I got a JBL Flip 3 speaker. Currently, we cannot power on the device remotely. I have to get up from my couch and do it manually. Is there a way I can build that feature and add it to my speaker. Like get a low power bluetooth module and somehow connect it to my speaker (via 3.5 mm jack) and program it to turn on the speaker whenever other devices try to connect to it.
P.S. I realize it may mean opening and messing up my speaker's internal circuitry and I am open to options.
Best way to do this is actually by networking your home power grid connecting it mobily using Wi-Fi instead of Bluetooth. There's apps pre-designed once it's all connected and most top companies selling kits already have special apps to download from their sites. Or you can be like myself and many others and create your system yourself but only if you are knowledgeable about Electricity along with Radio Frequencies and Electronics.
Once installed then it's like living in the movies like IronMan for example because instead of tapping buttons using Bluetooth you instead can use your voice. Ever wanted to walk into a room and just say "Let There Be Light" and then there was Light?
You'll also be able to turn on/off your lights and anything else in your home even open/close your garage door or lock/unlock any door all from your phone. If you're really into digitalizing everything like I am then you can even program your own PCB adding it to lets say a Coffee Machine commanding it to grind and brew your fresh coffee using your voice while driving still 5 miles away. The possibilities are endless with these setups. Setting it up is a pain in the ass but once you're done with the main initial setup you'll wonder why you didn't do it years ago because its worth more than any house its in but costs pennies doing it yourself.
