I am faced with a partially failing Raymarine wind transducer at the top of my mast. It is from the ST series vintage, and was originally connected to an ST60 wind display.  I am using an ITC-5 converter which is directly connected to it (and it alone) to get the data onto my NMEA 2000 network where everything else happily consumes the data. 

I am already having to drag new cable for my VHF radio to the top of the mast, and it is proving very difficult. I do not want to step the mast right now to fix this.

As a result, I am looking for wireless wind sensors that could fit the bill. I am not a racer, so I don't need any crazy features.

I originally had Tacktick wireless sensors on another boat, which Raymarine bought a few years ago. They did not perform well due to interference, and had a lot of trouble with the solar charging wind instrument failing repeatedly. It doesn't look like Raymarine has done much with that product line other than slap their logo on it.

The Garmin GNX looks pretty close to what I want, but I would also have to add a GNX wind instrument which would connect to it wirelessly, and then convert the data to put on NMEA 2000. That's not the end of the world, as I could displace one of my Raymarine i70s displays - they don't have great sailing/wind features anyhow.

I've looked at other smaller manufacturers but haven't found any that seem that great. Are there other manufacturers that I am missing?

Ideally it should be wireless and either provide native NMEA 2000 or have a way to send it.
