Greetings! I’m new to home automation and had a question i couldn’t seem to find an answer for via search function. I have a Ecobee 4 and an LG smart A/C (https://www.lg.com/us/air-conditioners/lg-LW1817IVSM). I can create schedules via the LG app to turn the a/c on and off, but that function works regardless of the room temperature; It simply knows to turn on at at 2:00 pm and turn off at 10:00pm. I can control every function of this A/C via the application on my phone, or via Alexa. Now, i don’t own a smart things hub, or know much about it, but I’m familiar with basic logic programming. Would it be possible with this hub to turn my A/C on when the thermostat reaches X, and then off again at y, only during certain times? IE to act as a bridge between the two? I know that may be a tough question to answer definitively, but perhaps somebody here may know. I see nothing from LG under the list of compatible devices.
You probably want to contact Ecobee and see if they have any luck with it. If the LG Smart A/C worked with Smartthings, you might be able to use it to translate between the two.
For the last 4 years, I’ve developed My ecobee Device and my smart zoned heating/cooling smartapps with those kinds of capabilities in mind.
Some of my contributors to my code have a similar configuration: they want to use their ecobee thermostat as a master thermostat for their home and this includes controlling slave thermostats (such as portable heaters/coolers/mini/window split units) for hotter/cooler rooms.
With my device handlers for Ecobee and your portable heaters/coolers/window/mini split units controlled by the Flair puck, my smartapps can integrate them by leveraging their capabilities under the ST platform.
First you need to check with Flair (contact support at flair.co) if the LG Smart ThinQ is supported (it should be as LG is a major brand, but they may not support all models). If so, you’d need 1 puck (hardware sold by Flair) as the puck uses IR to control the unit .
Second, you’d need the following bundles at my store:
- My HVAC unit bundle will expose the Flair Puck and your LG SmartThinQ unit as a Thing under ST - My ecobee bundle which includes My ecobee Device and the _ecobeeSetZoneWithSchedule_ nsmartapp
The HVAC unit bundle, you can expose your LG unit to SmartThings as a thermostat and a switch, so you can control it by turning it on/off manually (using the DTH) or define a setpoint (target temperature).
For the unit:
For the puck:
The zoned heating/cooling smartapp called ecobeeSetZoneWithSchedule can control your LG unit based on the master ecobee thermostat and the concepts of rooms/zones/schedules.
The smartapp can turn on/off multiple units based on your active (using your motion sensors) scheduled zones at your home and keep the slave thermostats’ setpoints in synch with your master thermostat.
Most people use splits for cooler/hotter rooms and still have a master thermostat for central heating/cooling.
For more details on My Ecobee device, and all the use cases supported by ecobeeSetZoneWithSchedule, refer to the ST community wiki (under the configuration section) :
All the bundles are available for download at my store:
My Ecobee device has been used by thousands of users and there are many Flair users as well, see my threads here:
