Howto use StellaZ in Domoticz? SetPoints...

[zofiel]

In case you missed my post in the Heating/Cooling forum -

Finally managed to include my new StellaZ valve. Eventually found an on-line quick-start guide that said to push/hold the button down for at least 10 secs, with the controller in include mode. http://www.vesternet.com/downloads/dl/f ... manual.pdf ...

Can't get it out of Comfort mode. However, I can set the comfort mode value using timers.

It also responds to a simple On/Off, so I can control it from the room thermostat.

However, I had to set the wake-up interval down to 300 to get it to respond.

I followed the same guide, but after 5 secs pressing the button, the light change to red around 2 secs, then It's blinking green again

I just ignored the light, and held the button down for 15 secs.
Worked for me, the device was included.

In beta #5110 it is now possible to set the thermostat mode
Of course, the thermostat will only adopt the new settings, when the wakeup interval is reached....

Is it necessary to include the Stellaz again for this?

As a late followup to my post above, I solved all those issues ... the reason the JSON commands were not working was due to the fact I needed to add username and password. After doing that the virtual switch was working fine.

Now when you update to the new version of domoticz a new Thermostat Mode device appears for each StellaZ valve. Cool but ...
There are at least two problems
a) in order to change mode you can't just click on the control. you have to use the Edit button and when you select a new mode and click OK, the interface still shows the old mode until the valve actually synchronizes (or you force it by pressing its physical button)
b) I tried to set up a virtual selector switch to use in the dashboard for quickly changing mode but it is unclear what to use as nvalue and svalue to change mode. It seems nvalue=1 set the Comfort mode and nvalue=0 set the Frost Protection mode (svalue seems to be irrelevant). The values for Energy Saving and Direct modes should be 11 and 31, but these do not work.
Has anyone any idea on how to set those modes with JSON?

My observations
JSON
/json.htm?type=command&param=udevice&idx=...&nvalue=1 - comfort
/json.htm?type=command&param=udevice&idx=...&nvalue=0 - frost

everything else is not working

upd
/json.htm?type=command&param=udevice&idx=...&nvalue=2 - Energy Saving
/json.htm?type=command&param=udevice&idx=...&nvalue=3 - Direct Valve Control

All working

[Sevift]

But a glitch in OpenZWave Control Panel
When you switch to "Direct Valve Control" (nvalue=3), OpenZWave Control Panel will display the mode that you have chosen before.

But this does not affect the work.
You need to create a virtual device.
/json.htm?type=command&param=udevice&idx=...&nvalue=0
/json.htm?type=command&param=udevice&idx=...&nvalue=1
/json.htm?type=command&param=udevice&idx=...&nvalue=2
/json.htm?type=command&param=udevice&idx=...&nvalue=3
The device Domoticz Thermostat Mode is not working properly

I checked the work in the "Direct Control Valve" mode. Everything works fine.

Code: Select all

local tempNeed  = tonumber(otherdevices_svalues[thermostatVName]) 
local tempHum = tonumber(otherdevices_temperature[tempHumName])

setLevel = (tempNeed - tempHum) * 100

	if setLevel < 0 then
		setLevel = 0
	end
	
	if setLevel > 100 then
		setLevel = 100
	end	
commandArray[#commandArray+1] = {[thermostatName] = 'Set Level ' ..setLevel}

Hi Everybody,

I successfully added my two new StellaZ thermostats. I did read al the tips and suggestions in this thread, but I'm not able to figure it out. I just don't understand how to use the Json links and which Idx I have to use (every StellaZ has 5 idx's?).

I really would like to use direct valve control. I understand I have to switch to nvalue 3, but I have no Idea how to do this exactly. Hope someone can give me some hints in the right direction. Thanks!

[cocojumbo]

I too wonder about this. I can set all three modes except Direct Valve Control

[jannl]

Not sure if you explicitly need to set it. When set the valve to on it opens...

[Sevift]

You're right. It is possible and in a standard way. But the bug is present.

Comfort mode

Excellent work - level adjusts automatically.


Direct Valve Control mode

Work, level supports manually, but does not change the operation mode visually. However, the thermostat is working properly

[Blueone]

I experiencing the same thing, the modes "frost protection", comfort and "energy saving" are working fine, only "Direct valve control" isn't displaying properly but is working untill the batteries are changed, after that you have to set it to "Direct valve control again" as is goes back to Comfort as that is what the controller thinks.

[frunns]

Cool that direct valve control at least works, even though it doesn't look like it.

Anyone had any issues with the temperature on their StellaZ? I'm getting consistently 0, and even the thermostat itself seems to believe that 0 is correct as it's right now ~6 degrees warmer in that room than it should be.
