Heatit Z-wave thermostat

[rbisschops]

Ok i found it.
Although the XML says you need 11 i tested it with 3 and then it went to ECO mode.
2 is still cooling but i do not have that option in the thermostat.

So now i use a selector switch with the buttons Off, On and Eco instead of the stupid Thermostat mode button which only shows which mode it is.

Hi all,

As the temperatures are getting lower I fired up my Heatit Z-wave thermostat. Obviously I want to control it with Domoticz. So after reading this thread I found that it's not a walk in the park.
I can confirm ECO mode is "3" and not "11" in my Zwave plus version.

So I tried changing the XML to "3"and also changing the text to "ECO" instead of "Energy heat". However I don't see it back in Domoticz or the Z-Wave settings. I did reboot the complete RPi. What i'm I doing wrong here?

I did not change the XML if I can recall. I use json command at a switch selector.
Let me know if I need to tell you how I did it.
It works fine for me

Thx @tlpeter. Csn you share with ushow you made it work. I have a bit of a feeling how to do it, but like to your solution.

Thx

Here you go.

I used a virtual selectorswitch and i have 0, 10 and 20 as level.
The actions are:

0 http://127.0.0.1:8080/json.htm?type=com ... 8&nvalue=0
10 http://127.0.0.1:8080/json.htm?type=com ... 8&nvalue=1
20 http://127.0.0.1:8080/json.htm?type=com ... 8&nvalue=3

2288 is the idx of my thermostate so you have to look that up for yours.

There are also two setpoints where one is called ( i think) energy heat which is the "eco" setting and the other one is the heat which i use to turn on the thermostat for heating the floor.
The eco could be used as a level for a minimum temp of the floor.
I did not make it smart with scripts but i turn it on manually and if i forget then a script turns it off an hour before bedtime.

Thinking of getting a Heatit thermostat, today i have a Ebeco thermostat to control the floor temperature, do i need to replace the temp sensor in the floor to get Heatit thermostat to work, or can i use the old one for the Ebeco?

[Skjalg]

No problem, replaced some ebeco regulators myself with heatit and used the old floor sensor from ebeco. Everything works fine except I can't get the readings from the floor sensor in domoticz. I can see the value in open Zwave control panel but no devices has been created in domoticz.

Hi, did you solve the problem with the floor sensor temp not showing up in Domoticz? I have the same problem with a Heatit Z-TRM2fx. It is working fine but there is no device added for the floor temp.

Hello all,

I have included a Z-TRM3 (ThermoFloor AS Heatit Thermostat TF 058) to my Z-wave network. Image: https://ibb.co/B6PV1G8

The device is working from the Open-Zwave control panel. The parameter "Heating mode setpoint" as shown in the image above set to 195 (19,5 *C) can be used to control the thermostat.

But in Domoticz. there is no corresponding device to this parameter. So I cannot use Domoticz to script the thermostat. Image: https://ibb.co/ZL55KRh

The device Heating Setpoint is not working.

How can I fix this? Do I need to create a custom device and how do I need to do this?

I found this heatit058.xml and created a line in manufacturer_specific.xml:

The correct device ID (0203) and type (3) is chosen: image: https://ibb.co/5v1M37H

What can I do to fix this? It feels like I'm close.

[stephanvdplas]

I see there is a better heatit058.xml: https://github.com/OpenZWave/open-zwave ... 656fbfb955

I'll try re-include the device using this tonight and let you know the outcome.

[madpatrick]

I'm using this version

Which firmware do you have ?

Alas... one step further, but not yet there.


This parameter 9 (Heating setpoint) now works. I can read and set the setpoint and it actually sets it on the thermostat.

The devices that are created are shown here:

There is one setpoint, but it does not reflect the current setting. It also doesn't work setting the thermostat.

How can I create a device for the parameter 9 value?

Your device 2042 should work and change the setpoint.
Have you checked your firmware?

There is a known issue with setting the setpoint with the default firmware
Try to set your setpoint to > 26,5 C.
If this is working then the problem is with firmware.

Hi Patrick,

Thanks for your reply!

I think your version is the same as mine:

[madpatrick]

Can you try to set the setpoint to 27 and check what is happening

My firmware is 4.2
If yours is 4.0 you need to flash your firmware
See download link on the page i gave you

You are right, setting the setpoint to .5 values > 26* does work.
I'll try to upgrade the firmware and give feedback when I'm done.

I'm following the OTA upgrade manual but I am stuck at the part that says: Select the thermostat general V2 and press Get.

The Get button is greyed out and I cannot browse to the otz file either:



The Domoticz service has been stopped. And I also stopped and started the COM3 device.

[madpatrick]

I've tried with my backup stick.
In the first few attempt id also didn't get an connection with the device.
After a few time some how when (connect and disconnect USB and restart PC controller) i pushed the get button is saw in the footer some action the boxes were filled with infomrat and i could select the file.

SOmetime it helps to have de device very close to the stick

[madpatrick]

I tried it again and nothing happend
When i click on "Properties1" and then push GET it worked

Don't forget to push first on the "Wheel" and "Detect"

I fixed it. After excluding the device and re-including it (now via this PC controller app) it was able to update. I updated the firmware and it works as a charm now.
@madpatrick thanks for your support!
