In Hawera I was approached by a farmer who was fed up having to travel across the farm to turn off a pump motor, then return to the “working end” to carry out a fix. He would then return to turn the pump to turn it on, return to the working end to find the fix was not right, and then repeat this procedure. Now he can stay at the working end and turn the pump on and off whenever he wants with a simple text message. The time saving is extraordinary.
The article below, which was published nationally, relates to a Taranaki farmer who was suffering considerable damage to a pump shed.
