The client has 24 units, each consist of Fan and dome light. There is only one electrical line per unit set up at the time of construction of the place. Customers want to control and monitor all the units with a touchscreen-based KIOSK. 


In order to have a separate turn On/Off for the Light and fan, Engibrains offered a Wi-Fi mesh-based relay along with a touchscreen-based KIOSK to control and monitor all the units. Our team has developed this project from idea to enclosure ready. Our firmware engineers built software of Wi-Fi mesh-based relay node, Root node, and touchscreen-based controller. Engibrains also help clients with Field trials and commissioning.
