Your TV might not support the keys hdmi1 and hdmi2... unfortunately samsung's inofficial api is pretty inconsistent across devices. Can you try the hdmi key (without number)? This might also be the reason for not being able to turn off the tv, the library tries to find out if your tv is turned off with KEY_POWER or KEY_POWEROFF (in your case it uses power as you have a H-Series as far as I remember). Maybe your tv has to be turned off with power instead...

yes you are right, the KEY_HDMI key works for my TV, it switches the HDMI inputs one by one, thanks!
but I still have a problem with the big POWER button
maybe you have another solution to fix this?
as an example

     "platform": "SamsungTVControl",
     "devices": [
         {
             "usn": "uuid: ---",
             "token": "eyJz ---",
             "name": "TV Sumsung 55",
             "customKeyForPowerButton": "KEY_POWER", // <- some like this
             "inputs": [
                 {
                     "name": "HDMI",
                     "keys": "KEY_HDMI"
                 },
                 {
                     "name": "MUTE",
                     "keys": "KEY_MUTE"
                 },
                 {
                     "name": "POWER",
                     "keys": "KEY_POWER"
                 }
             ]
         }
     ]
}
