mountainman3520 Posted July 24, 2013 Posted July 24, 2013 Hello mountainman3520, Thanks so very much for the details. Quite enlightening! On Venstar thermostats (depending on the firmware) ISY can set the time and there's a command for it in the programs. On 2441TH, unfortunately, such facility does not exist. I am so very sorry. With kind regards, Michel Hi Michael. Thanks for the reply, and for the support of the 2441TH. So far you've included all the main, most important functions, even if a few are missing. It's allowing my system and programs to work great. Maybe put others like the time on your upgrade list? A few related questions, I guess more general programming questions: - How does the isy resolve slightly overlapping conflicting programs? Example: if time is between x and y, variable=1 and if time is between y and z, variable=0. What happens at time y? Which program wins? Will programs like this run reliably or is it better to make sure no conflicts exist by shifting the times off by a minute? - When using times, you have a choice of "same day" or "next day" etc. I have programs that are set to run until 12AM. Technically this is the next day but I have the same day option checked and it seems to be working as the same day, ie the program isn't running for an extra 24 hours. What is the isys definition of same day vs 12am? I realize I can avoid creating this uncertainty by ending my programs at 11:59pm and then it's clearly same day. - I have programs that use the date and run annually based on date. It looks like your date functions always require day month year, ie I couldn't figure out how to specify Oct 31 every year. Instead I had to make a long chain of oct 31 2013 or oct 31 2014 or .... am I missing something? If there isn't a way to specify the 4th of every month (month and year are don't cares) or every Oct 31 (year is a don't care), then please add this to your upgrade list. All the date and time triggers should allow fields to be set as don't cares in some nice consisted way. Thanks -Dan
Michel Kohanim Posted July 25, 2013 Posted July 25, 2013 Hi mountainman3520, My pleasure. I will have to defer the answer to these questions to higher authorities! With kind regards, Michel
Chris Jahn Posted July 25, 2013 Posted July 25, 2013 Hi Dan, - How does the isy resolve slightly overlapping conflicting programs? Example: if time is between x and y, variable=1 and if time is between y and z, variable=0. What happens at time y? Which program wins? Will programs like this run reliably or is it better to make sure no conflicts exist by shifting the times off by a minute? A single event can cause many programs to start running, and when this happens you cannot determine the order in which the programs run. In your case: - At time y / variable = 1, your 1st program will run 'Else', 2nd will run 'Else' - At time y / variable = 0, your 1st program will run 'Else', 2nd will run 'Then' - When using times, you have a choice of "same day" or "next day" etc. I have programs that are set to run until 12AM. Technically this is the next day but I have the same day option checked and it seems to be working as the same day, ie the program isn't running for an extra 24 hours. What is the isys definition of same day vs 12am? I realize I can avoid creating this uncertainty by ending my programs at 11:59pm and then it's clearly same day. We generally treat 12AM as morning (i.e. a day is 12:00:00AM to 11:59:59PM), but I think its better to use 11:59PM or 12:01AM to avoid any confusion. - I have programs that use the date and run annually based on date.

Unfortunately, you aren't missing anything; this feature has been requested for awhile and just needs to be prioritized above all the high priority items
mountainman3520 Posted July 27, 2013 Posted July 27, 2013 One question I do have is that the clocks on the 2441s drift a lot. Note that I don't use these clocks for anything since the isy controls the thermostat set points, and I'd turn the clocks off if I could, but I can't so it bugs me when they don't display the accurate time. I'd like to write an isy program to periodically set them to isy time, which is in sync with a time server. Anyone know how to view and change these other features of the 2441 from the isy? Wow! I have to correct my comment above. Actually, the ISY DOES include a function to synchronize the 2441's internal clock with the ISY clock!! Its very cleverly named "synchronize clocks". I'm not sure how I missed it before. Maybe it was added in a recent software upgrade. Anyway, I'm very pleased. I've now added a program that syncs the clocks of all my thermostats every day at 3am. Good work ISY hackers!

I ask because I was thinking of getting one but would want the clock to be updatable if it drifts quite a bit as I do plan to leave the stat in charge of doing the temp set backs most of the time, plus it's in a place where I do look at it for the time.

barrygordon Posted August 5, 2013 Posted August 5, 2013 Where can I find information on using the Insteon 2441TH thermostat with the ISY994? I am looking to effect complete control (setpoints (cool, Heat), modes (on off cool heat auto), fan (On Off Auto), etc. I would like to get event notification for any and all changes including current room temp. Just need a pointer to where this info is located. TIA, Barry
Michel Kohanim Posted August 6, 2013 Posted August 6, 2013 Hi Barry, I am not sure what type of information you are looking for. You do get all of those with ISY and 2441TH. With kind regards, Michel
barrygordon Posted August 6, 2013 Posted August 6, 2013 A simple example of a REST command to set a cooling set point, or the system mode ( heat, cool, off ) would help a great deal. I. Assume that if I make changes at the thermostat it will show up as feedback if I have subscribed to the ISY. If you provide an example just assume the thermostat has an address of 11.22.33 Thanks
LeeG Posted August 6, 2013 Posted August 6, 2013 Example of setting Cool Set Point of 80 http://192.168.2.2/rest/nodes/1D 6C D6 1/set/CLISPC/160 http://192.168.2.2/rest/nodes/11 22 33 1/set/CLISPC/160 Example of setting Mode Heat http://192.168.2.2/rest/nodes/1D 6C D6 1/set/CLIMD/1 http://192.168.2.2/rest/nodes/11 22 33 1/set/CLIMD/1
barrygordon Posted August 6, 2013 Posted August 6, 2013 Thanks lee, that should get me started. I am sure I will be able to figure out the rest (no pun intended).
barrygordon Posted August 6, 2013 Posted August 6, 2013 Okay, I found some of the documentation for the 2441TH, but naturally have a few questions Node Command: CLISPH, CLISPC It appears that you must set 2x the desired temperature. I assume this is to allow for a setting +/- 0.5 degrees CLIFS What is the paramater? Numeric (0= off, 1=on; or string "On" or "Off") CLIMD Same question, what are the legal mode setting parameters (Cool, Heat, Off, On as strings or numeric values, and i numeric what value for what mode. CLIHUM I assume this will be a returned parameter being Humidity (0-100) with UOM being % CLIHCS Is this the reply for Mode? What are the possible values? String or Numeric? CLIEMD"> This seems to be obvious ( 0 = Off, 1 = On) Will a get command bring back the desired value e.g. http://192.168.2.2/rest/nodes/1D 6C D6 1/get/CLISPC
LeeG Posted August 6, 2013 Posted August 6, 2013 Refer to the WSDK category in the forum. It has links to all the current developer documentation which includes all the REST options. The answers to all the questions are covered in the REST section. Node Command: CLISPH, CLISPC It appears that you must set 2x the desired temperature. I assume this is to allow for a setting +/- 0.5 degrees The thermostat interface is spec’ed to exchange temp in .5 degree increments. CLIFS What is the paramater? Numeric (0= off, 1=on; or string "On" or "Off") 7=On 8=Auto – there is no Off as that could damage the heating system CLIMD Same question, what are the legal mode setting parameters (Cool, Heat, Off, On as strings or numeric values, and i numeric what value for what mode. Refer to the documents in the WSDK for the various values. Too many to repeat from memory CLIHUM I assume this will be a returned parameter being Humidity (0-100) with UOM being % Yes CLIHCS Is this the reply for Mode? What are the possible values? String or Numeric? Indicates if the HVAC is Off, Cooling, Heating (versus the mode) CLIEMD"> This seems to be obvious ( 0 = Off, 1 = On) Not familiar with this one Will a get command bring back the desired value e.g. http://192.168.2.2/rest/nodes/1D 6C D6 1/get/CLISPC Yes
barrygordon Posted August 6, 2013 Posted August 6, 2013 Thanks for the assist. I believe I now completely understand it. I just have to write the code for the iPads to deal with it.
barrygordon Posted August 7, 2013 Posted August 7, 2013 I have gotten to the point where I can successfully receive feedback from the 2441 thermostat and process them on my iPads. I notice in the ISY admin console there are commands for moving the setpoint up or down one degree. Are there equivalent REST commands to do exactly that or do I need to send a new ST value that is higher or lower by 1 to effect the change? I noticed that all the variables of the thermostat state have CLIXX controls except for the room temperature. For room temperature the ST control return seems to show the value as opposed to some control such as CLITMP. Is this by design or an oversight? Also I do not see a control value for "Holding" which is a thermostat state. TIA Barry
LeeG Posted August 7, 2013 Posted August 7, 2013 I did not find a REST command to move the SetPoint +/- 1. CLImate ST is STatus. – not a mistake – all the Insteon device primary state is stored in Status. Guess temp is considered the thermostat primary state. My 2441TH does not have a Holding mode/state. What does Holding do?
barrygordon Posted August 7, 2013 Posted August 7, 2013 on my 2441 which is sitting in a test rig, there is a button called "Hold" I assume (need to RTFM) it does what most thermostats have as a Holding option. The holding option will keep the current setpoints and not allow for any setback type programs to operate. Generally used if you will be out of the house for several days and want to keep the house at a fixed temp, but not change any of the setbacks. On my 2441, the button is there but when pressed makes no change to the display so I suspect you are correct in that it does nothing.
LeeG Posted August 7, 2013 Posted August 7, 2013 The Hold button applies to Programs within the thermostat itself. The ISY has no support for defining/managing programs in the thermostat itself.
RichTJ99 Posted September 3, 2013 Posted September 3, 2013 So with the 15% off sale, is it worth getting the 2441TH? I keep reading about all sorts of weird problems. 2441TH @ 15% off = $127.5
LeeG Posted September 3, 2013 Posted September 3, 2013 It is 15% off when purchasing $500 worth of equipment.
RichTJ99 Posted September 3, 2013 Posted September 3, 2013 Thats a good point, either way Nest being $250 & the older Insteon solution being over $200 makes me wonder if its worth a try, though I dont want the system to go haywire. Really I am wondering if this is still a 'beta' product as people have been saying.
arw01 Posted September 3, 2013 Posted September 3, 2013 Black friday sale is normally 20% off on all insteon. Saving up for that one since all these other sales are just a tease. Ecobee myself, commercial version and the EMS module as well.
RichTJ99 Posted September 3, 2013 Posted September 3, 2013 So I should pass on this one then. I keep hoping to see reviews saying its working properly. I am going to end up caving at some point & getting a wireless honeywell. The problem is I have a total of 6 thermostats that I need.
