That was going to be my next attempt, but it seems risky. Will home assistant recognize it as the same device when I plug it back in?
All the backups in the world won't save me in that case. I haven't eve n been able to confirm what firmware versions there are. I don't want to have to start from scratch sawping the dongle back and forth.
I guess I was hoping I was just missing something.
I think this is the way too. I have never updated firmware on a device via the Pi. Always connected to a PC.
Can you confirm that you do not have ZHA and Z2M running at the same time?
- Disable ZHA
- Uninstall Z2M
- Reboot device
- Reinstall Z2M
- Try to run it again.
That's what I would do next.
I believe you have to disable zha before you attempt to flash. You can't have something actively working with the adapter while trying to flash it. The easiest way is to just drop the adapter into a desktop computer.
If you are looking to use Z2M you have to stop ZHA. You can't have two different software packages attempting to access a single adapter, it's basically like trying to flash while in use. Alternatively you can buy a second adapter and use that for Z2M and keep the original wiring with ZHA.
I see that folks are trying to be helpful here, but I think that you're making it far more complicated that it needs to be. ZHA supports the SLZB-07, and the manufacturer supports ZHA. It seems to me that the path forward here is to figure out how to create automations first, which is not exactly straightforward. It'll be easier to figure out the issue if you can point to exactly what's not working, if anything.
Otherwise, there's a strong chance that if you get the adapter working with Z2M, you'll be back at square one trying to create an automation, but more frustrated.
I have some automations using ZHA as the, I don't know what it'd called, the device is the coordinator, ZHA vs Z2M is a ___? Anyway I have a couple automations but mostly plugs for monitoring energy usage, in order to really start to expand usage I got the tuya remote and that's where things started to go south.
