Hi guys, I've just wired up a cheap Chinese wireless controller off of eBay for my pump box but I'm having interference problems. The controller has a great range to turn the pump on but once the pump is running the effective range to turn it off again is about 1m! If I disconnect the pump I can hear the switch of the wireless receiver happily switching on and off again at long range. Any help would be greatly appreciated. I'm even happy to buy another wireless remote controller but just don't know what to get now. Don't want to waste more money! Cheers.
