Aqara sensors & node-RED

Image
It turns out, like usual, I bought things in the past that I was going to use for something, either it didn't happen, it didn't work as I wanted or I just forgot / didn't have time. This weekend, I noticed that I had a sonoff usb dongle that looked quite funky - I vaguely remember buying it to see if I could "sniff" the new electricity / gas "smart meter" that had been fitted.   I still have issues about the BS that relates to the companies referring to them as "smart", there is nothing smart there at all, it is just micro-managing the monitoring of the household usage, looking for patterns, identifying your electrical items, determining what you have and how to make the most amount of money out of you - so, yes, in the sense of "smart" it is for the company, not for you the consumer. Anyway, I was wondering, I need to do something with a vibration sensor with node-RED, so I thought, hey, let's see what is available for sale that ...

Node-RED is coming of age

I've been using Node-RED for over a decade now ( here's a post to "prove it"), I've used it personally on Raspberry Pi devices, on robotic platforms, I've used it in Enterprise grade level clients across Europe & Africa to manage smart buildings, improve process flows & distribute / parse data to where it needs to be to make informed decisions.  I even had it running on a prototype BMW i8 in Munich at one point, talking to an AI tool :-D A couple of years back I even used Node-RED hooked up to a 1979 Atari 800XL to connect to the internet / LLMs , just for fun - but it did show just how powerful, quick & simple it was to get that all important "integration" working from an idea into a proof-of-concept to a demonstration. I often hear the sentence, "oh, but node-RED is not scalable. It is not able to handle 50,000 messages a second processing, etc..etc..".  Well, as I inform these ignorant people, "do we need to?".  th...
