Dear Blick, Herb, and WeatherCat Davis troubleshooters,
Alas, from around 7:30 pm to 10 pm I once more lost transmission between my console and Weather Envoy. This is extremely maddening since I can check the console under such circumstances and the data is there. It simply doesn't make the extra 30 feet to the Envoy and WeatherCat. In the past, I have power-cycled the Envoy to restore the connection, but this is a bad idea because you lose data like the ET and rainfall for the whole year.
At 10 pm I got fed up and decided to try something else. I changed the ID that the Envoy was expecting to receive the signal from #8 to #7. After a moment, I reversed the procedure and put it back at ID #8. Within a few minutes, the Envoy was once more receiving data.
That suggests to me that the firmware in these Davis devices isn't particularly good at recovering from a loss of transmission caused by some sort of EMI/RF interference. So if you find yourself in this sort of predicament, you might try "giggling" the IDs of the receiver to see if that gets to try to find the signal more rapidly than if you just waited and hoped. If your problem is between the console and the ISS, at least this procedure doesn't require going outside to perform it.
Cheers, Edouard
