Thermostate with Humidity Sensor Error Reading

[bktong]

All,

 

FYI. I have been working with Michel offline for the past few days. I granted him access to my ISY. We have determined that my PLM is NOT sending acknowledgment when a manual query is issued. This only happens when the Thermostat Mode is on Program Auto or Auto. For the rest of the other modes such as Off, Cool, or Heat, manual query is fine and the PLM is able to get the correct acknowledgments.

 

I will replace my PLM 2412S and of course will do more testing.

Billy/Michel,

 

I tested your proof (Billy) and you're right. When my upstairs thermostat is in Program Auto and I perform a query, I get 144%. When I put the upstairs thermostat in any other mode, I get 3%.

 

Now why I get 3% when I should be getting something more like 43% is another story...?? But I also don't have the humidity dongle, so maybe I should just be ignoring this reading altogether?

 

Reason I bring it up is because I have another thermostat downstairs, also without the humidity module, yet it reads the correct humidity all the time, in any mode (presently at 45%).

 

So riddle me why the downstairs thermostat returns the correct humidity while the upstairs doesn't?? Thoughts?

 

(BTW - incorrectly reading upstairs thermostat takes 2 hops to the PLM, while the correctly reading downstairs thermostat takes 1 hop to the PLM, according to event viewer. if that makes a difference)

Maybe I should have just removed my last post. I'm a moron. I actually have a humidifier connected to my downstairs HVAC, but as it has manual dial controls on it, I wasn't thinking that it could possibly be reporting humidity to the downstairs thermostat. And I don't have the Venstar humidity module either, so methinks now that the humidifier is actually smarter than I gave it credit for and is actually reporting humidity to the downstairs thermostat.

 

That would also explain the 3%/144% reading on the upstairs thermostat - there's no humidity module OR humidifier upstairs. So that's why I'm an idiot.

 

I just bought two humidity modules so I expect the downstairs t-stat to continue reading accurately, and the upstairs t-stat to at least be giving me ambient humidity once I install the module there. Am I getting this right?

Hi kaplansa,

 

Yes, you are correct. Once you install the humidity modules, you should be able to get humidity readings for both of your thermostats. The only word of caution is that only the 7 day programmable thermostats supported humidity (as far as I remember).

 

With kind regards,

Michel

All,

 

After months of exchanging out hardware and software upgrades, we have finally found the cause of the problem. It was due to either a bad PLM (2412S) or incompatibility of PLM version to the thermostat T1800 V2.

I replaced with 2413S.

 

Thanks for Michel and the UD team. I think we all have learned a lot from this experience.

 

Now, I can get correct humidity reading every time.

 

Thanks,

Billy

Hi Billy,

 

This news is bascially the highlight of my work-week!!! Thanks so very much for the update and your patience throughout the troubleshooting.

All,

 

I have had the same issue, one thing that I tried was to select "cool" instead of "auto" and the problem clears. Once I select "auto" again then I get a humidity value to be double the cool temp setting.

Hi Greg,

 

What is the firmware version of your thermostat?

Same here. I get humidity value twice the cool setting when I do a query. If I don't do a query I never get automatic humidity updates. This is with the new v.22 adapter. I gave up on it and removed the humidity sensor.

Hello all,

 

I have submitted a query to our tech rep at SmartHome. I shall keep you posted.

Hi Greg,

 

What is the firmware version of your thermostat?

 

With kind regards,

Michel

 

 

Michel,

 

It is a Rev. 2.2, it is the integrated 7-day thermostat.

Hi Greg,

 

Thank you.

 

Just got one of those thermostats and will try to duplicate and provide feedback .

 

With kind regards,

Michel

I also have the new 7-day integrated thermostat w/ the humidity module. My thermostat is rev 2.2 build 1810. I checked and my humidity is being correctly reported regardless of Thermostat Mode.

 

However, I am not receiving updates from the thermostat automatically and have to use a program to poll it every few minutes to catch changes. I am running 3.1.6.

Hello H2R,

 

This should also be fixed once we start playing with the unit.

The automatic updates for humditiy don't work with the new thermostat adapter (V2.2) for the T1700 thermostats either. Also, a query sometimes returns a humidity value of twice the cool setpoint.

Michel,

 

Update:

 

First one still has issues in Auto mode with humidity sensor.

 

Upstairs unit

V2.2 Build 1310

 

Receive new thermostat for downstairs unit today and it appears to work perfectly with sensor (removed humidity sensor from upstairs unit).

 

Downstairs unit

V2.20 Build 4010

 

Set upstairs in auto and it reports humidity as double the set cool temp

 

Bad thermostat firmware version?

Hi Greg,

 

That's quite possible. I am going to forward this post to our reps at SmartHome.

 

Thanks so very much!

Michel,

Since receiving a replacement T8000 Rev 2.2, build 1310 adapter a couple of weeks ago, the only time the Tstat reports humidity now is during the regular 3:00 AM Query. The Tstat with the previous rev 2.0 adapter frequently reported Humidity (often too frequently).

[Michel Kohanim]

wrj0,

 

Known issue with the current thermostat firmware version: humidity reporting has to be explicitly set. We are adding support for this command in the next release.

 

With kind regards,

Michel

[wrj0]

Thanks, Michel. I was wondering about the rev 2.2 build 4010 version of the thermostat adapter reported above and if it may have included the humidity reports that used to be sent in rev 2.0. I'll look forward to testing your next release.

[Michel Kohanim]

Hello wrj0,

 

As far as I know humidity reporting is disabled by default. And, you cannot set this setting if you have a thermostat without a sensor. And, finally, there's a known issue with the current thermostat firmware to report humidity x 2.

Correction: humdity reporting Cool Setpoint x 2

[wrj0]

Thanks, again Michel. Not trying to get under your skin, just wanted to report my observations.

 

I do indeed have the Humidity Module installed in the T1800. And, the HUM/NOHUM jumper in the T1800 is set to the HUM position.

 

Previously, when the rev 2.0 Insteon adapter was connected to the T1800, frequent humidity updates were received, as observed on the Thermostat page in the ISY Admin Console, and in the ISY log. With the Rev 2.0 adapter, anytime the humidity value changed, the ISY log recorded a Thermostat, Humidity, value, time stamp string. However, since installing the Rev 2.2 (build 1310) replacement adapter, it now appears that the only time Humidity reports are received is when a query is performed. Since an update to ISY rev 3.1.6 was performed about the same time as the new adapter was installed, my question really was if the Rev 2.2 adapter was causing the humidity reports not to be sent. It appears so. In looking into the ISY log from before the change of adapters, I find that with the rev 2.0 adapter, humidity reports were being received several times every hour throughout the day. But, after connecting the rev 2.2 (build 1310) adapter, humidity reports are now only received after a query.

 

Please note: with a rev 2.2 (build 1310) Insteon adapter, I have not observed the double value humidity as Pgeengr reported above with his rev 2.2 (build 4010) adapter.

[Michel Kohanim]

Hello wrj0,

 

No problem at all. Yes, with new INSTEON firmware, there's an option to send humidity reports (instead of having to solder something). We added support for it and just waiting for verification from SmartHome on the correct bit to set (bit 2 or 2nd bit = bit 3).

 

With kind regards,

Michel
