I am going to upgrade NodeRed image to the newest version. What do I need to backup before upgrade? I assume i should backup NodeRed configuration, /etc/evok.conf file, but what next? Also, is there any changelog where can i check, what have changed? Thank you!

Ok, thx for answer. Another way is probably to use MCU together with ultrasonic sensor and setup some kind of modbus server on it and than unipi should read from it easily, hm? Am i right?

Thx

Hi,
Is there a way to connect and read distance from ultrasonic sensor like this one?

Hi,
I have a question regarding difference between neuron and unipi gateway. I am thinking about control system of my home and decided to use HomeAssistant as a heart of my home smartness. The question is, how to read switches and make actions like switching lights on/off, running window blinds and so on. I am little bit confused, if i need eg UniPi Neuron with installed HomeAssistant on it, or is better way just to have UniPi Gateway with Extensions boards connected together and using modbus plugin at HA to read/write from/to extensions board ports. Can you help me with decision pls?
Thx
