I have recently bought a whisper to complement my Netro watering system. It was bought from Amazon, but showed no signs of life after following the instructions. I have left in the garden presuming it was flat. After a few day the unit is still showing a red light suggesting the battery is still not charged . Is the unit faulty?
Although the app tells me I’m on line my sprinklers will not activate. I’m not sure if there been a recent update, however had the same problem last year with firm wear. I’m based in the UK, so not sure if this makes a difference
