Bug: Failed to connect to Roomba on different subnet even though static IP provided to plugin

[deleto]

Describe The Bug

Fails to connect to Roomba which is on a different subnet from Homebrige, even though I provide the static IP address of the Roomba. Does not list Roomba on DEVICES tab of the UI.

To Reproduce

Place Roomba on different subnet (192.168.4.xxx) from Homebridge (192.168.3.xxx).
Ensure no router firewall rules set up between these subnets.
I happen to be running Homebrige on a Synology NAS.

Configure the Homebridge Roomba plugin using the Homebridge UI alone. Provide the Roomba's static IP, BLID, and password.

Expected behavior

Homebrige Roomba plugin should be able to connect to the Roomba.
This has worked for me previously with a different Homebridge Roomba plugin.

iRobot iOS app connects successfully from the same subnet as Homebridge (192.168.3.xxx).
Homebridge Roomba plugin script roomba:getpassword also works fine and yields the expected Roomba password.

Workaround

Move the Roomba to the same subnet as Homebridge. The Roomba is then listed on the DEVICES tab of the UI. Aside: why is the IP address listed in the "Serial Number" field?
It works when I continue to provide the details of the Roomba (updated static IP 192.168.3.xxx, BLID, and password).
It also works when I remove the details of the Roomba.

This could be part of my issue as well, except that my Homebridge host is dual-homed, and the Roomba is on the secondary interface, so no routing is involved.

[jlg89]

Bug confirmed. This is on a dual-homed host, directly connected via ethernet to two different subnets (IOW no routing is involved here). Homebridge talks to HomeKit on the primary network, and all the IoT devices, including the Roomba, are on the secondary network. The plugin successfully logs in with my iRobot account, pulls the correct blid, and then can't find it on the network (I assume) because the plugin is only searching on the primary interface.

I also use the homebridge-tplink-smarthome plugin, and it is configured with the parameter:
"broadcast": "192.168.x.255",
to force it to listen on the IoT interface. Seems like something similar needs to happen here.

I added the Roomba parameters manually, same error, and it doesn't find the Roomba. Disabled discovery, still nothing. Roomba pings from the command line, so it's online and accessible. Also, when I open the Plugin Config, I get the orange bang next to the Save button that says "Config validation failed." Everything was done via HomebridgeUI, no manual editing of JSON.

Yup, ran into this today as well.

[afridorian]

Hey I'm having this issue as well. Running homebridge on a Raspberry Pi that is having no issues pinging the Roomba's IP and pulling the password/Blid. However, I'm getting the following errors:

`[26/06/2025, 23:51:00] [CloudflaredTunnel] Failed to connect roomba: WALL-E with error: No Roomba Found With Blid: ************************************

[26/06/2025, 23:51:00] [CloudflaredTunnel] This usually happens if the Roomba is not on the same network as Homebridge, or the Roomba is not reachable from the network`

Homebridge is on 192 network via eth0 and 10 network via wan0. Roomba is also on 10 network. Any ideas on how to fix?

[rubnogueira]

This should be solved with my last PR:
#187

Can you guys test it?

[jlg89]

Doesn't appear to be finding my manually-configured device. It's online according to the iRobot app. I don't see any "No Roomba found" errors, but it also doesn't seem to discover anything or create any accessories.

[rubnogueira]

@jlg89 Please test with the "discovery" on and without manually configurated devices. From what I know, it's only enabled in that situation. If it doesn't work, I can add here the small script that I made to debug.

[jlg89]

I just reenabled Discovery (rather, disabled Disable Discovery) and the plugin seems to have located the accessory, at least via the mothership. It's ignoring the manual config entry. So is it actually talking to the device on the local network, or just talking to the mothership, which then talks to the local device? This workaround is way better than nothing, and call me a choosy beggar, but having local control is a big plus.
