Wilo Net is a Wilo system bus used for establishing communication between Wilo
products:
ƒTwo single pumps as twin-head pump function
ƒSeveral pumps used with Multi-Flow Adaptation control mode
ƒGateway and pump
en Installation and electrical connection
16 WILO SE 2020-09
Bus topology
The bus topology consists of multiple participants (e.g. pumps, control devices and a
gateway) that have been connected in series. The participants are connected via a
shared cable.
The bus must be terminated at both ends of the cable. This is done for the two ex-
ternal participants. All other participants must not have activated termination.
Since the Wilo-Smart Gateway does not provide termination, the Gateway must not
be installed at the end of a bus line (Fig.2).
If only one pump with Wilo Net is installed on the Gateway, the termination only has
to be activated on the one pump as an exception.
All bus subscribers must be assigned an individual address (Wilo Net ID). Please be
aware that twin-head pumps in the Wilo Net consist of two participants, both of
which must be adjusted accordingly in the Wilo Net settings. This Wilo Net ID is set in
the respective participant.
For more detailed information on how to set the Wilo Net ID and termination on the
respective connected device, refer to the respective installation and operating in-
structions.
The Gateway is preset to Wilo Net ID “21”.
In order to establish the Wilo Net connection, the three H, L, GND terminals are wired
with a communication cable from pump to pump to Gateway to pump. Use shielded
cables for cable lengths ≥2m.
Up to 20 participants can be connected to Wilo Net1. Twin-head pumps consisting
of two participants. For twin-head pumps, please also be aware that a maximum of
5twin-head pumps can be operated in one Wilo Net segment. As well as the maxi-
mum of 5 twin-head pumps in a Wilo Net segment, up to 10 further single pumps can
still be integrated.
We anticipate that another 20 participants can be connected to Wilo Net2 with the
future software functions that are planned for the Gateway. The available Wilo Net
IDs are reassigned in the second segment, so they can match the IDs used in Wilo
Net1. If the participants are correctly connected to the Wilo-Smart Gateway and Wilo
Net IDs are correctly assigned, then the Wilo-Smart Gateway automatically recog-
nises the connected devices. The Wilo-Smart Gateway then automatically starts
transferring the data from the connected devices to the Wilo-Smart Cloud.
NOTICE
If Stratos MAXO is a participant in the Gateway, ensure that the software version
of the Stratos MAXO is at least V 01.04.00.00 or higher. If the software version is
01.03.xx.xx or older, the pumps require a software update so that they can com-
municate with the Gateway via Wilo Net.
Commissioning en
Installation and operating instructions Wilo-Smart Gateway 17
7.2.4 Gateway connection to the Internet
For the Wilo-Smart Gateway to reach the Wilo-Smart Cloud, the Gateway must be
able to connect to the Internet via the LAN2 connection.
To do this, connect the LAN2 connection with an Ethernet patch cable (with RJ45
plugs) to an Ethernet connection where the Internet can be accessed.
The Ethernet connection can be a network connection of a building installation which
provides access to the Internet.
However, it can also be an Internet router that provides Internet access via DSL or G4/
LTE, for example.
The Gateway requires some services and accessible addresses in order to be able to
successfully establish a pathway to the Wilo-Smart Cloud. If directly at an Internet
router, this will usually work without any further measures.
If the Gateway is to be brought into an administrative network, the following inform-
ation will help administrators to set up the network accordingly:
ƒDNS service (default setting can be changed: 8.8.8.8)
ƒNTP service (default setting can be changed: pool.ntp.org)
ƒiotqwupdate.wilo.com, protocol HTTP/HTTPS, port 80 and 443
ƒwilo-universe-p-ioth.azure-devices.net, protocol AMQPS, port 5671
ƒglobal.azure-devices-provisioning.net, protocol MQTT, port 443 and 8883
NOTICE
LAN1 connection is not intended to be connected to a network with or without
Internet access, but only for a temporary, local connection of a PC/laptop to con-
figure the Gateway.
The Gateway DHCP service may cause conflicts with another DHCP service when
connecting to a network. This may result in network disruptions (Fig.4).
8 Commissioning
CAUTION
When the Wilo-Smart Gateway is commissioned, it is possible to view the devices
connected to the Gateway via the Wilo-Smart Cloud and/or to change the operat-
ing states on these devices.
If you do change the operating states, this can lead to the devices no longer func-
tioning as intended.
en Commissioning
18 WILO SE 2020-09
This may also disrupt the functionality of an overall system that depends on these
devices.
To rule out such unwanted impacts of online control, the default setting for all
users was set to “read only”.
When these access rights are changed to “read and write” by the Gateway owner
or by an administrator appointed by the Gateway owner, a user is authorised to in-
fluence all settings and functions of a connected device online.
For this reason, write permissions may only be granted to experienced users who
are able to gauge the effects that changing operating states on the devices may
have.
In order to put the Gateway into operation and make it accessible to someone using
the Wilo-Smart connect app, the following requirements are needed:
ƒPC/laptop with wired Ethernet connection and a
ƒSmartphone or tablet with an iOS or Android operating system
PC/Laptop
The PC/laptop requires an Ethernet interface with IP protocol. The protocol must be
set so that the IP address is obtained via DHCP (standard configuration).
The PC/laptop is connected to the Gateway LAN1 connection with a network cable
(patch cable, RJ45 plug).
The Wilo-Smart Gateway is configured using a web browser.
The Wilo-Smart Gateway distributes an IP address from the address space
192.168.10.x/24 to the connected devices via DHCP.
The Wilo-Smart Gateway can then be reached via the address 192.168.10.1.
Enter “http://192.168.10.1” in the address line of the web browser in order to reach
the web interface.
Fig.1: Web browser
The Wilo-Smart Gateway status page can be viewed by anyone at any time, but the
configuration pages require a login. When in the delivery state, the login details are:
ƒUser: admin
ƒPassword: admin
Before accessing the Internet and therefore the Wilo-Smart Cloud via the LAN2 con-
nection, it is necessary to set the required IP protocols in the web interface.
To prevent unauthorised access, the password for accessing the web interface can be
changed in the web interface itself. This password only affects the local login to the
Gateway web interface via LAN1. The web interface is not accessible via the LAN2
connection.
Maintenance en
Installation and operating instructions Wilo-Smart Gateway 19
The LAN2 connection is secured thanks to an encrypted connection to the Wilo-
Smart Cloud, independent of this password. Apart from connections to the Wilo-
Smart Cloud, no other connections are possible on the LAN2 connection.
WARNING
The password cannot be reset!
When changing the password for the web interface, make sure that you do not
lose this password. It cannot be reset for security reasons!
Smartphone or tablet
It is necessary that the current Wilo-Assistant app with the Wilo-Smart connect
function is downloaded on the smartphone or tablet.
When starting the Wilo-Smart connect function for the first time, you must register
with a MyWilo account.
If you do not already have a MyWilo account, you can create a new account.
A Wilo-Smart connect function that is already prepared with a registered MyWilo user
is ideal for commissioning the Gateway. If you have already used Wilo-Smart connect
with the Bluetooth connection, this step is already completed.
During further commissioning, the operator takes over remote access to the Gateway
via the Wilo-Smart Cloud. This provides the user with access to the data from the
connected products.
However, the Gateway must first be connected to a Wilo-Smart connect user (MyWilo
account) in the app for this. This connection is established by registering the Gateway
in the Wilo-Smart connect function of the Assistant app.
The login uses a PIN that is provided in the app. The PIN is entered in the Gateway’s
web browser configuration when the Gateway is commissioned. The Gateway is now
assigned to the user of the Smart connect app.
This user now has the administrative access rights to the Gateway and can add other
users and assign access rights to them.
9 Maintenance
The Wilo-Smart Gateway described in these instructions is basically maintenance-
free.
