Changelog:

v2.1.1 (BETA)

  • Add support for the Z-Water regulator
  • Update to meshdriver v1.2.30
  • Note : due to an S2 issue within the Homey Z-wave core, the measured temperatures are not reported for the Z-wave thermostat (FW 1.92) and Z-TRM2(fx) thermostats as well as the Z-Water regulator. When this will be resolved, it is likely that the thermostat will need to be re-included

v2.1.0 (BETA)

  • Add support for the Z-wave thermostat (FW 1.92)
  • Add support for the Z-TRM2(fx) thermostat
  • Add all remaining settings for the thermostats
  • Add Power Regulator Mode action card for the Z-wave thermostat (use at own risk)

Note: due to an issue within the Homey Z-wave core, the measured temperatures are not reported for the Z-wave thermostat (FW 1.92) and the Z-TRM2(fx) thermostats. When this will be resolved, it is likely that the thermostat will need to be re-included

v2.0.2

  • Add support for the Z-Push button 2 and Z-Push button 8 devices
  • Minor (cosmetical) modifications to make the app Homey SW v2.0.0 compatible

v2.0.1

  • Add thermostat onoff state trigger- and condition cards

v2.0.0

  • SDK2 rewrite of the ThermoFloor / Heatit app
  • SDK2 rewrite of the Multireg / Heatit Z-Wave thermostat device driver

Frequently Asked Questions:

How do I add other devices to the association groups of the Heat-it Z-push button devices

According to the manual:

Set association by operating primary controller/gateway to send association command to the remote control:
When set association from primary controller/gateway, the remote control shall be activated first, if it is not activated, you should activate it manually.
The primary controller/gateway sends association command to the remote control using ā€œCommand Class ASSOCIATIONā€ or ā€œCommand Class Multi Channel Associationā€

It all comes down to timing of the actionsā€¦ Since the device will only be awake (able to receive new settings) for 5 seconds.
Otherwise the changed settings should be communicated with the next wake-up, which could take up to 28800 seconds (wake-up interval).

Follow the next steps to create a direct association between Z-push button and another device in Homeyā€™s network:
in Z-wave developer tools:

  1. Open the Z-wave developer tools at: https://developer.athom.com/tools/zwave
  2. Enable logging and filter on Node[151]: Marked as o where 151 is the node ID of the Z-push button device
  3. Press and hold the ā€˜Iā€™ and ā€˜Oā€™ of group 2 (upper rockers) for 3 seconds; you now should see a ā€˜Node[151]: Marked as onlineā€™ log followed by a ā€˜Node[151]: Marked as offlineā€™ log 5 seconds later
  4. Look-up the Node ID of to be associated device, visible in the Nodes overview on the same page, in this example 221 (a Fibaro Dimmer-2)

in the Homey app:

  1. Open the device settings of the Z-push button device, go to Advanced settings
  2. In the Advanced settings, go to the associations section and check which button group you want to add the Fibaro Dimmer-2 to. Upper rockers = Group 2
  3. Add the node ID of the Fibaro Dimmer-2 (221) to the the desired group, in this example add 221 to Group 2

    IMG_2028.jpg750Ɨ534 118 KB
  4. press ā€˜< Advanced settingsā€™ to go back to the Advanced settings
    IMG_2029
    IMG_2029.jpg750Ɨ784 55.9 KB
  5. Here comes the tricky part; keep an eye on the filtered Z-wave log and press and hold the ā€˜Iā€™ and ā€˜Oā€™ of group 2 (upper rockers) for 3 seconds to wake-up the Z-push button.
  6. Once you see the ā€˜Node[151]: Marked as onlineā€™ in the Z-wave log of the developers tools, press the check mark at the top right side of the Advanced settings to save the settings to the device
  7. if the timing is right, you should see the green banner: ā€˜Settings were savedā€™
    IMG_2032
    IMG_2032.jpg750Ɨ562 71.3 KB

    And you should be able to control the dimmer-2 from the Z-push button device

in Z-wave developer tools:

  1. in the (unfiltered) Z-wave log, you can verify that the command was send successfully:
    ā€˜Node[151]: sendData to COMMAND_CLASS_MULTI_CHANNEL_ASSOCIATION, params 0x0102ddā€™
    Here: the ā€˜paramsā€™ can be devided into: 01 = SET, 02 = Group 2, dd = 0xdd = 221

Hi!

First of all, great app @TedTolboom ! Works perfectly.
Just wondering if there will be support for the Z-therm2 any time soon? I have purchased 5 units (have 1 unit of the first generation) that I am not able to connect to Homey :-/
I will be happy to contribute to your PayPal!

#5

@Dais Thanks!
The ThermoFloor / Heat-it app is my last SDK1 app.
Before extending it with new products, I will need to convert it to SDK2; it doesnā€™t make sense to define new drivers on a SDK version that is no longer supported.

Thermostats are one of the more difficult drivers to setup, because it involves quite some device specific logic that needs to be embedded into the driverā€¦

I just finished creating a SDK2 version of a Z-wave thermostat for the Remotec ZXT-120 and ZXT-600, which I created with the ThermoFloor / Heat-it thermostat in mind. It should be possible to re-use 95% of the code for these devices.

So first I will need to re-write the existing app to SDK2 version, before I will be able to extend the support for additional devices. Coarse timeline I have in mind is to finish the SDK2 re-write in September and add support for the remaining devices (Z-therm / Z-scene controller) in October (before the winter starts)ā€¦

Dear @ TedTolboom,

I just bought TRM2 and tried to pair with Homey but no luck. I think Iā€™m doing something wrong. Can you please help me with the advice?

#7

Hi @Yermek,
You are not doing something wrong. The TRM2 is currently not supported yet by this app.
See my previous comment on expected timeline.

#8

Hi @TedTolboom October sounds very soon! Thanks a lot. I will donate to support your work.

#9

Also eagerly waiting for the Heatit Z-scene controller support! Happy to donate to support your work for it. With limited technical expertise, I doubt I have anything to contribute with, but let me know if there are anything you need @TedTolboom to speed up the process :slight_smile:

#10

Thermofloor/HeatIt have several new devices in their portfolio now: Z-trm2, Z-Relay, Z-Water, Z-Din616 and Z-Scene Controller. All these devices are, to my knowledge, available now.

#11

Several devices have been added to their portfolio, but not all are already available.
The Z-TRM2 is delayed due to a certification issue, as communicated last week.
https://www.heatit.com/heating-control/floor-heating-thermostats/heatit-z-trm2/

Any support / contribution is much appreciatedā€¦

As indicated before, I will first need to convert the existing app to SDK2 basis, verify that it is working correctly before being able to extend the support for additional devices.

In order to add support for the other devices, I will need to get access to these devices myself for local debugging. Remote debugging (without VPN connections and direct sight to the device) is not possible.
Thermostats but also the multi-relay devices, typically have their own unique way of control logic, that I will need to embed in the device driver.

I will get in contact with ThermoFloor (development) to see if they can support this app development with providing access to these devices.

#12

Yes Ted, it came to my attention that Thermofloor had withdrawn the Z-Trm2 recently. To my knowledge this is due to some S2 issues which preventes devices from being added in n secure-mode. This is not only a problem with ZTrm2 but with Z-Water as well.

#13

I have recently ordered 2 pieces of heatit trm2, will there be any issue with thoose and future update with support of app? Seems to be firmwire related with trm2, and nothing easy to do my self.

#14

@Sejkooz I donā€™t know the background of the issue that is blocking certification of the Z-trm2.

I know that the Z-wave alliance recently raised the requirements regarding security measures regarding certification. Which could be the reason, but this is speculating.

Due to the (multi-version) Z-wave implementation of Homey, I think it will have a real impact and both versions will be compatible with the Homey (app).

#15

A brief update on adding the additional devices.

Iā€™m in close contact with ThermoFloor to setup a collaboration to support these device implementations.
But this will be depending on the device certification by the Z-wave alliance.

So weā€™ll have to wait until the devices are certified, unfortunately.

In the meantime, Iā€™m rewriting the current app to SDK2 base.

#16

Do you think this issue will be solved by the end october? Winter is coming :slight_smile:

#17

@Yermek I canā€™t comment on timelines of ThermoFloor or involved third parties (Z-wave alliance).

Even if the devices and certified firmware would be available now, it would be quite some work to add support for these devicesā€¦ so likely end of October will not be feasible.

Once I have more information, I will share it in this topic.

#18

@ TedTolboom got it! will wait.

#19

Luckily enough the Z-TRM2 can be controlled by itself :wink:
Wouldnā€™t want to have community members freezingā€¦

#20

I am ready to order a trm2.

I could have it send to you, im still building my bathroom so i can miss it for another month.
Is that an option? :smile:

I rather have it implemented and working, than on manual and when my bathroom is done it isnt implemented :slight_smile:
