As far as I know, it is a good trick, it would be a good improvement to create a 3V remote battery set to enhance the life of the existing set of 2 x AA. I preferred the hardwired high return rate that i get and just extended cables by 30m or so. The anemometer is now fully shielded and earthed and runs perfectly. The signal into the house from the Hygro/hub must be low impedance and works much better but I have run a cat5 for that, just need to put tails on both ends. Power is fed from the linking cable direct from the console.
