Hi,
I am currently in the process of submitting a PR to correctly identify a MP31ZP in zwavejs2mqtt, however upon diagnosis, the device identifier for the 31 is the same as the 21.
To help, it’s been requested that we get the device firmware information from a 21, to compare to the 31, to allow zwavejs2mqtt to be able to differentiate between the two.
Does anyone here have the MP21ZP to hand to be able to get the firmware information?
I’ve tried across the spectrum because they are cheap and in-stock everywhere, 21’s and 31’s have failed and often drop off the Z-Wave network entirely in places my other Z-Wave devices (of which I have many) are fine.
Minoston has also gotten under my skin because apparently they have stolen designs from, in my opinion, the best Z-Wave device make out there - Inovelli. Apparently they partnered up together for some things and Minoston just stole their designs and ran.
The only ones I’ve found to be very reliable are the Dome units (so far). I’ve also installed actual Z-Wave outlets by Leviton but they have also been quite problematic, so back to the Dome plug-in modules again for now.
So many of these Chinese companies change their name frequently, this is the device that has worked well for me, there are a few varieties out there but they are all round, all. have the button above the outlet and may have colors or be all white.
It’s configurable, but it’s been reliable. That being said, they also send anomalous readings sometimes (i.e., millions of kWh), so I use PowerCalc (HACS add-on) for everything now, the wattage is precise but the kWh is iffy, PowerCalc fixes that for me.
Personally I don’t know, I’m not a huge fan of the WiFi stuff, I like to stick to the Z-Wave/Zigbee/Insteon type protocols. Rule of thumb, though, is make sure it’s supported in HA before you pull the trigger on it. Search the forums and if you don’t see anything about it then it’s likely either very obscure or maybe not supported yet.
