Hi! :waving_hand:

I have an Openhab 5.0.2 setup connected to a Velbus installation with a vmbel1 module which I want to use as a thermostat. I want to make it configureable in Google Home too. I followed the instructions here (Google Assistant | openHAB) which worked partially. I can now see my thermostat, but I can’t change anything. The set temperature is immutable in Google Home and the modes aren’t being mapping correctly.

As described in the docs, i created a group with 3 members:

  • Bathroom_Thermostat_currentTemp
  • Bathroom_thermostat_mode
  • Bathroom_currentTemp_setpoint

The mode item has the following GA metadata config:

value: thermostatMode
config:
supportedModes:
- Day
- Night
- Comfort
- Safe

The group GA metadata looks like this:

value: Thermostat
config:
  thermostatTemperatureRange: 0,40
  modes: off=SAFE,heat=DAY,eco=NIGHT,on=DAY
  roomHint: Bathroom

Whatever mode I choose in Openhab (Safe, Day, Night or Day) doesn’t show up in Google and just shows as “On”.
Whatever mode I choose in Google defaults to the “Safe” mode in Openhab. It looks like the Google values are being sent to my mode item which are being rejected since they weren’t mapped. The logs show this:

INFO openhab.event.ItemCommandEvent Item 'Bathroom_thermostat_mode' received command heat
INFO openhab.event.ItemStatePredictedEvent Item 'Bathroom_thermostat_mode' predicted to become heat
INFO openhab.event.ItemStateChangedEvent Item 'Bathroom_thermostat_mode' changed from SAFE to heat
INFO openhab.event.ItemStateChangedEvent Item 'Bathroom_thermostat_mode' changed from heat to SAFE

The docs mention For the translation of Google modes to openHAB always the first option after the equal sign is used so I would assume that the Google values would have been mapped as described in the group GA metadata

Am I missing something here ?

Hi

Thermostats are an issue with Alexa & Google.

It seems that can’t cope with the Power of Velbus :laughing:

I’ve been trying for years, with varying results.

I really need to update my own server to OH5, when I do, I’ll try getting the thermostats running again.

FYI

I don’t do Item to Thing configuration in the MainUI as I just can’t wrap my head around it (and Bulk editing to get client systems up and running is SO much easier with text files.)

However, this is what the CODE tab of my own Lounge GPOD THING is showing
(All my Glass panels with thermostat function activated are configured the same way, Edge lit or classic)

the Code for the Group Item for the Lounge Thermostat looks like this

label: Lounge Thermostat
type: Group
category: heating
groupNames:
  - gLounge
tags:
  - HVAC
groupType: None
function: None

Which looks like this is Google Home

The Mode mapping is important and it works
Heat = Day (or Comfort)
Eco = Night
Off = Safe

But where that Text file mapping is shown in MainUI is a mystery to me.

I’m not sure if this helps you at all, but the MainUI shows this when I open the Lounge Thermostat group

Hey,

Thanks for your reply, i’ve been trying to mimic this as much as possible but without any result.
The mapping of those heating modes to Google Home can be found in the metadata menu of your gLounge group > Google Assistant > Thermostat Modes
There I filled in this value, similar to yours: off=SAFE,heat=DAY:COMFORT,eco=NIGHT,on=DAY

But the behaviour stays the same. I can’t change my target temperature, same for the heating modes.

Can I suggest you do it with a text file, just so you can be 100% clear that what you have configured is identical to what I have working here? (and on other client site)

Once you have it set in a Text file and working, you can look at migrating that to the Mainui method, unfortunately, I can’t help with that as it’s just not what I do to get the basics working.
(imagine all those screen clicks when there are hundreds of items to add, where a copy, paste and sectional text editing can be done in a fraction of the time.
I'm also not 100% sure how everything relates to each other in the MainUI, when it seems so very clear in Text form)

What I am trying to achieve is to identify if the issue is :-

  • With the way the Velbus thermostat is set up within openHAB?
  • Are the MetaTags correct for Google?
  • Can you adjust the target temperatures correctly within openHAB
  • Is is something as silly as the exact utterances to Google

I’m really sorry that this is taking so much effort, it really shouldn’t be this difficult.

Just as a reference

I have tried a series of commands with Google to prove out my own configuration.
The utterances aren’t intuitive, but they seem to work

“Ok Google, What is the temperature in the Lounge”
Google responds with the correct temperature and says the target temperature is 14Âş and the mode is "ECO"

“Ok Google, Set the Lounge Target temperature to 20º”
Google responds "Lounge set to 20Âş"

“Ok Google, Set the lounge thermostat to HEAT mode”
Google Responds, "Lounge set to HEAT mode"

“Ok Google, Switch off Lounge thermostat”
Google responds, "Lounge Thermostat turned OFF"

“Ok Google, Set the Lounge thermostat to 19º”
Google responds, "Lounge set to 19Âş" (But leaves the Velbus thermostat in AntiFreeze mode, just with a new temporary target temperature)

“Ok Google, Turn off the heating in the lounge”
Google responds "Lounge heating turned off" Which just calls the AntiFreeze mode again, which resets the thermostat back to the correct target temp for that mode. EG 12Âş

FYI

If I change the mode or target within openHAB, the new state doesn’t seem to be pushed into Google Home.
However, going back and re-entering the Google Home thermostat does poll the Velbus thermostat and returns the correct (albeit mapped) values.

Thanks! That breakdown via the Google Commands actually helped a lot.
In my openHab I can indeed change all values without any issues. But looking at the logs it was really that mapping part that went wrong.

I think I found a bug in the openHab UI where it puts the mapping string under a “modes” key in the meta data > Google Assistant config of the thermostat group. This has to be thermostatMode since v4.0.0 according to the docs.
Changing it in the code part to

thermostatModes: heat=DAY:COMFORT,eco=NIGHT,off=SAFE

… works like a charm :slight_smile: it doesn’t exactly does what your setup does. When asking for the current temperature, my assistant only replies with the current thermostat mode. But in the app it works ok now

I’m glad that you are a massive step forward.

Try adding an ON map to that, so that when you ask Google to Switch it ON, it has a mode to use,

thermostatModes: heat=DAY:COMFORT,eco=NIGHT,off=SAFE, on=DAY

As for the current temp, have you got that Item included in the Group, with the correct Google tag? ga="thermostatTemperatureAmbient" (does the app widget show the current temperature?)

Group 	Lounge_Thermostat				"Lounge Thermostat" 				<heating> 		(gLounge)			 ["HVAC"]													{ga="thermostat" [thermostatModes="off=SAFE,heat=DAY:COMFORT,eco=NIGHT,on=DAY", roomHint=" Lounge"], alexa="Endpoint.Thermostat" }
	Number 	Lounge_CurrentTemperature 		"Lounge Current Temperature" 		<temperature>	(Lounge_Thermostat, WholeHouse_CurrentTemperature)			["HVAC"]	{channel="velbus:vmbgpod:VelbusNetworkBridge:2C:input#CH33"								,	ga="thermostatTemperatureAmbient" 	,	alexa="TemperatureSensor.temperature" }
	Number 	Lounge_CurrentTargetTemperature	"Lounge Current Target Temperature"	<heating>		(Lounge_Thermostat, WholeHouse_CurrentTargetTemperature)	["HVAC"]	{channel="velbus:vmbgpod:VelbusNetworkBridge:2C:thermostat#currentTemperatureSetpoint"	, 	ga="thermostatTemperatureSetpoint"	,	alexa="ThermostatController.targetSetpoint"}
