Setting wake-up interval on Horstmann C-Stat 11-ZW

[JohnAdders]

I can't seem to work out how to get the wake up interval on a Horstmann C-Stat 11-ZW thermostat to stick. If I use either the device setup page in domoticz or the control panel and set the wake up time then send a NIF on the device the logs shows the message getting sent with a value of 600 but the device still doesn't wake up and report in after 10 minutes.

Does anyone have one of these and can tell me what I'm doing wrong?

Thanks

Answering my own post and I've been playing around with these now for while and finally got things working better.

The trick seems to be exiting the zwave part of the domoticz interface after each command. There seems to be an odd issue that if you include the device and then try and play with values the controller gets dropped out of group 1 of the thermostat and then won't respond to certain commands including setting the wake up.

So what you have to do is

1) include the node
2) go back to hardware and back into zwave setup
3) select the thermostat and you can now change the wake up and temperature change delta
4) Press send NIF several on the thermostat several times so that the command gets picked up
5) go back to hardware and back in to confirm that the setting has change
6) Add the switch you want to control to group 2
7) Press send NIF several on the thermostat several times so that the command gets picked up
8) go back to hardware and back in to confirm that the groups are updated

Once this has been done the temperature meter in domoitcz seems to work well and while you can control the set point from domoticz it seems to time out after a few hours and any schedule changes or user overrides are not picked up.

I'm currently investigating extending open-zwave to get schedule support and then we'll see about integrating that into domoticz

I also have a Horstmann Thermostat, though a different model. Your experience with scheduled changes to thermostat SP mirror mine. From the Domoticz perspective, the schedule gets executed, the command gets set, and there is no reported timeout or error. Despite that however, the SP doesn't change and Domoticzs displays the old SP.

If the SP is changed manually on the thermostat, Domiticz displays the changed SP immediately; so the thermostat is sending stuff back.
