Hi rose customer service
Any chance we might get Alexa control in the near future for rs150b . Iam sure you clever boys and girls could do it , 
Keep up the good update work 
We tried to support Alexa control. However, there are difficulties in applying. We’ll keep trying, but we’re not sure.
Hi Rosehen
Thanks for your reply and hard work .
Just power on/off , volume, and input selection. Would do .
Regards pete
