[QUESTION] What exactly is --gateway?

[wsw70]

From the README:

Before you can use the tool to setup your device you need to put it into paring mode and connect to it's Access Point. It's IP address is known as the --gateway parameter and is typically 10.10.10.1.

I recently paired a device and was confused by --gateway (it's been a long time since I paired something). The README mentions that this parameter is its IP address.

Which IP address, exactly?

• is this the address of the access point, and I will get an appropriate IP upon joining the AP SSID? (in which case I should never need it)
• or is this the IP address of the paired device? (once it has rebooted and joined my own network). I used it in that context to get information about an existing and running device:

PS > node .\bin\meross-info --gateway 192.168.10.183

Getting info about device with IP 192.168.10.183
(then comes the table with the device info)

--gateway is the IP address of the device at any point in time.

During pairing the IP will be typically 10.10.10.1 and does correspond to the gateway IP that you see when connecting to the WIFI access point the device broadcasts. Later the IP corresponds to the IP the device is given by your network, and in theory the tool could be used to change the MQTT data of an already configured device.

I do understand your confusion, perhaps better documentation is required.

I have updated referenced to --gateway with --ip in the rewrite i'm doing https://github.com/bytespider/Meross/blob/be2a70ba759278e4956478b95419df3de219c625/bin/meross-setup.js#L40-L44

the -a (for address) may not be a short hand for --ip. I'm undecided at the moment.
