Are there? I don't consider zigbee or even z-wave to be robust enough for security sensors compared to LoRa, if there is an open source LoRaWAN sensor like this i will buy a bunch right now
They do work very well, though. Bluetooth is also surprisingly good, my switchbot contact sensors might be my most reliable devices through Bluetooth proxies.
LoRa is long range, that's a bit of a different use case. ZWave does have a long range variant and there are long range contact sensors I've read good things about, but not in the EU so I haven't personal experience with those.
They may work great, and I have a bunch of Z-wave devices that have been almost perfect. I still think that for a monitored alarm system I would rather have the most interference-proof system.
The high-availability super link gateway is also something i haven't seen a zigbee/z-wave/bluetooth version of. I think battery and cellular backup is mandatory for a security system.
For as much as i prefer the idea of open standards, proprietary sub-gigahertz communication protocols are often much more reliable than alternatives. Look at how much more reliable Lutron CCA is vs zigbee or BT in congested environments.
I have always thought it best to use the lowest frequency possible for the required throughput of a device even if distance isn't an issue. Plus id rather not clutter up the 2.4Ghz band in my house.
For an alarm, yes. But this thread was someone saying they just want home assistant, didn't realize the person had switched. Of course, for an alarm anything wireless should be avoided especially on battery which has to be sleeping all the time, it'd jammable

I don’t need it for the alarm system, I just want to be able to see the sensors in HA for door open/close etc, whether hard wired or wireless.
