay 1 to a dry, smooth and firm surface with 2 screws and wall plugs (included in
the delivery) or with a double-sided adhesive tape. To access the holes for the screws, remove
cover 2 by sliding it in the direction of the arrow. Connect the device to be controlled to the Wi-Fi
relay via screw terminals in terminal box 3.
Wi-Fi relay electronics include components which are susceptible to
electrostatic charge. Do not touch any component except the terminal box
screws and the initialising button when installing the product.

The Wi-Fi relay must be located within the reach of the AP/router (Access Point) signal with
which the relay will communicate and to which it will be configured. Test the AP signal quality in
the future Wi-Fi relay location on the Wi-Fi communication screen of your smartphone/tablet.
The Wi-Fi relay should be located at a well accessible site for easy initialisation, in areas with no
water vapour condensation, temperature 0°C to 50°C (32°F to 122°F). The Wi-Fi relay includes
a Wi-Fi signal transmitter/receiver and so it should not be installed at a distance of less than 20
cm from long-term presence of a human body.

In the Pulse mode the relay generates a 1-second pulse on
pressing the activation button on screen 3.3.b.
The active mode is indicated by blue background.
Note: The relay must be off to be switched to the pulse mode.
This screen also serves to set the Wi-Fi relay behaviour if its
communication with the cloud has been lost/resumed, or when
WiFi relay power down.
If the keep status switch is OFF ( default setting ) and connection is lost, or power goes down,
the relays will open ( safety state ). The relays will stay open after re-establishing the
communication or when power up.
If the keep status switch is ON, the WiFi relays will keep their output relays in the most recently
selected state during the communication failure period. The relays will get to the selected state
after power up.
If the Wi-Fi relay power supply fails, the two relays will be brought to the initial safe state
irrespective of the keep status switch setting. Once the power supply and, subsequently,
communication have been resumed, the output relays arrive at the preset state.
If communication between the Wi-Fi relays and the cloud is lost, the CHECK DEVICE message
is displayed on your smartphone/tablet for approximately 1 hour. The Wi-Fi relays attempt to
resume communication throughout. If you attempt to switch the output relays while no
communication exists, the system will display the message “Relay-Cloud connection is not
valid” or “Communication to relay has been lost” to inform you that the command cannot be
executed. Alternatively, the message “Relay is not responding” may be displayed to inform you
that the relay did not sent status change acknowledgment to the cloud.
If the reconnect notification switch is ON, you will always (also after a short failure) be
informed by notification that communication has been resumed.

6. Notes
6.1. The Wi-Fi relay maintains constant connection to the cloud for its performance. This
connection uses many tools that are beyond your view control and can suffer from failures with
various durations (AP, Ethernet, servers, etc.). If the Wi-Fi relay connection to the cloud is lost,
the Wi-Fi relay will pass to its safe state: the output relays are either switched off or remain in
the last state selected (see setting 3.3.c). If, for any reason, Wi-Fi relay communication with the
cloud is lost for longer than 1 hour, a connection loss message will be sent to your
smartphone/tablet. The Wi-Fi relay will make repeated attempts to reconnect during that time. If
connection between the Wi-Fi relay and the cloud is resumed after the fault has been
eliminated, the output relays will switch to the last status selected.
6.2. The Wi-Fi relay can be controlled from several smartphones/tablets if present in their
application. The Wi-Fi relay will switch to the status sent to it (the most recent status is valid
irrespective of the device from which it was sent).
6.3. The status of the Wi-Fi relay outputs is displayed in all the smartphones/tablets that have
this relay set. However, if communication between the Wi-Fi relay and the cloud is lost, the
status existing before the loss is displayed ( automatical set to NO / OFF state after
communication lost or after power down will not appear to relay state and relay history )
6.4. When App repeatedly displays communication error and internet is working, kill the App
on background and run it again. You can do this if you press Home button twice and swipe App
Amart4house up.
