2108-03-06 So at our Men's Shed we often stop for tea around 10:30, turn off the tools, sit down for a chat and a few laughs, or maybe a tear or two. Our up-coming project is another 50 bat-houses for the Canadian Wildlife Federation which brings me to one of my present Pi projects. Now I don't want any solutions thrown at me here because I've been at it most of the day trying all the foolishness I could find on the web with no end in sight.
Last year I was looking in on a Winterized home which has a couple of sump pumps running in the cellar. I'd always wanted to do some temperature monitoring and when I found the Texas Inst. TMP107 probe on DigiKey it seemed to solve the problem for me of distance. Only to say that I now have a Pi Zero running in the kitchen with three daisy chained probes, each 25ft from the last one. i.e. one near the sump pumps, one on the landing and a third out the bathroom window. A log file for the day is generated at midnight ready to mail to me. Last year it was only a Pi-B so we had to plug in a laptop and SSH the files down. This year it's a Pi-Zero so I walk in with my Galaxy and before I leave SyncBot has downloaded all the data.
That says very little about the struggle I went through switching over to SystemD, implementing an Access Point and finally a hardware clock. I probably lost a month on each topic and would like here to thank SurferTim and the like for their due diligence.
As for the bat-house location, it has a WiFi connection and the log file will be mailed to me one minute after midnight. It was already doing that on my home network but then I foolishly updated the operating system and we knows what happens then! A third Pi(Bee) in the equation is now wired as an Access Point so I''ve made it look like the farm WiFi and can happily login from my Win7-laptop and my Galaxy. Unfortunately Pi(Bat) is no longer behaving and it's WiFI now has the "carrier lost" sickness.
It seems to me I was happiest on the beach watching the tide remove my sand castles, while in Pi-land there seem to be far to many gremlins lining up to do the same.
As for Pi(Bee), it is destined to return to a bee-hive installation where last year it captured temperatures of +20C inside one of the hives when it was -20C outside, I thought that little tit-bit was worthy of the effort.
