Honeywell Lyric Thermostat

Post by marcoschaap » Friday 02 March 2018 22:11

Hi!

Short version on bottom!!

I'm the owner of a Honeywell Lyric T6 Thermostat and I'd like to be able to control several features / retrieve some information off the device. I did some testing with the API of Honeywell on: https://developer.honeywell.com/api-met ... ags_tid=39, but fairly soon I realized that a simple HTTP GET or POST wouldn't do the trick because the usage of OAUTH authentication method.

Afther that I've searched for some scripts in Python or LUA to get info or set some options for the thermostat, as I'm not exactly a script star, that project died a soon but certain dead. I've searched for some news on the support of Lyric for Domoticz and found a few old topics that didn't seem very hopefull.

As for some background I'll try to explain my Home Automation and specific needs for the thermostat integration:

I started using Domoticz last year July for monitoring my Solar Panels (Omnik converter read by from Domoticz Wiki Python script). Soon after that a Landis Gyr Smart Meter (Electric and Gas) got installed in my home and I've started monitoring it by reading values from the USB P1 Meter. Also in July I've let install a solar boiler with central heating support, which I'm monitoring via DS18B20 temp sensors in combination with an Universal Binary Sensor from Fibaro via Z-Wave. I measure the hot water outlet, central heating supply and central heating return channels.

Now I'd like to be able to heat my house adaptively by monitoring Solar Boiler temp using Blockly. Also for measuring Gas usage per degree day I'd like to be able to read the current measured temp by the thermostat. The thermostat shows all received OpenTherm values in an "advanced OpenTherm menu", if possible I'd like to be able to read the requested central heating temp to compare Delta T values for the return feed.

Short version :-)

I have a Honeywell Lyric T6 thermostat which I'd like to control in Domoticz. Please see the Honeywell Developer Portal for an API guide here: https://developer.honeywell.com/t-serie ... stat-guide

Options I'd like to control:

- Read Indoor Measured Temperature
- Read and Set Current Setpoint
- Read OpenTherm properties
- Apply Blockly actions to the Thermostat, so I can adaptively heat the house by using solar heated water

If I forgot something, bored you to bits or you want to hear anymore about My Domoticz configuration do not hestitate to reply or send a message :-)

Thank you in advance!

I don't know who, but somehow somebody implemented the Indoor/Outdoor Temp sensor / Temp Setpoint for the Lyric in the latest beta build!! I'm very gratefull for helping me with this. Thank you very much!!

Wow! that is amazing! It worked for me straight away.
Only one problem, here in Australia I use the Cooling side of the thermostat much more than the heating.
do you have any more information?

I'm not really experienced with the cooling capabilities on the device. For me it looks like the Switch (Heating) On or Off situation defines whether heating or cooling is active. But offcourse I can be totally wrong here, I don't use cooling at all here in The Netherlands, most of the time it rains in the summer :lol:

Hi Leon,

Running Domoticz Béta v3.9047 on a Raspberry brother (Solidrun I2EX) on ARMBIAN 5.38. Are you running stable or another platform?

Kind regards

To get both the tokens press the "provide" link and enter the credentials associated with your Honeywell account (same credentials as entered in the Honeywell Lyric App). If you copy / paste the tokens from the website and after that Add the device, 4 devices will be created for the hardware.

Is that the latest stable version? You could try to update from beta channel. You can change the option in Settings --> System Tab --> Option Software Updates. I don't exactly know if there are any Bèta versions for Synology, but you could always try.
