The I-TOUCH gateway is required to be installed when connecting more than 35 I-TOUCH panels in 1 installation, or to access the I-TOUCH home automation system via a mobile application on a smart device.
The maximum number of panels linked is 125, with up to 4 gateways in any one installation.
The raspberry Pi unit connects to your local WIFI modem via a LAN cable It operates by linking the ITOUCH panels in the network via a WIFI connection. As long as your smart device is connected to your local WIFI network in the home you will have access to operate the I-TOUCH system.
When the local WIFI connection to your smart device is lost your smart device will operate via 4G through an MQTT broker to access the I-TOUCH system.
This method of priority of operation guarantees the faster response time with undiscernable delays in switching when connected locally ensuring that commands are not “lost” during transmission.
