As a supplementary question, now I have a Heat / Off switch.

Can I make this actually switch my boiler control on? This would neatly solve an issue I've been considering with TRVs.

Currently altering it from 'Off' to 'Heat' does nothing and does not appear to alter the value of the ModeTarget variable which is reflected in the logs.

I also need to chase something down I suspect in HA Bridge as I've managed to re-create another CurrentSetpoint

Looking at the manual and the supported command classes you posted, no, unfortunately the heater does not support mode changing. It is only reporting 3 command classes:

1. Current temperature (49)
2. Temperature Setpoint (67)
3. Battery Level (128)

So to turn the heat on, you need to change the setpoint to be above the current temperature.

Interesting, thanks!

Do you have the relay ASR-ZW?

[CatmanV2]

@powisquare I do, sir but with OpenLuup have found no way to control it directly.

It's associated directly with the SRT-321 so that bit works fine.

Unfortunately my one is still paired to vera so I am not sure how to look up the command classes but I do note in Altui under Commands there is
heater_off,heater_heat. Would that be any good?

Edit.. also there is a SwitchPower1 SetTarget

Yes, that I can control, but it doesn't do anything.

What I think is the problem is that Z-way thinks (probably cos I told it) that the ASR is in fact:
Secure Controls SRT 323 Thermostat

Command classes are:
Basic • SwitchBinary • ThermostatMode • CRC16 • ManufacturerSpecific • Version •

But the switch action in Z-way also does nothing.

Any idea how to get the right device in Z-way?

<edit>. Ooooh poking around in Z-way I can turn it on and off manually with the Thermostat mode 'expert' command

@catmanv2 switch binary should allow you to turn it on/off. Maybe a raw Zwave command will do it.

@therealdb Ooooh poking around in Z-way I can turn it on and off manually with the Thermostat mode 'expert' command.

That doesn't appear in AltUI as a variable and has no 'direct' control in Z-Way

Z-Way is using the D_BinaryLight1.xml and .json file which I guess accounts for that.

Is there a 'right' file?

@catmanv2

Let's take this in steps:

1. Which of the two commands is actually responding? The binary switch? or the Thermostat mode?
2. How would like the device to look like on the UI? A heater device or a light switch?

The easy path is to use the device corresponding to the command class so we don't have to do any custom actions. This is one odd device which I am sure the z-way bridge didn't know what to do with but all the command classes are supported so it is a matter of linking the device file with the right actions.

The thermostat mode command class will be actuated by the Heater device. The binary switch will be actuated by the light switch.

[CatmanV2]

1. Thermostat mode
2. Heater device

Then change the device files like you did for the thermostat. I think it should work. The temperature read back and the set point just won't work... having fun yet?

The technical part: The command class is 64 and is a regular command class thermostat. The z-way bridge is just not set to recognize this type of devices though it is implementing the variables and command class correctly.

[powisquare]

Could change it to a boiler actuator perhaps ...

I'm having a blast :). Probably boring the pants off you though!

Changed the files to the same ones as the stat, but no control of the Thermostat Mode either with the arrows or in the variables...

None of them appear in the drop down of Zway. Feels like it's identifying itself as part of the pair

[rafale77]

Maybe try the more generic D_Heater1.json. Sorry I don't have these devices and don't even have a heater so I am just guessing as to what device file corresponds best.

[CatmanV2]

@rafale77
Nailed it! TRVs here I come!

[powisquare]

I have one of these thermostats on Vera 3 and another on vera plus. For some reason they have different device_json and behave bit differently. Anything I can do to get them both on D_Heater1.json which suits me better than D_HeaterTempNoOnOff1.json as I don't need cooling? Have tried just replacing the text in Attributes but doesn't seem to save.

[rafale77]

If you are doing this through the verabridge and reload luup, indeed it will go back to the same file being used by the vera. You need to change this field on the vera then luup reload both the vera and openLuup.

[powisquare]

Thank you - whereabouts in vera may I do this? Tried in device Params but doesn't seem to save. Do see 'Change property command sent' but after reload it reverts back.
