Legacy Neeo is well alive.
I bought an old neeo remote (2nd hand) this late December 2019. I was a bit desperate to see that all neeo cloud services are fully down and thought I bought a paper weight.
Yet, thanks to Niels' posts and the sdk provided by neeo, I am now able to run everything in my house (Hue, Air Con, Mi TV, Yamaha Receiver Xbox One X). I use a Broadlink Mini 3 (blackbean) for all the additional IR stuffs and a Raspberry Pi.
It works exactly the way I want as I developed it myself (with the extensive help of posts in this forum) and overall I am surprised on how easy it was.
For the record, I was not having any experience in the sdk programing language (node.js) and a very very (very very) distant background of developer.
