Thank you @JDRoberts.
Based in the UK, where it likes to rain a lot, most of the time, without prior notice, so, I assume the Philips Hue motion sensor would be best, due to it’s weather prof properties, right?
Also, does this seamlessly integrate with SmartThings - as an example, I have LIfx bulbs everywhere, connected to SmartThings hub v3, so, just wondering if they won’t be able to talk to each correctly being a competitor?
The Phillips hue outdoor sensor uses zigbee 3.0, Which at present is only supported by the newest hub, and it’s a very new device. So I don’t think we really know how or if it will work with smart things yet, and it probably will not work great with older smartthings hubs.
But you could use a Hue bulb as a “man in the middle” as long as both that Bulb and the motion sensor are attached to a hue bridge.
Have the motion sensor turn on that bulb. Smartthings will know when that Bulb comes on, typically with a lag of no more than five seconds. And then you can trigger other smartthings events because the bulb came on.
That won’t work for everybody, but it may work for some use cases. 
By the way, if you are in the UK, you will not be able to use the Zooz motion sensor anyway as it is only made on the US frequency. The hue motion sensor uses zigbee which is the same in both regions. And if you use it through the Hue bridge, then even that doesn’t matter, as that’s a LAN connection between the bridge and the smartthings hub.
Thank you @JDRoberts.
Thankfully, I have the SmartThugs Hub v3, so this should help with that, but want to avoid purchasing a bridge (or any more hubs, if I can help it).
The Philips motion sensor is available on Amazon, so, once I get a chance, I’ll purchase and do some testing.
Update: some community members are now using the Hue outdoor motion sensor joined directly to smartthings (not through the hue bridge).
@RICHARDNIEVES21posted about this, along with a link to a DTH, in the following thread:
Thank you @JDRoberts. Time to look into it!
After a lot of trial and error the best way I’ve been able to avoid false triggers is to place the motion sensor about 4 feet of the ground (same height as mid torso) and adjust the field of view horizontal or slightly up to avoid seeing the ground or animals.
The Ecolink work very well but the field of view covers high to low and by placing electrical tape over the lower half the ground hit by sunlight is blocked by the tape.
Time to kick this back into life…
So, read the entire topic. 3 possible options for me.

(Maybe, will require some extra cable work for me)

(Won’t work for me, to much moving green)

(The Hue needs a bridge (FAQ: Do you know of an outdoor motion sensor? - #150 by JDRoberts but still not local I asume?) and will work in the cloud? The Zooz isn’t available in Europe, guessing 100-125 euro before I have it here?)
The Zooz won’t work for Europe : wrong zwave frequency. 
I keep hearing rumors that Zooz intends to eventually come out with some European models, but nothing has been officially announced yet.
With Zwave, the frequency of the end device has to exactly match the frequency of the hub or they can’t talk to each other.
As far as hue, For the sensor you have to connect it to a smartthings hub, not a hue bridge. That used to require a cloud connection, but now, with the new edge drivers, it will also run locally. 
Edge itself is still in beta so there might be some glitches, but there is a community created edge driver for the hue motion sensor if you want to try it.
[Edge Driver] Hue Motion Sensor (No Hue Bridge)
If you don’t know anything about Edge yet, read this:
FAQ: I have no idea what Edge is. Is that a new developer tool? (2022)
Good to know US Z-Wave is different! Keep learning here.
But as there is no real outdoor (EU) sensor I’ll look into the Edge thing. Thanks!
Edit: BTW, saw on their site that they are looking for distributors in Europe so maybe…
Might not suit everyone but I have had an outdoor motion sensor for 4 years and never had a single false alarm or failure
Smart power sense plug
External 30w led security light
Cheap external movement sensor
Or you can buy integrated security light with motion sensor built in
Power sense plug to movement sensor, movement sensor to light
Makes everything work smart including automated on off and the sensing part is down to the dedicated sensor
Works 100% reliably and you can trigger an action in ST if power goes above a set limit which is an option in automations if using power sense plug
Yo Link devices are fantastic for outdoor needs and distance, although do not integrate with smarthings directly. Uses diff. Frequencies than zwave. Virtual switches and a bit of workaround thru alexa or google.
Outdoor sensor few false alerts,for a driveway approach, perhaps due to good placement, but could find nothing else working for distance or that would last for inside a freezer for temp monitoring. Mailbox monitoring. Device to device pairing possible for working when internet down.
