Avatto has a new version of this this model, ZWT100-BH-3A TS0601 _TZE204_lzriup1j.

The new driver @kkossev is working on is not yet fully adapted for the new version.

In the mean time @amithalp has modified the driver of this post created by @kkossev to fit his needs for the new version of the device, we can find it here:

 * amithalp - Things to do - thermostatOperatingState - check what to present (ON/OFF or Idle/Heat) -DONE
 *              - invert relay option - parameter 7 on the thermostat menu allows to invert from NC to NO. Need to make the driver show the current value in the device page (NO or NC) and allow changing from the device page - DONE
 *              - Check how allow changing the setpoint temp using the dashboard tile with 0.5 C increment - DONE
 *              - Fix the driver so when you increase setpoint value from the thermostat itself it does not send the value 30 but the correct value - COULD NOT REPLICATE
 *              - Check why brighness become low after a few seconds even if you set it to high
 *              - invert relay option - what happens when doing factory reset and initializa - FACTORY RESET WIL CHANGE THE RELAY STATE TO NO. INITIALIZE WILL NOT CHANGE RELAY STATE

@amithalp I did some testing with the driver, nice, but unfortunately I can not use it as it is.

You did a nice thing when turning de device OFF, When OFF, the device room temp stays visible, I can see the benefits for that, did not know that was possible, but the issue with that is, all my other thermostats are the old version where this function is not available and I prefer some uniformity for al my thermostats.

I guess when stripping the driver, you stripped Force Manual Mode to. The plan was to use rule machine to set the mode always to Heat when changed to Auto, but you striped Auto from the mode too , so it is not possible to use RM to keep it on Heat.

I guess you striped Resend failed commands too?

Hi @BrunoVoeten , I have not looked at the code for a while and I will soon. In the mean time:

I am almost sure this is not my “fault”. I think this is this model’s functionality.

This is probably me

Not guilty (I think ) will check

BrunoVoeten · January 12, 2025, 12:39am

That was my first conclusion too, but when I load the new @kkossev driver the screen is complete dark when the device is OFF, or maybe it is a setting that comes with the driver?

This is what I see on your driver:

In @kkossev old an new driver is see:

Yes, It is indeed a new feature of the device but I think the reason of the issue is the frost protection, could it be you sent always an ON (frost protection) when save the preferences?
When I go in the device and set the frost protection to off, the display is full dark when turning off, when I save the preferences the frost protection becomes ON an the display is not full dark when turning OFF.

I was hoping adding Auto here the problem was solved (I see now Auto in Supported Thermostat Modes) but this was to good te be true LOL

The problem is when set the device by hand tot auto, in hubitat the auto is coming IN, after 2 seconds it is Heat again in the Hubitat device but the thermostats stays on Auto

Hi @BrunoVoeten ,
I started looking at my version for the driver as promised a couple of days ago but did not complete investigating and did not want to return with partial answers.
But, I could find out the thermostatMode issue - it seems like in this version there are only 2 modes available -"heat" and "off". It does make sense to me as this thermostat was meant for underfloor water heating systems. I am actually not sure what "auto" will be used for in this scenario.
The documentation i found shows: 'system_mode', tuya.valueConverterBasic.lookup({'heat': true, 'off': false})
I still do not have answers for the "device room temp stays visible" and the "Force manual mode" issues and I will try and figure it out soon

BrunoVoeten · January 18, 2025, 5:46pm

I am fairly certain that this is due to the frost protection. If I remove this piece of code, the frost protection remains off when saving the settings with the result the display is completely off when the thermostat is off.

@kkossev all my old thermostats

using the driver from this post are visible but inactief in Google home, I can not use them:

Is there is something changed between Hubitat - Google?

kkossev · January 21, 2025, 5:36am

I haven't used Google Home for quite a long time, but now I see a lot of errors (Debug logs in Google Home app are enabled).

Try testing with a Virtual Thermostat device using the stock driver, Does it work in your setup?

BrunoVoeten · January 21, 2025, 6:11am

There is no issue when I use a virtual thermostat:

kkossev · January 21, 2025, 6:28am

I reproduced the problem (using the BEOK thermostat and this driver), and hopefully, I can find the reason for the incompatibility.

BrunoVoeten · January 21, 2025, 8:12am

I believe in you😄
