Everspring ST814 temperature and humidity

[sc...@5petersons.com]

I am trying to add an Everspring ST814 temperature and humidity control to my z-wave network in openHAB.

I have a node id associated with the device but cannot seem to get any information from the device.  In HABAdmin it is showing the device manufacturer and description properly in the devices tab so I think it is setup correctly but not really sure.

No xml file for the node exists in the etc\zwave\1.4\ folder, is this an issue?

The documentation talks about associating devices to group 1 and group 2 of the ST814 but I cannot seem to get any devices added to the groups and the documentation seems lacking.  Does anyone have any idea how this is done?

Here is my items config:

Number sBathroomKidsTemp "Kids Bathroom Temp" {zwave="8:command=sensor_multilevel,sensor_type=1"}

Number sBathroomKidsHumidity "Kids Bathroom Humidity" {zwave="8:command=sensor_multilevel,sensor_type=5"}

Number sBathroomKidsBattery "Kids Bathroom Battery" {zwave="8:command=battery"}

I have also uploaded my log files.

Thanks,

Scott

I’ve got a bunch of these, but have not tried to use them on openHAB. However, the fact that there’s no XML file means that the device has not completed its initialisation. As this is a battery device, it only wakes up ‘occasionally’ - I think by default it might be 10 minutes. You can wake it up manually by pressing the button on the back 3 times.

Are there any errors in the log? Your item configs are also incorrect - you should use the name instead of the number for the sensor type (e.g. command=SENSOR_MULTILEVEL, sensorType=TEMPERATURE). I’ve been meaning to change the wiki to make this clearer, but haven’t gotten around to it.

Cheers

Chris

ok, I think I figured out the problem.  I am using some older z-wave products and my Intermatic HA07 remote does not support adding associations to a device.  I have been trying to figure out how to get around this to no avail.

Does anyone have a suggestion for a low cost handheld remote that supports adding associations or some software I can use to add associations?

Thanks,

Scott

HABmin will allow you to set associations (https://github.com/cdjackson/HABmin). Alternatively OZWCP, but I’ve never managed to get this working.

Thanks Chris, does my USB stick attached to the computer need to be the primary device before I can set an association with HABmin?

I have tried using HABmin but is does not keep change to the association.

Good question - I don’t think it needs to be the primary controller, but I’m not 100% sure but I think any controller can set an association in zwave.

However, the thing to remember with battery devices is that it will take at least 1 wakeup period to actually set the associations. HABmin (currently) doesn’t retain the value while this is happening, so it does indicate incorrectly…. Let me try and explain….  In HABmin, you set a node as a “member” of a group. HABmin then sends the command to the zwave stick - for a battery device, this actually goes into a queue in the binding until the node sends a wakeup. When the wakeup is received, HABmin will send the command to set the association… However, while this is happening, the GUI will set the value back to it’s original value, which probably says non member. Note also that if you restart the binding during this process, the queued messages will be lost so you’ll need to start again.

For the ST814, you should be able to set the association in HABmin, press the button on the back 3 times, and this should wake the device up and cause the association to be set. Then, you should select “Association Groups” in HABmin and click the Refresh button in to refresh the associations, and press the button 3 times again - this should (hopefully!) now show that the association is set…….. 

Battery devices in zwave aren’t simple or obvious….  Your other option, especially with the ‘healing’ binding from the HABmin github repo is to set the association and come back in 24 hours and hopefully it will be ok :) However, you’re probably like me and want to know that it’s set correctly, in which case the above should work - I’ve done exactly this on the SP814 which should be the same as the ST814…

Chris, thank you for your time!  Great explanation and your steps in paragraph 3 worked perfectly.

I did not have to make my USB device the master.

Great - I’m glad it’s up and running :)
