Setpoint Item Type

[snizzleorg]

There is a temperature Item typ but does a Setpoint Temperature Item exists?

This should be a thermostat item. So you need the current temperature and the target temperature. (See https://github.com/redhell/homebridge-openHAB/blob/master/items/ThermostatItem.js ,does not work at the moment). @tommasomarchionni It would be cool to know if you can combine multiple items from openhab to one.

THERMOSTAT_MODE (since 1.6.0) Used to get and set the mode (of Number type) of the thermostat numeric values translate to the following types

0 = "Off"
1 = "Heat"
2 = "Cool"
3 = "Auto"
4 = "Aux Heat"
5 = "Resume"
6 = "Fan Only"
7 = "Furnace"
8 = "Dry Air"
9 = "Moist Air"
10 = "Auto Changeover"
11 = "Heat Econ"
12 = "Cool Econ"
13 = "Away"

THERMOSTAT_OPERATING_STATE (since 1.6.0) Used to get the operating state (of Number type) of the thermostat numeric values translate to the following types

0 = "Idle"
1 = "Heating"
2 = "Cooling"
3 = "Fan Only"
4 = "Pending Heat"
5 = "Pending Cool"
6 = "Vent / Economizer"

THERMOSTAT_SETPOINT (since 1.6.0) Used to get and set the setpoint of the thermostat setpoint_type=value : parameter to select setpoint type, value is one of the following numerical values:

1 = Heat 
2 = Cool 
*setpoint_scale=value** : parameter to select setpoint scale, value is one of the following numerical values:
0 = Celsius 
1 = Fahrenheit 

THERMOSTAT_FAN_MODE (since 1.6.0) Used to get the fan mode (of Number type) of the thermostat numeric values translate to the following types

0 = "Auto Low"
1 = "On Low"
2 = "Auto High"
3 = "On High"
4 = "Unknown"
5 = "Unknown"
6 = "Circulate"

THERMOSTAT_FAN_STATE (since 1.6.0) Used to get the fan state (of Number type) of the thermostat numeric values translate to the following types

0 = "Idle"
1 = "Running"
2 = "Running High"

Those are the properties of the thermostat item in openhab. But anyways homkitbridge reads the sitemap so there one way of doing this could be combining a Text item (the current temperature) and a Setpoint Item (the target temperature) in a group or frame.

But the combination i believe would need to be done by the home bridge-openHAB plugin

The easiest way of going about this I think however would be using the target temperature as the current temperature...

now that i have thermostats i wonder if providing support for them is on the roadmap.. or what is required to get things working.

[snizzleorg]

I saw that @redhell added a ThermostatItem. So I guess this should now be supported somehow.

[redhell]

Actually this does not work at the moment. There are more things to get a working thermostat.

I think you need multiple inputs like current temperature and the whished temperature. In my situation these are two items and i have to figure out how to combine them.

[snizzleorg]

In my situation as well... But couldn't you just use the set point for both? Then the Thermostat would always have reached the set point but I think this is not a big issue

What is a general thermostat? In my case, my room thermostat (MAX! - controlled by the Openhab MAX!Cube-Binding) is controlling four further radiator thermostats. It has not a simple heating state, it is rather setting the valve position of each radiator separately and adaptively. However the most important things would be the actual temperature (read-only) and the set temperature (read/write). Currently, in the exported sitemap, the Setpoint element is used for the set temperature and a Text element is used for the actual temperature. Nevertheless, both the Text and the Setpoint element are interpreted by homebridge as read-only, the Setpoint element, however, should be also writable. Wouldn't that be sufficient for setting the room temperature?

@gstiegl i would be pleased to try

[tommasomarchionni]

Now with homebridge-openhab@0.1.30 thermostat is in experimental. Now you can only see current temperature and set target temperature.

gonna check .. thanks! :hotsprings:

[gstiegl]

Great! I will check this asap as well! Thanks!

Hm, seems not to work im my case. I am using the following configuration:

"platforms": [ { "platform": "openHAB", "name": "openHAB", "host": "localhost", "port": "8080", "sitemap": "homekit", "useLabelForName": true, "customAttrs": [ { "itemName":"LivingWallThermostatActualTemp", "itemLabel":"Thermostat", "itemType": "ThermostatItem", "itemSubType":"CurrentTemperatureCItem", "itemUniqueAggregationId":1 }, { "itemName":"LivingWallThermostatSetTemp", "itemLabel":"Thermostat", "itemType": "ThermostatItem", "itemSubType":"TargetTemperatureCItem", "itemUniqueAggregationId":1 } ] } ]

and homekit.sitemap on the openhab side looks as follows:

Setpoint item=LivingWallThermostatSetTemp label="Regeltemperatur" Text item=LivingWallThermostatActualTemp label="Temperatur"

which leads to the following message in my homebridge log:

[openHAB] Platform - The widget 'Thermostat' of type NumberItem is an item not handled. [openHAB] Platform - The widget 'Thermostat' of type NumberItem is an item not handled.

Is there anything else to do?
