Yup I migrated everything to v5 in the spring as is and the -32 and *0.5555 went with it. The program was in a disabled state because no need for a Humidifier during the summer. I decided this week to get it going but it was spewing wacky results. So I made a small test program for this post. Reboot - I worked in IT for 20 years so reboot and power cycle were the first things I did. Changed and saved many many many times. Copy and Paste this code references the Polyglot/ISY Weather Service Device <?xml version="1.0" ?><triggers><d2d><trigger><id>33</id><name>Temp Calc</name><parent>1</parent><if></if><then><var id="1" type="1"><op>EQ</op><status id="CLITEMP" node="n002_wu" uom="17"/></var><wait><seconds>1</seconds></wait><var id="1" type="1"><op>SUB=</op><val prec="0">32</val></var><wait><seconds>1</seconds></wait><var id="1" type="1"><op>MUL=</op><val prec="4">5555</val></var><wait><seconds>1</seconds></wait><notify content="21">1</notify></then><else></else><comment></comment></trigger></d2d></triggers> Thanks again1

For testing this is entire program, can't be any simpler. No triggers, just a right click and Run Then. The first line is the Polyglot/ISY device that holds the outdoor temperature. The actual program is disabled for now until I get the F -> C working again. So if TempC is assigned to the value of the Polyglot/ISY value the calculations are ignored. If I manually assign TempC it works perfectly. It's weird : )

Thanks I posted the Notification values further up in this post and they correspond to the values in the Variables/Integer table. If there was a state variable it was a mistake as all of the variables were supposed to be numbers and should be in that table.

This is the output of the calculation using the Polyglot/ISY device, which is the same as the input. Let me know if I've done this incorrectly. And if I manually assign it, this is the result which is correct I used to be a programmer, but there sure is something strange about this behaviour Anyway thanks!

I think I see what you mean but this simple program has 1 variable that is declared as an integer. The reference to the Polyglot device that holds the temperature data is likely causing the problem because manually insert the temperature works fine. Maybe can you point out in the test program above that could cause the problematic behavior?

Thanks, I have roughly 30 state variables some that are set by apps like Blue Iris, Alarm system, etc and others that trigger various things like google asst and alexa through the portal. I have 1 integer variable (for this test) that is assigned but not working properly as I described above. I deleted and recreated the program but still not working.

Sorry I should have mentioned variables were declared as Numbers with precision 1. By non-triggering variables you mean numbers? Maybe I'm missing something?? Thanks!

So, my problems continue to persist – sorry! As mentioned, I use a Weather Service to provide the current outdoor temperature in F - currently it's 15.5F My testing yesterday used a manually inserted 15.5 F in a Program then performed the necessary calculations to get to Celsius which is -9.1 C *this is where I thought things were fixed. And the Result Excellent! *This is where I figured everything was fixed* However, when I reference the Polyglot / ISY Device variable that the Weather Service provides the calculations stop working. Below is the correct temperature as displayed in the ISY Devices. Below is the Program that converts the Temperature supplied in F to C. Note the only change in the Program is the first line. And the Result Seems you can assign the temperature to a variable but then you can't touch it. Has anyone seen this before? Thanks!

No worries, once I knew the feature was there I did some quick playing around with it. Prior to recreating the Program, changing precision didn't do anything - the arithmetic result was always the same. After recreating it worked perfectly - both results and precision. Fortunately this is the only program that had any amount of calculation in it. I suggested further up that the Integer Tab is misleading and probably more appropriately should be identified as a Numbers tab.

I suspect it would work. Thanks for the follow up!

I noticed that as well. A couple of times I went to the Notifications area after creating the variable and I would get the Row/Column reference instead of the Variable name.

Just to close the loop on this post, this is the result of the recreated program. The code is the same but I added Wait 1 sec to be sure. Btw references to set point is the humidifier control to avoid window sweating - yes, it's that cold and snowy. (where is the global warming!) Indoor Temperature: 20.9 C Humidity: 27.0 % (Set Point 30%) Outdoor Current Temp: -9.2 C (Set Point -5 C) Forecast Temp: -13.5 C (Set Point -10 C) Humidity: 53.0 % Thanks for all the help!

That fixed it perfectly - thanks!. I think the Variable/Integer tab should be renamed Variable/Numbers - makes more sense Thanks again!

Thanks maybe I'll try an update. Are you running the RC1? Update 1: Update didn't help. I'll delete and recreate the Program Update 2: Deleting and Recreating the Program worked - all good

I put waits but no change. This is the Program with Input, Calculation and Output with the result of each step Input Temperature = 15 Calculation according to ISY Temp_Current = 0 ----->result---> (initialize to 0, not required but did it anyway) Temp_Current = Temperature ---->result----> 15 (initialize to current temp and this is correct) Temp_Current =- 32 ------>result-----> 15 (15 - 32 should be -17 and is step incorrect) Temp_Current =* 0.5555 ------ >result------->15 (-17*0.5555 should be -9 and this step is incorrect) Output Temp_Current = 15 ----> result ------>15 (should be -9) Not sure how I can make it more clear Thanks

So my arithmetic is fine and it corresponds to your, but the code isn't working. Maybe I'm missing something, this should be simple Thanks!

I wonder if anyone can help me and thanks in advance for any suggestions. I want to do a simple conversion of Fahrenheit to Celsius but I'm not getting the calculation behavior I expect from the ISY. Below is the calculation. Note I added Notify statements to track progress of the calculation. The Variable $Temp_Current is defined as an Integer. I would prefer floating point but it seems it's not available. The initial Temperature is supplied by a weather service which is retrieved through my Polyglot. Initially the Temperature is set properly to 15F in both Polyglot and the ISY When the Program runs the calculation to subtract 32 it results in 15 Then the calculation to multiply by 0.5555 it results in 15 So the final Calculation results in$Temp_Current = 15C which is wrong, it should be -9C (or so) Any idea where I'm messing up? Thanks !

I think your initial statement was confusing...

Not sure it helps but my rest command from Blue Iris to the ISY via http looks different: http://user:password@192.168.0.69/rest/vars/set/2/38/1 I also use similar rest between my alarmserver to set 15 variables in the ISY and commands are almost instant and has worked for years... mike

Can Can someone expand as to what the very standard method is? I have the same no IP problem using the ISY Launcher (start.jnlp) as well as the previous launcher. Roughly 20% of the time it comes up blank. I've been using an ISY for years and it's only in the year or so that this has been a problem. The problem is only on desktop PC, my laptop works perfectly every time. My PC runs on two subnets 192.168.0.1 as the primary internet connection and 192.168.1.1 for a 10Gb ethernet connection to a video server (no gateway). It's not a big deal but was wondering if this "very standard method" was sending the frame down the wrong pipe? mike

Hi, I'm just finishing up something similar as and our cheap humidistat never worked properly. Highlights below: - Note: electrical for the furnace blower also supplies power to the humidifier transformer - Polyglot MQTT and a dht11 multi-sensor for inside temperature and humidity Only run humidifier only if inside humidity level is too low Polyglot updates an ISY multi-sensor - Polyglot MQTT and Weatherunderground for outside current temperature, 1-day forecast low temperature Only run humidifier if outside temperature conditions are satisfactory to avoid window condensation which is a big problem in our area of Canada The 1-day low is used to allow time for the house to dry out Polyglot updates another ISY multi-sensor - Wrote a very simple ISY Program to control an IOLinc (NO) to turn on the humidifier When inside humidity (<25%), and outside temperature (> +5C), and forecast temperature (> -10C) conditions are satisfied This program automates a routine I used to manually set the humidistat (basically On or Off) - Bypassed the POS humidistat The most challenging part of this setup was F/C handling in the ISY. mike

There is Python-based open source sw programs available online that can be used to build a little alarm server on a RPi. An Envisalink is also required to network enable the ADT system. Basically the alarm server triggers variables in the ISY through the network module which can trigger ISY programs.

Handy in a big house...

For example: DSC armed -> Envisalink -> Alarm Server -> ISY variable -> ISY Portal -> Alexa Notification "Alarm armed"

Eyezon has a web app and i see there's one for the iPhone as well although i've never used it. Eyezon will do the monitoring for you as well. I built my own alarm server that interfaces with my isy but the Eyezon web app is handy too...
