Somewhere in the history of the 3.0 there was a change which also affected the child safety unlock procedure. I think the old way was hold feet up and down for about 6 or 7 sec until the backflight flashes and stops. The new way is to press and hold head up and head down for about 6 seconds till it flashes, then do same on feet - feet up and feet down for 3 sec until it flashes. if whichever wag you tried didnt unlock it, then try the other method. If neither way works lol, then try holding head down and zero g button for 3 sec, and then head up and zero g for about 3 sec until it flashes. Hope one of these works! More on reddit.com

The bad news is, I don't know if you'll find one, the good news is I'm in the exact same boat. I'll let you know if I find them More on reddit.com

You should be able to use an IR blaster to learn your remote's codes, then control the bed from the smartphone app. There are many different devices (search for "IR blaster" on Amazon) - here's one example: https://www.amazon.com/Controller-Universal-Infrared-Repeater-Compatible/dp/B07ZP5NQWF More on reddit.com

That is a lovely project! You can do it using Raspberry PI. You have two problems to solve. Communication between RPI and your bed through RF. Communication between Alexa and your RPI For the first one I would check what frequency your bed is using for RF. Most likely it is 433Mhz. If you are lucky and they do use 433Mhz you can get 433 Mhz RF transmitter and receiver and hook it to RPI. This way you can copy the RF codes the remote is sending. You simply enable receiver, and press buttons on remote one by one and save codes as strings. There are python libraries for that. Be aware that you might be out of luck because your bed might be using other frequency or the codes that is sending might be rolling codes (every time sends different code). In this case you would have to disassemble the remote and use relays to simulate button press (as dextersgenius already explained). As for easy communication between Alexa and RPI withou having to use Alexa Skills in the cloud you can install Ha-bridge ( https://github.com/bwssytems/ha-bridge ). It's a simple java program that simulates Philips Hue on your local network. The thing is you are limited to three words "On" ,"Off" ,"Dim". So you would say: "Bed On" to let's say adjust up, and "Bed Off" to adjust down. So what you need is: RPI RF Transmitter and Receiver or Relays Python for communication with your bed (send your RF codes or trigger Relays) Flask - python web server to setup triggering of above codes by using URL (http://rpi/bed_on , http://rpi/bed_off) Ha-bridge where you configure "virtual device" (your bed) and assign urls to trigger for "ON" command and "OFF". Once you have it all running you just tell your Echo to "find devices" and it finds "your bed". More on reddit.com
