Telematics system for local district heating company. I've implemented a feature that allows you to select all devices on a map and set some values for all of them (devices from different manufacturers). Helped to recoup the cost of whole system after they had a leak and could remotely close valves in hundreds of devices in affected area, meaning they didn't need expensive liquid nitrogen freezing equipment to block pipes for repairs.
