Z-Wave thermostat #103

Closed emiliosic closed 8 years ago

emiliosic commented 8 years ago

How can I set on ha-bridge a z-wave thermostat through a Vera? Right now I have something working via Vera scenes (as in Turn on heat, turn off heat), but if I say, "Set thermostat to 65", and the thermostat is configured as a dimmer, it sends a command to Vera but doesn't change the temp. Any suggestions?

If the thermostat is a device that can be dimmed, you will need to use the intensity percent dim control when using the helper for generating a bridge device. Otherwise it may be a specific call that you will need to look up in the Vera API. The best place to get this answered would be on the micassverde forum.

For reference, it works. Took a look at the LUUP API here: http://wiki.micasaverde.com/index.php/Luup_UPnP_Variables_and_Actions

The 'Dim URL' for a device named 'Thermostat' is this: http://[VERA IP]:3480/data_request?id=action&output_format=json&DeviceNum=[Vera Device ID]&serviceId=urn:upnp-org:serviceId:TemperatureSetpoint1&action=SetCurrentSetpoint&NewCurrentSetpoint=${intensity.percent}

The Alexa utterance (the command spoken to Alexa is): "set thermostat to XX" (as in 70 for 70 degrees).

Note that the C/F setting is set on Vera. Alexa converts the value requested (70) to the 70% of 255. In other words, converts a 'percentage' between 0..100 to a byte 0..255. ha-bridge converts the '175' back to '70' that Vera expects. Vera also has commands to set the mode heat/cool/auto, but I'm leaving those as-is for now.

Great! Glad it is working.
