@IP_FINAR

is it better to go for a “fancier” case with fans ?

If you live in a very hot climate zone: yes. Otherwise not really needed.

@IP_FINAR

which size would you recommend ?

@rlkoshak

16-32 Gig.

@IP_FINAR

does it required a power cable/adapter

@sihui

a power supply, for example an unused usb charger. And an usb cable to program/flash it.

BreadBoard for testing… (any recommendation?)

See above or

Newbie: which version of Ubuntu for installing OpenHAB?

If your budget allows may want to look at getting some of these. Mini Breadboards I love them. You can set small projects up then and keep them. Just thought I would pass it on.

BreadBoard Power Supply

Not for the nodemcu. it is powered via usb power supply.

@IP_FINAR

Volt-meter… (what specs should it have?)

A simple one if it is really needed at all. Depends on a good or bad manual for your alarm central.

@IP_FINAR

welder (which one) ?

Soldering

Around 50W, temperature controlled would be nice.

@IP_FINAR

does it make sense to get a “starter kit” something like this:

Depends on your budget. Sometimes there is useless stuff in there.
