Since Z-Wave Long Range functionality is still new, I thought I'd start this thread where we can share observations and notes, about how it's working (or not) for you. This is after you get it working and successfully add LR device(s).

Here are my notes so far, including my initial observations first reported in the ZMatter dongle firmware update thread (and lets keep using that thread for "getting it to work".

Testing of LR range: a bit disappointing. I don't know how this compares to a Yolink device, but going through concrete foundation walls seems to really limit range. I first tried my Shelly LR device where I usually plug in my pool pump, which is the corner of my property. Two inside walls, two concrete foundation walls (the house has been expanded) and through two walls of an aluminium above ground pool. Total distance, about 80 feet. No go. Next was in the standalone garage, which subtracts the two pool walls but adds steel cladding on the garage, About 60 feet. No go. Next was inside the basement workshop, which brings it down to just the two inside walls and one concrete foundation wall. That works. Now I'm testing this with my trusty test Polisy, which is near my computer in the basement, and the dongle is at desktop level. I suspect that moving the dongle higher up, ideally above ground, would help. I'll test that when I implement the LR function on my production eisy, it's dongle is almost at ground level.

Update: I now deleted the Shelly device from my test Polisy and added it my production Eisy. The dongle antennas on that one are higher, just below the ground floor joists. I retested the garage location as described above. The higher dongle location eliminates the need for the signal to go through foundation walls. It now works, but there is sometimes a delay (up to a couple of seconds) before the on or off status updates in eisy-ui when I send a command. So LR is likely doing some kind of retry on communications. The same module responds immediately when it's closer to the dongle. I'll be retrying the pool location later. The pool location is interesting because I also have a Yolink hub near my ZMatter dongle, and a Yolink temperature sensor at the same pool location. It's been quite reliable though not perfect. This will allow me to compare how well the two long range technologies work.

Today I got to do the test of putting it out near the pool. Same results as with the garage: it works, with the odd update delay every now and then. I do like that it does what's needed to get through, repeats or whatever.

I also did a bit of Google searching on the subject of Zwave LR vs Yolink, and the general consensus seems to be that Yolink beats out LR on the reliable long range communications.
