New Uni-T UT61 series (UT61e+)
Fungus:
If safety is of primary importance then maybe a Brymen is better, eg. the BM235:

Mostly arduino stuff, electric Motors and repairing items. (Electric motors around 4kw)
I like the idea of data logging and I was looking at the BM235 but I dont know.
How unsafe would the UNI-T UT161E be?

I found the DC accuracy to be excellent, comparable with a SDM3055 !! From 50mV to 60V it was never off by more than 4 counts !!
I have a calibrated Resistor Box and from 1.0 ohm to 1.0M Ohm it was an order of magnitude better than the spec.( 0.5%+10)
AC is arguable, since I have no calibrated source but it looks good too. It is spec'd to 10KHz but accurate to >100KHz. (-3dB @ 700K)
Frequency is usable to ~70Mhz if you blast it with 300mVrms, and only 10Khz resolution. Sensitivity at 1Khz is ~100mVrms.
Caps seemed to be in spec (3%), and agreed with the SDM3055. Still need to test the current and diode measurements.
I will not use it for NCV, it really lacks sensitivity. The loud beep for 'turn me off' is a bit annoying, but can be turned off.
I was able to get the USB working on Windows10, but not on Linux which is a big disappointment.

The UT161E is third party certified, so at least you would have a meter that was subjected to tests and do not only depend on the manufacturer's own word for safety.
For the Arduino part, you shouldn't need much else other than a plain UT61E, but the 4kw motors can change the game. I would not necessarily have a problem using the plain UT61E on this scenario, but since I don't know your experience, the more conservative assumption is to keep the recommendation to a certified multimeter.
The UT161E, however, gets dangerously close in price to the excellent Brymen BM857 and BM867 (tme.eu), both edging the UT161E in features while having the weight of an excellent and reliable brand. With a loss of counts but at the same price range you have the also excellent BM257.
Good luck in your quest.

Thank you my questions are answered.
