These things are different and IHDs do suffer from network compatibility issues.
The majority of IHDs use the ISM allocation at 433MHz for communication with the current sensor, so they might not take kindly to being used within a few miles of Fylingdales. They seem to use very simple wideband receiver circuitry as well. My amateur radio station can generate about 6kW ERP at 432MHz and my IHD doesn't like that at all even though it's a good 100m from the antenna. A colleague's weather station has a transducer that uses the 433MHz ISM allocation. He can either use an IHD or the weather station but not both simultaneously.
