Build the Satellite1 Together
What can I say. I saw the early stages of this whole project, and I was hooked from the start. Yes, it did take ages to arrive in the UK. (Thanks Customs!!) But it's here, and it's been worth the wait. I'm not a tech genius, but I do like to make the house do things without me having to leave the sofa. The set-up is an absolute breeze, IF you follow them. Don't rush like it did, only to realise you might have just connected things the wrong way round. But the incredible support was at hand to allow me to admit I was being a numpty. (So grateful support 6*s). There is some assembly and ideally a 3d printer, but that's half the joy. It's like Lego, but for smart homes. But seriously, IF you are looking for a solution to allow you to microwave your Alexa devices, then you need to seriously consider this option and and join the journey to a future proof home.
My last review pointed out the antenna "limitation" - so I addressed it by soldering a small wire to extend the antenna and it helped a lot. I would still prefer something like an ESP 07 with an external antenna option (for an example) - but its all good now. Its impressive with the right server running HA - nothing cooler than talking to, and hearing, Jarvis as your home assistant :) Thanks for the great product! Looking forward to the add on LLM and adding more speakers to my setup (with my SLA printed Jarvis painted speakers - in Iron Man colors)
Nice PCB and seamless integration in HA.
Patiently waiting for Nexus1 to finally ditch Alexa.
I wish I had gotten the mmWave sensor.
Very impressive. Documentation to get up and running was excellent. Performance is great!
