I am using this with a 2021 Hisense Roku TV. If the TV has been off for more than an hour, the "ON" button will not "wake up" or turn on the TV. I checked for fresh batteries. (By the way, it doesn't come with batteries). I need to turn on my TV with Roku's original OEM controller. After turning on the TV, this controller works normally. 2021 Hisense Roku TVs have multiple shutdown modes. I changed the settings and now the controller works fine.
