Thanks Gary, looking at that.
Tried to keep things as simple as possible at the esp32 end, (which by the 
way is an amazing piece of kit for $10). So it is sending very raw data - 
number of clicks from the rain bucket, number of revolutions from the wind 
cups, for example. The python program then converts this into sensible data.
If I need to make any changes in the esp32 it needs to be physically 
connected to the pc using the Arduino ide, which is a pain. Also wanted to 
make as few demands on it as possible until I see how stable it is. But so 
far so good.
If it stays stable will try the direct mqtt driver.
