SX1262 868M LoRa HAT
Houston, we have a problem 		thumb nail

I guess this all starts with my son-in-law Andrew, loaning me a Davis Weather Station. It consisted of: 1) The suite of sensors that sat outside in the garden on top of a suitably positioned pole, 2) The desktop console that displayed the weather that it was recording, 3) A Data logger that could be plugged into the base of the console. The Data Logger also provided a USB link that could be used to download the recorded data onto a Personal Computer, and finally 4) a costly piece of software that could be used to download the data from the data logger and a) display it on a web page, and b) upload it to one of the web-based weather stations.

In no time at all I wrote my own software to collect the data from the Data Logger and display it on a web page. Subsequently I switched to an Open Source package (Weewex) to collect the data from the Data Logger in order to display it on my web page.

When I had to return the hardware to Andrew, I bought a Davis Vantage Vue weather station, a Console, and a Data Logger. After a couple of years I replaced the Davis Vantage Vue with a Davis Vantage Vue PRO 2. It is still sitting on top of a pole and the weather recordings still appear on the Console.

Here I should say that from day 1 the Data Logger was a pain in the butt! About a year ago it stopped working and since then I have been unable to present the recordings that come to the Console on my weather web page.

Now I am going to attempt to use a SX1262 868M LoRa HAT to capture the data the weather station has been and still is transmitting to the Console wirelessly. The list of links provided below is my reading list that I now have to work through.

Don't hold your breath!

... and again, as I wrote a second preamble
unaware that I had already written one ... ???

As you might have read elsewhere, I have been running a Davis Weather Station for some time. It consists of a suite of weather sensors (SOWS) that sit on top of a pole in the garden capturing wind, rain, etc data that is then periodically transmitted wirelessly to a console that sits on my desk. The console also displays the current that weather data in a meaningful manner. The received data is also stored in a flash memory that resides in a dongle that I plugged into the bottom of the console.

That data can subsequently be downloaded to a PC by connecting the PC to the dongle using a USB cable. Once the PC has the data it is invariable displayed on the PC and also uploaded to one of more web based weather stations where it is used to augment the data base the weather station uses to model/forecast the weather.

Unfortunately that forever troublesome dongle connection died about a year ago. Given its price and performance I will not be replacing it, Instead I am going to try and use a 833 MHz receiver controlled by my PC (or similar) to develop a system capable of capturing the weather data being broadcast wirelessly by the SOWS.

No need to hold your breath again.

If you have any comments, corrections, suggestions or plain criticism, I would appreciate it if you would communicate the same to me.

Money can't buy happiness, but it can buy a bicycle.
