Receiver initialization question
#1
Question 

Hello everyone,
While waiting for the arrival of my Pro2 Compact, I have a question.

A quote from the Wiki-pages says this:
Quote:The first time a new receiver runs, it needs to perform a special initialization sequence. This initialization sequence ends after the receiver has received at least one data packet from each of the three main sensors (Temperature / Humidity, Wind and Rain). During the initialization process the screen will show three letters (T-W-R) that will change from Red to Green once the corresponding data packet has been received.
From the above, it is evident that if you don't have a Transmitter unit already working and transmitting data, the receiver will stay forever in the initialization sequence. This is why we recommend to anyone that is starting to build a WeatherDuino weather station, to always start by assembling the Transmitter unit first.
On subsequent restarts, the receiver also will remain in the initialization screen, until it receives data from the three main sensors referred above.

How I understand this, temperature, humidity and wind are probably reported faster/immediately to TX as those are likely to be present all the time (unless there's a sensor failure/disconnect, of course), but the rain gauge doesn't usually report anything until the rain collector tips over, since a tipping bucket-type rain gauge is just a simple Reed switch-operated circuit.

Correct me if I'm wrong here, but wouldn't this mean that if there's a power failure and once resolved, the init process will not complete until the TX receives a single pulse from the rain gauge and reports it to RX?

Hello J.Jantti,

The TX unit counts every pulse from the rain gauge and stores this value (its a 32 bit counter so don't worry about overflow). No matter its raining or not, the value of this counter is sent to the receiver every 31 seconds. So in the event of a power failure, once power is restored everything will initialize fine.
