Horstmann HRT4-ZW thermostat

[Mdamen]

I just installed this device this weekend, after hacking around on the software side for about a week. As far as a I know its the first european z-wave thermostat.
The device has some trouble in Homeseer and with Vera as well, hope they will fix it soon. It does work nicely now in my own software (HouseAgent), I will blog about it later this week.
Here is some more information about the device: horstmann.co.uk/downloads/ElectronicDoc ... ataweb.pdf

It allows me to do everything I want to do with my thermostat:

- Control the setpoint
- Get a setpoint report when it is manually changed (also notifications of battery levels and the room temperature)
- Get the actual room temperature

The setpoint takes a maximum of 4 minutes to get to the device, as a setpoint command is queued and sent to the device once it wakes up.
All and all a nice device for only 90 euros.

Looks good. I hope that it will be working in Homeseer soon. Seems to be good alternative for the Proliphix which is expensive and very hard to get.

Good to hear that it's working.
I will open a ticket for the Homeseer support in the next weeks.
Same probleem as the Danfoss radiator valve.

Maarten,

Where did you buy it for only 90 euro ? I found one on zwave4u.com, but it's 102 euro.

Regards,

Soitjes.

You need to set configuration parameter one:

Configuration Parameter Number 1:
0-127 disables temperature sensor, 128-255 enables temperature sensor. Default = 0.

Thanks for the explanation Maarten. I get the following error in HS, I dunno if it's the lack of support of that I'm doing something wrong. Maybe someone can help?

When starting HS up:

In the Zwho overview I see this:

The Horstmann HRT4-ZW thermostat is not fully supported by Homeseer yet.

I am considering getting the HRT4-ZW because on the HS board it seems to work.

How do you guys deal with the lack of scheduling in the device, did you create one in the control software? Does that mean you will have to create an event for every change you need?

My zwave devices are read in Merten software first. I use the aeon stick as secondair device.
Do you know of the this thermostat will work in this configuration for 100%?

Probably not. The reason for this can be that Merten Configuration software don have support (config. files) for the Horstmann device.
As result you will get some Not Reliable device in merten software that will be not possible to del. But of course you can try.

Hello everyone, my name is Martin and I'm new to both the forum and Domotica. I'm from the Netherlands and I just ordered the HRT4-ZW from the UK. To start with Z-Wave home automation, I'm still looking for the right USB interface (and software package, I'm now aiming for Z-Cloud) too make this thermostat remotely controllable, looking forward to it!
