Hi Ed,
From what I"ve seen they come with a wireless remote. But unknown if it is IR.
When it’s an IR remote, you can consider purchasing a Broadlink RM 3 (or 4) mini (IR), or RM4 (IR + 433MHz RF).
With one (or more) of these you can learn any IR signal and send it with Homey, with the revived Broadlink app.
You can use a Switchbot hub as well, but it’s pricier. You can use the Switchbot app to control it with Homey.
And I’m not sure if one unit can reach all 4 TV lifts without obstacles.
