I had looked at these and others but most seemed limited on what they
could learn, Tellstick looks a lot better and work with quite a few,
had a quick look but did not see "Status" ones listed.

I was also using this a a bit of an introduction into programming (even
at my old age!).

Will look into your suggestion when I get more time.

Thanks
