Integration of z-Wave /danfoss thermostatw

To conclude on this topic, for a modest contribution (the equivalent to few cups of coffee-especially at Starbucks), you get something that I’ve built over several hundreds of hours of development & testing (the latter is critical)…

Yes I can see we’ll have to agree to disagree on this one

Good luck with your continued efforts

BTW, somebody sent me some IDE screenshots of the danFoss thermostatw DTH, and the DTH lacks some basic thermostat capabilities & attributes (i.e., thermostatMode, thermostatOperatingState, thermostatFanMode - even if the attributes don’t always apply, they should be present).

I don’t know who is the DTH author, but she/he should modify the DTH to make it more standard. Otherwise, no other smartapps can use the thermostat as it is.

EDIT: I found this DTH that seems to be more standard:

Yeh! That’s my device handler. I can confirm that it works well and I’m actively maintaining it.

I’m using it manually and have used it with a scheduling smart app as well. It has the full thermostat capability for use in apps. It also has the ‘switch’ capability, which means you can turn it on and off, if the smart app or something can’t use the thermostat capability.

Neil_McRae · October 13, 2017, 10:29am

Thanks Tom.

What smart app have you used currently to set the scheduling?

tommysqueak · October 13, 2017, 10:43am

I was using this [RELEASE] 5-2 Day Programmable Thermostat Scheduler (Weekday, Weekend) with Remote Temperature Sensor for each Schedule for simple weekday and weekend schedules.

They have a paid for version, that does more and I think can use a temperature sensor.

yvesracine · October 13, 2017, 10:47am

Hi,

ScheduleTstatZones can also use temp sensors and motion sensors (to see if the room is occupied or not) to adjust the setpoints…

You can even use an outdoor temp sensor to define some more/less heat thresholds.

And, many more features (ex. alternative cooling, can change your fan settings at the main thermostat based on some outdoor or indoor conditions, etc.)

Hi Tommy, I am using your DH. Its great - thank you. I do however miss the report from the device. I am not sure if my LC13’s do wake up every 15 mins as i have told them to. I have had problems with the messing up before.
Do you know how i can check the wake up interval? Thanks!

Danny

Hey @tommysqueak. Thank you for your hard work to date, I have been driving x15 of these radiator valves with your driver for a while now.

I am curious if you have tried the official driver now available from smartthings for the Danfoss Living Connect valve and what you think of it compared to your driver? I haven’t myself, and would only want to move if people thought there was a significant upside.

Thanks

Paul

tommysqueak · October 23, 2017, 9:52am

Hi Danny,

I remember having issues myself with the wake-up interval. It always seemed to be stuck at 30 or 60mins. I can’t remember how I eventually fixed. This might help https://github.com/codersaur/SmartThings/tree/master/devices/zwave-tweaker I haven’t used it myself but I bookmarked it a while ago as a useful tool to interrogate devices.

I also think there’s a bug with the handler, in that because it’s a sleepy device the configuration changes don’t get sent when you save them, unless it’s awake. You can try waking the device manually and then immediately saving the a new wake-up interval from the config screen.

Hope that helps

tommysqueak · October 23, 2017, 9:55am

Great to hear the handler’s working about

I haven’t heard of the official driver! Do you know where the code is or any other info? Be good to check it out and see how with inside knowledge how they approached it. With the lack of documentation, mine was based on a lot of sitting next to the radiator with trial and error.

peastabrook · October 23, 2017, 10:17am

haha… very grateful to your trial and error @tommysqueak.

Yeh, it is an official Thing now. So you will find it listed under:

smartthings app/marketplace/things/home environment/Danfoss Living Connect

It would be great to get your views on it.

Cheers

Paul

Hi,

I have just bought a Danfoss valve but I’m not able to pair it into the Smartthings. When I click into add new thing I can’t see Danfoss valve, could you please help me on that?

Thanks.
Regards.
Javier.

Hi all, firstly this is a brilliant thread! Been really helpful in planning the move into controlling my rads.

This morning 14 Danfoss TRVs arrived at my door. I managed to pick up the 014G0012 ones with software 2.51 (according to the battery cover). The one I’ve got on a trial radiator was recognised immediately by smartthings as the LC-13 (happy days).

I can see that Brumster has successfully used these TRVs, I was wondering if the default handler is best to run them or if the DTH mentioned in this thread is more reliable or offers any benefit?

Many thanks

Louis

Hi guys!

I just joined the community and, well, I’m a total newbie in ST (received my 2nd gen hub today)

I’ve managed to connect the Danfoss Living Connect to my hub and I’ve downloaded the follow device handler:
tommysqueak : Danfoss Living Connect Radiator Thermostat LC-13 v3.01

My problem is that when ever I try to switch the Connect off via the SmartThings app, it doesn’t work. How come? What I’m I doing wrong?

I’ve tried to read through the entire thread, but it’s really difficult to find any answers to my issue.

Thanks in advance!

// Mads

brumster · November 21, 2017, 5:25pm

@MrRhubarb its a battery device. It therefore polls at a regular interval to pick up its config (and any SetPoint changes). Have a look at the setting of the device and it there should be a refresh time. Check the log for the device and you should see it wake and update.

@Louage with regard to the DTH. I have;t tried the default handler. I installed mine before ST started supporting the TRV. I’m still using @tommysqueak 's handler. That allows me to set an ON temp and an OFF temp, fits my use case perfectly.

tommysqueak · November 21, 2017, 5:45pm

Good places to start are the logs at https://graph-eu01-euwest1.api.smartthings.com/ide/logs To see if the sleepy (battery powered) device is checking in, the app sets it to 5mins but I think the default is 30mins, so it might be checking in at 30min intervals. If you press a button on the actual thermostat, it will checkin and you can see some action in the logs.

MrRhubarb · November 21, 2017, 5:55pm

Thank you so much for the quick reply

I’ve just checked the log and it update perfectly:

Maybe I’m just having difficulties understanding the following parameters:

On the app I’ve set it to 28 celsius (also on the the Connect itself) to test if the Connect starts turning up the heat, but when ever I press turn off, it does not respond. I’m kinda curious if the manual setting on the Connect interferes with ST?

Sorry for the lack of terminology… I guess it will come late

tommysqueak · November 21, 2017, 5:55pm

I was able to check out the official handler at the weekend and took some screenshots of the differences.

I had my eye saver app on, so apologies for the pink tinge in the screenies.

Luka’s radiator is using my handler.

The custom handler supports more capabilities. Like the ability to behave like a thermostat. So widening the range of smartapps you can use to interact with this, as if it was a thermostat eg Google Assstant. Also the switch capability allows smartapps to treat it as a switch and turn on/off. eg routines can turn the radiator off.

MrRhubarb · November 21, 2017, 6:55pm

Thanks for the answer

It looks like it’s checking in if I go to the device itself (the screenshot from my first post) - I might be mistaken
This is what I’m shown via the log link:

I’m using your handler from GitHub (which looks awesome), but how come I’m not shown the same “Current States” when looking at the device through the web GUI?

I might have missed a point, but what I basically did were to:

Install the Connect
Find it via the “Add a Thing” button
Published your handler using “From Code” to my hub
Open my Connect via the ST app and tried to controll it
