The main remote station is a commercial unit I have been busy reverse engineering it’s various sensors, it worked out the cheapest way to get all of the items as well as a suitable mounting enclosure. See this photo, the red circled area is where the original wireless coil antenna would be located so if I can use the HC12 with the standard coil I will locate it likewise there. I could have used the included inside display module but I wanted to use a PM and Create my own which also accesses the internet for official weather readings and forecasts using openweather plus there is no comparison between the mono LCD and bland display of the commercial unit to a PM with 3.5” TFT. I will keep you posted on how it performs I am just awaiting a DHT22 to arrive then I will hoist it up the pole and give it some tests. Thanks again, Regards, Mick
