Z-Uno: Trying to send Multi-level sensor report to Eurotronic Spirit TRV

Post by morgano1 » 31 Dec 2018 03:05

I have just started with Z-Uno, although I have been using Z-wave for some time.

I am trying to achieve quite a simple task, but I am having trouble, and I suspect that it may not be possible at the moment with the Z-Uno.

I would like to connect a temperature sensor to the Z-Uno (e.g. DS18B20) and send the temperature reports from this to a Eurotronic Spirit TRV i.e. use the Z-Uno as an external temperature provider for the Spirit.

The Spirit can be configured to accept multi-level sensor reports by Association (rather than using its own internal sensor), although these cannot be 'endpoint encapsulated'.

As far as I can see in the docs, there doesn't appear to be a method for sending multilevel sensor messages by Association (only on/off, or dimmer commands).

Can anyone confirm this?

Also, if this is not available as a 'high-level' option, is it possible to send raw data to an address? I know the sequence of bytes that I need to send in the message, but there does not appear to be a 'raw data send' type of command either.

Any comments/observations/guidance would be greatly appreciated!

You need to set up simple Association (group #1) to Eurotronic. This will produce simple (non-channaled) reports.

Looking at the Reference guide - there doesn't appear to be any way to send Temperature readings (Multi-level sensor) using an Association group. If I am misunderstanding something please could you elaborate?

Code: Select all

 ZUNO_SETUP_ASSOCIATIONS(ControlGroupType_1, ControlGroupType_2,...) ControlGroupType_n Type of group defines which commands will be sent to distant devices in the network. There is only three possible types available:

    ZUNO_ASSOCIATION_GROUP_SET_VALUE — send switch on/off commands (using Basic Command Class) to devices in Z-Wave network by calling zunoSendToGroupSetValueCommand()
    ZUNO_ASSOCIATION_GROUP_SET_VALUE_AND_DIM — send dimming commands (using Switch Multilevel Command Class) to devices in Z-Wave network by calling zunoSendToGroupDimmingCommand(). You can also use zunoSendToGroupSetValueCommand() for devices in this group to send switch on/off commands (using Basic Command Class).
    ZUNO_ASSOCIATION_GROUP_SCENE_CONTROL — send scene activation commands (using Scene Activation Command Class) to devices in Z-Wave network by calling zunoSendToGroupScene()
    ZUNO_ASSOCIATION_GROUP_DOORLOCK — send door lock open/close commands (using Door Lock Command Class) to devices in Z-Wave network by calling zunoSendToGroupDoorlockControl()

I think PoltoS is trying to say this: A Z-Uno always has a group 1 - you do not need to add or change any code. So on your controller, please navigate to the Z-Uno and find the button or menu to change associations. Then add the Spirit as a "single channel association" (not "multi") to group 1 and the Z-Uno will automatically only send non-encapsulated reports. I cannot be more specific because each gateway has different menu's and screens to do that.

I find this solution a bit dangerous because associating the Spirit to Z-Uno group 1 will not only send the Multilevel_Sensor_Report to it, but also all other defined channels in your Z-uno sketch.
Please note that the Spirit supports Basic CC as follows:
0x00 Energy Save Heating
0x0F OFF No Heating. Only Frost-protection
0xF0 Full Power Heating
0xFE Manufacturer Specific
0xFF Heating Switches into comfort heating mode.

So in case your Z-uno has one Basic channel defined for other purposes (let's say to control a light or a dimmer), you might expect strange behaviors on the Spirit thermostat.

Best to have dedicated group that sends Multi-Level Sensor reports, which unfortunately not available in 2.1.4. Let's hope that this gets introduced in 2.1.5.

The thermostat is supposed to ignore the Basic Report. So it is safe.

There would be no reports group bin 2.1.5.

But as a last resort you can send any packet from Z-Uno.

Right, I've confused between BASIC_SET and BASIC_REPORT.
Thanks
