Thermostate with Humidity Sensor Error Reading

Michel,

Hmmmmm. I upgraded to version 2.8.1 and the problem still there when I query the thermostat with the humidity sensor. The Console shows >150%.

 

Do you think it's my humidity sensor that's having a problem?

 

Does yours go to >150% when query?

 

 

Thanks.

Hi Billy,

 

I just tested it again at least 20 times and the humidity readings are always within 5% of each other after each query.

 

I do think the problem to be on the thermostat/sensor/dongle.

 

If you would like, I can give you access to our lab's ISY and you can test for yourself. If interested, please send an email to tech@universal-devices.com.

 

With kind regards,

Michel

Michel,

I pulled out and resat it but still the same result when query showing 158%.

 

Think the humidity module is bad?

LeeG and Michel,

 

Here is a fragment of a level 3 log when I do Query. It returned 154% and 30 seconds later, it returned 44%.

Hello Billy,

 

Excellent. What I need is the message right prior to the first message. You see, when you got 44%, the last byte of the message received was 2C (=44 Decimal). But, you didn't send the same message for 154. In case you try and you get:

Fri 09/10/2010 08:15:05 PM : [iNST-SRX ] 02 50 14.07.FB 12.9C.D8 07 6F 9A (9A)

 

Then we know that the thermostat is returning the wrong humidity (9A = 154 in Decimal).

 

In short, what you need to do is to check the last byte of the returned message (INST-SRX) which is Hex. Use your computer's calculator to covert the last byte from Hex to Decimal. If the calculated value is equal to what ISY reports, then the problem is either the dongle or the thermostat itself.

 

With kind regards,

Michel

I'll get the dongle exchanged out first before exchanging the thermostat.

 

I'll update you when I get the dongle swapped out.

 

Thanks.

Hello bktong,

 

Thanks so very much.

 

LeeG also had an idea that we are investigating:

Do you know what's the actual humidity reported by your thermostat? How far off is it from what ISY reports (obviously not anything above 100%)? And, is there any way you could verify this value against say WeatherBug for your area?

 

Thanks and with kind regards,

Michel

Billy,

 

The Insteon 6A Get Zone Information command being used by the ISY to Query values in the tstat adaptor returns temperature values that are X2 the actual value. The 6A command spec’s this characteristic. It means that temperature values require an X 0.5 conversion to get the correct temperature value.

 

Although the 6A command spec does not mention this for the humidity value it is possible that the humidity value being returned is also X2 the actual value and has to have the same X 0.5 conversion to get the correct humidity.

 

Knowing what the thermostat is displaying for the humidity value compared to the value being returned to the ISY with the 6A command (is the value X2 the actual value) may answer this question. It is further confusing because the values returned by the 6A command are in hex so they first have to be converted to decimal and then X 0.5 applied.

 

I don’t have a Venstar thermostat. Can you confirm that the humidity value being displayed on the thermostat is the “indoor†humidity.

 

Thanks

LeeG & Michel,

I am bit confused. However, I did hit Query and ran to check my thermostat reading on Humidity and it's correct where ISY/console shows 158%.

 

The ISY and the thermostat is about 30 feet away.

 

I did ordered a new dongle and it's coming. Should able to swap it out next week.

In the log when humidity read 154 the set point cool is 154.

Yes, doubled, which the ISY interprets correctly. But the humidity output apparently matches it exactly.

 

As with Michel I do not ever see this incorrect humidity reading. Hopefully the new dongle will correct this.

 

Rand

 

Rand,

I get the correct temp reading every time when I do Query.

Rand and Lee,

 

Got the new replacement dongle (2441V) today and replaced the old one. Still the same issue.

 

Like you said in the other post, everything is X2. I notice the humidity is exactly double the cool point setting. For example, the set point for cool is set to 79c and that's why I kept getting humidity reading of 158%.

 

Any thoughts?

 

Thanks.

Billy

Continued to test with both new and old dongles for the past few days. Same results. I have ordered another humidity module. That's the next device I will replace to try to solve this problem. And then the thermostat itself if the new humidity module does not work correctly.

 

I can replace all the parts but one thing I can't replace/fix is the ISY code if this causing the problem. Since the temperature reading and the humidity reading is always equal to each other, I still think it may be ISY.

 

Thanks.

Hi Billy,

 

I do apologize for the inconvenience. I know exactly how it feels to have to deal with erratic behavior (in the past 2 weeks, I've replaced my Sony laptop 6 times and perhaps have broken the world record).

 

Although it might be ISY but it's going to be quite difficult fixing it if we cannot reproduce it. I sure hope that the sensor is the issue.

 

With kind regards,

Michel

All,

 

So much for the new Humidity module. Another failure. I guess it's on to replacing the thermostat. After that, I will give up if it doesn't fix it. BTW, I have a hard time believing the thermostat is generating a wrong reading when everything else with the thermostat is working perfectly.

 

Perhaps after I exchanged the thermostat out and still not working, can I swap the dongle and the thermostat with yours, Michel, since yours are working. :lol:

Michel,

 

The new thermostat came today and swapped it out. Guess what...same results with the Humidity reading on ISY.

 

Still think it is one of the hardware?

 

I even took the Humidity Module out of the thermostat and put the jumper to 'No Hum' on the thermostat but ISY still shows 2x of the A/C setpoint.

 

Michel, what jumper settings do you have on your test thermostat for MISC1,2,3, humidity jumper, gas fan, O/B, HP/Gas?

 

Thanks,

Billy

Hello Billy,

 

I truly apologize for all the trouble. I have not changed any of the jumper settings on the thermostat.

 

What I would like to do is to give you access to our lab system so that you can test it out for yourself. We have two thermostats here one with a humidity sensor and the other without.

 

Would you be kind enough to send an email to tech@universal-devices.com and I'll provide you with the URL to our system?

 

With kind regards,

Michel
