Advice on Thermostat with remote humidity/temp sensors

igors.micko · January 5, 2021, 9:58pm

Situation is: i have a heater and temperature sensor.
How do (can I ?) combine them to "thermostat" and control by Thermostat Controller ?

Install Thermostat Controller. Pick the real connected thermostat, then pick your connected temperature sensor as the remote sensor.

A virtual Thermostat with the same name as your real Thermostat will be created with “Controller” appended to its name. You change the switch in the app from Free to Controlled. Now your real connected thermostat will use the set points of the virtual thermostat.

Have NO real thermostat. But heaters controlled by relay and temperature sensors.

SmartHomePrimer · January 6, 2021, 2:40pm

Create a Virtual Thermostat on HE
Setup a very simple Rule Machine rule that uses the condition of the virtual controller device's custom attribute thermostatOperatingState , then you can have it turn your heater ON when the Virtual Thermostat Controller value = "heating" and turn if OFF when the value = "idle".
Name it in the device label.
Add the Hubitat Virtual Thermostat to a new Thermostat Controller child app.
Select your temperature sensor(s) as the remote temperature sensor(s).
It will create a device named with your Virtual Thermostat's name, and the word "Controller" appended to it.
Change the switch in the app from Free to Controlled. Now your virtual thermostat will use the set points of the thermostat controller and the remote sensors as input for the thermostat hysteresis.

Looks promising. Will check as soon as posisble and provide a feedback. Thank You very much.

I'm interested in your hack driver version because this thing (tuya sensor) reports only when it feels like it which has nothing to do with temperature nor humidity change.

RNoia · March 20, 2021, 1:08am

Curiously, on a whim I reverted the driver for this to the generic zigbee one and it’s working perfectly fine. I’ll do some flip flopping and see if there’s actually a difference and will post my hack.

RNoia · March 21, 2021, 12:55am

So with the standard Zigbee "generic motion/humidity sensor", I get the following readings, which appear to be roughly every 5 minutes. I'll switch the driver and report back for the other one (the publicly posted sample driver that I modified):

Here's the modified driver. It's been a while, but think the change had to do specifically with the humidity line.

I just checked my logs again and for the entire duration of the day today whenever the temperature or humidity is constant (unchanged since last time) there does not appear to be an event. You can force it with the little button the device, however.

ymerj · March 21, 2021, 3:04pm

Thank you for help. I tried your version but unfortunately it does not change the erratic behavior of this device. It is true that pressing the button will update the readings but this is antithetical to an automation system point of view.

I wish there would be a setting to have the device update itself on a timely manner. The way it behaving now makes it totaly useless.

Thanks again for your effort. It is appreciated.

djh_wolf · March 21, 2021, 3:24pm

This,

I use temp probes (connected with nodemcu's/konnected), wired thermal actuators on the rads (again, nodemcu's/konnected/3V_relays), one zwave boiler switch and schedules through webcore. Works ace.

RNoia · March 21, 2021, 6:25pm

I've gone through my AC-powered environmental devices and they all behave the same, despite having power to report constantly/periodically:

Aeotec motion (mulisensor 6) sensor (which also does humidity) doesn't do constant humidity or any environmental sensing periodically - only upon change. Going through my logs, the AC reporting is 5-10 times a second (showing 100%). Lux, temperature and humidity only show up on a change.
My homeseer light sensor (which also does temperature), has a selectable polling temperature interval when ac-powered (not on battery). but the reporting behavior is the same - temperature only on change. I will admit this does seem a bit odd to me as well, especially since the polling is selectable.

However, I do think the Tuya device isn't as sensitive as it could be, I can see periods of no change, like when I take a shower, that it goes from 46% to 75%. But this device's battery has lasted over 9 months, so I'm willing to accept that.
