The existing decoder works fine but some remotes based on the same chips transmit using FSK instead of OOK.
I own one of such remotes so I initially tried running rtl_433 with this custom decoder:
rtl_433 -R 0 -X 'n=hcs200,m=FSK_PWM,s=370,l=772,r=9000,g=1500,t=152'
I confirmed that it works but it's a bit inconvenient, I'm not sure if adding a separate device protocol is the way to go but it might be useful to somebody else.
