Michel - I would have pulled out all my hair had I not found this thread! The behavior of the "3-way" checkbox is definitely reversed. I conducted "black box" testing (observing behavior only - no reference to API docs, ISY logs, etc.) using a Micro On-Off module and a switch. All I had to go on was the Smarthome product documentation http://www.insteon.com/pdf/2443-x22.pdf describing how the 3-way mode is expected to work. I would ask that you please hook up a Micro module (On-Off or Dimmer) to a toggle switch and test it against the Owner's Manual. Adherence to the API docs is moot if checking the box does the opposite of what the user expects based on the user documentation. Thanks in advance, Peter

Thanks, Michel -I find that the program as I've written it If Status 'Filter Pressure Switch' is On And $Filter_Clogged_Msg_Sent_Today is $FALSE centralizes both conditions in one place and is completely self documenting, so thank you again for variables! Peter

I have a program which alerts me of a condition. I only want 1 message per day, so the program tests the value of a flag variable (reset @ midnight by another program). Would enabling/disabling the main program be significantly more efficient than using the flag? Thanks, Peter EDIT: I should mention that the condition I'm checking (back-pressure indicating that a filter needs changing) should only occur once every 12 - 18 months. When it does there may be a period of several days (to several weeks if I were out-of-town) before the filter is changed, During this time, the pressure switch would close & re-open every 5 - 10 minutes when the pump cycles. All the rest of the time the main conditional test (Insteon status = ON) in the program would be false. Do I understand correctly that until the ON event occurs, the program never actually runs?

What more can one ask for! Thanks, Michel. Peter

Michel - Since Spring is in the air, now's the time for implementing irrigation systems. Any chance this will make it into a 3.1.x beta? Thanks, Peter

Michel - This is great news! Glad I could help. I really do believe that having a sophisticated yet user-friendly irrigation capability which leverages the ISY's existing capabilities (location awareness, climate module, etc.) can be a significant differentiator against competing HA controllers. I'm building out my HA system now in stages, and will be tying in the irrigation over the coming weeks before spring arrives. I look forward to beta testing this functionality. Peter

Michel - It took some digging, but here's what I've been able to find. On this UN FAO page: http://www.fao.org/nr/water/eto.html is a public domain program for calculating ET. Among the program's downloads is the reference manual. This manual (which has no copyright notices that I could find) reiterates that the software is public domain. One of the chapters in this manual lays out all the formulas used in the program including the FAO Penman-Monteith equation. It would seem to me that if the software is public domain and the accompanying (non-copyrighted) documentation spells out the algorithms used, then those algorithms must themselves be unencumbered so reimplementing them elsewhere should be completely legal. Have a look and see what you think... Peter

Michel - First, thanks for the prompt reply. While I can understand where the various papers published which cite the algorithm would be copyrighted, I can't comprehend why the Food and Agriculture Organization of the United Nations would adopt and recommend an algorithm which would not be freely available. Are we certain that the algorithm itself is copyrighted under a "closed source" license? Peter

Michel - I'm considering using my ISY-99i to control irrigation. Before I purchase EZFloras... Has this calculation ever been implemented? Where would one see it w/in the admin console? I haven't purchased the WeatherBug module yet. Will I need to have this installed to see the ET calculation results? Thanks, Peter PS - Love my ISY. Way to go UDI!
