- 8fingerlouie 27d agoI use Home Assistant to turn on/off the TV via automations, sensors, etc. I could possibly do it via HDMI CEC, but I have a couple of Sony Bravia TVs that more often than not completely ignores that, so I prefer having control over assuming it happens.
- 05 27d agoYou can do on/off using an IR blaster (broadlink integration with discrete on/off codes). It’s when you want to read volume etc things get trickier
- _flux 27d agoI have an automation that turns on amplifier only when using certain inputs, not just when the TV is turned on. I can easily imagine people would also configure their amps to use different input depending on TV input.
- harha 27d agoYeah CEC is a bit tricky sometimes. How about auto-off from the TV itself and then a timer for a HA controlled outlet to turn off power after that using automation (i.e., when the streaming device is off for a x minutes)
- spockz 27d agoPut the tv on a zigbee/matter plug and connect that for the power. (Just be mindful that some TVs need to condition their screens and they will do that when turned “off”, typically during the night. So it you do a hard power off you will need to perform it manually. LG calls it OLED Care iirc.)
- Asmod4n 27d agoThere is sadly no hdmi CEC support on Most GPUs for pcs. So when you want your tv to turn on and off with your pc it is only possible with the tv being reachable from your pc via ip. I believe LG doesn’t advertise such an api via Bluetooth
- 05 27d agoHDMI breakout and a esp32 module flashed with esphome is another option. The tv most likely doesn’t care that the port that sent on/off command is not the same port the video signal is coming from..
- Asmod4n 27d agoThe tv does care which port it came from, since it automatically switches to the one which made the request. One could build a IR emitter but you need soldering skills for that or buy a usb one which cost north of 30€ + shipping.
- fanatic2pope 27d agoYou can get USB controlled CEC injectors for HDMI. https://www.pulse-eight.com/p/104/usb-hdmi-cec-adapter https://www.pulse-eight.com/p/104/usb-hdmi-cec-adapter
- account42 27d agoFor a 4K120Hz TV I'd be worried about this adding signal integrity issues - "all versions of HDMI®, including HDMI® 2.0a" doesn't inspire confidence.
- FireBeyond 27d agoMy understanding is that CEC can be received on any alive interface, not just the active.
- colingauvin 27d agoYes but you will lose 120 FPS/VRR. So for high end TVs not really ideal.
