Humidity

[xgfreon]

I am trying to trigger a program based on the humidifier running. The humidifier active always just shows a 99 running or not.

Is the thermostat indicating correctly? The little water drop icon on the top icon bar will turn from blue to orange when the stat is calling for humidity. Same for the water valve on the humidifier, is going on and off in sync with the light and values from the stat?

There's also a setting for humidity on demand, do you get that behavior on both heat calls and humidity calls?

The only thing the plugin does is set the Humidifier Active (GV2) driver from the "hum_active" variable in the query response from the Venstar API:

self.setDriver("GV2", int(thermoState.get("hum_active", 0)))

That's the sole line of code that touches the GV2 driver. If no "hum_active" is present in the API response, the GV2 value defaults to 0. The GV2 driver is defined in the profile as a Boolean (0-false, 1-true). Here's the API documentation description of the "hum_active" value:

hum_active

Humidifier active 0: Off 1: On

The only way a value of 99 could show up here is if 1) something in the Venstar API is broken, or 2) something in IoX or the ISY Node Server API is broken. I'm betting it's the former.

Yes I was hoping it would just report status off or On. Just stays 99 when off or on though   I have had these for years but never messed with humidity settings in ISY until recent so I cant say how it reported in the past.

@xgfreon Do you have the Venstar Skyport app? What does it say about humidifier active and dehumidifier setpoint?

[hart2hart]

I use humidity control and the values for Humidifier Active are True and False as Goose describes.

Do you have the Thermostat setting for Stages and Outputs then Aux Output Stage set to Hum?

[xgfreon]

I do and here is the dash for humidity. I see there is a dehumidify options and there is a 99% in that box, i wonder if that is the data being populated there.

[xgfreon]

after changing that dehumidity setpoint i can confirm that value is what is being imported to the humidifier active box.

[Goose66]

The problem is with the API on your stat. But according to hart2hart it’s working on other stats, so we can’t just patch it. You may want to see if there is a firmware update available for your stat that you could try.

[xgfreon]

also I have 5 of these thermostats, only 2 of them have Humidity option and I notice the other one seems to be importing correctly though this is not the one connected to my humidifier.

I was going to ask which model of Venstar CT do you have, there are models with and without a humidistat

the living room which is the problem is the t7900 firmware says its up to date.

looks like the quickest fix for my case is just swap these 2 stats and call it a day.

[Goose66]

Both thermostats are T7900s, and one's working and one is not, correct? Are they showing the same firmware? Can you rollback the T7900 with the problem to a previous firmware version?

[hart2hart]

Only as a point of reference, I have 3 7900. They all have 6.93 fw (which is the latest & been that for years) and function as desired.

[Goose66]

May be a memory corruption problem in the offending T7900. Maybe a factory reset and reconfiguration?

[xgfreon]

Actually looking at this non workin 7900 the firmware is older but using the built in firmware updater says its up to date. 

these things are a pain to update lol, cant find a small enough sd card so waiting for the amazon delivery to try and update manually. Will report back after that!

[xgfreon]

As luck would have it, neither of my 7900's will recognize any sd card.  My 2 5800's recognize and read/write to the sdcard just fine. I guess i'll have to contact venstar and see if they have any ideas. 

do any of you happen to have the older colortouch connect software that you used to be able to actually program the stats in the software and then upload the schedule to the cards? The only version on the site no longer does that. The old version also used to have an sd initialization wizard. Not sure that would help or not.

[Guy Lavoie]

Last spring, Venstar actually shipped me a SD card to perform updates on my three T7900s, for free. The online updates don't seem to be functional anymore.

[xgfreon]

yea they are shipping me one as well.....guess we will see if the magic card works

You can't fault their support, though I did report a bug last April and it hasn't been fixed. Maybe they're waiting to incorporate a fix into their next update. The bug is that if you have an external temperature sensor and set the thermostat to use it as it's operating sensor, the thermostat works fine. But if you ask Alexa what the temperature is, it gives you the temperature of the thermostat's internal sensor.
