Error: Invalid URI

I think the issue is with your config file. I believe JSON strings can only be declared with double quotes as opposed to single quotes and almost every key/value pair must be wrapped with double quotes. I think there is an issue with the layout in general as well. If you want you can post your entire config with a couple things redacted and I can look over it if you would like? The bridge's mac-address username value as well as any device's messageID and sign values can be removed or edited. If you don't feel comfortable posting feel free to message me on twitter and we can figure something out. 🙂

Here's an example from my config that can hopefully help.

"accessories": [
    {
        "accessory": "Meross",
        "name": "Bedroom lamp",
        "deviceUrl": "http://192.168.101.xxx",
        "hardwareVersion": 1,
        "channel": 0,
        "messageId": "xxx",
        "timestamp": 1000000048,
        "sign": "xxx"
    }
]

OK - its all working now! - thanks!!

I hand edited the config to add the http and also to simplify it (it didn't work with the http added to my previous config); it looks like

"accessories": [
    {
        "accessory": "Meross",
        "name": "amp",
        "deviceUrl": "http://192.168.178.139",
        "hardwareVersion": 2,
        "channel": 0,
        "messageId": "17cfbf76eb100a721715de2c617f87fd",
        "timestamp": 1587218340,
        "sign": "XXXXXXXXXX"
    }
],

Can confirm it works!

Once you have updated the repo, I just need to

sudo npm install -g --homebridge-meross

to get back on the release version?

[arohl]

Done and can confirm works for me On 29 Apr 2020, at 4:50 am, Donavan Becker <[email protected]<mailto:[email protected]>> wrote: Just released Version 1.1.0<https://github.com/donavanbecker/homebridge-meross/releases/tag/v1.1.0>, if you want to give it a try. — You are receiving this because you were mentioned.

[donavanbecker]

@castorpollux285 are you using config-ui-x?

[arohl]

@donavanbecker Is it possible to reopen this? I have the meross plug "mss310" and get a similar error (although I got my parameters using https://github.com/bapirex/meross-api/). I did use config-ui-x.

Many thanks

@castorpollux285 @arohl

Could you both edit the deviceUrl in your config file to include a http:// header and see if that fixes the issue.

Ex. deviceUrl: 'http://192.168.178.139'

Be sure to restart your homebridge instance after making changes to your config.

[arohl]

Will do first thing tomorrow- it’s quite late in Perth :-)

However I did manage to get Charles on my iPhone and the POST seems very simple for this model of smart plug

{
"payload": {
"togglex": {
"onoff": 1,
"channel": 0
}
},
"header": {

"payloadVersion": 1
}
}

[dylanfrankcom]

Thanks for posting the payload. It will help later if the changes in your config don't. Please report back if it works!

Got the same error

I think its much harder than this unfortunately. I have been playing around with this plug and can now send it data but I always get an error.

{
header: {
messageId: 'c3222c7d2b9163fe2968f06c45338a9f',
namespace: 'Appliance.Control.ToggleX',
method: 'ERROR',
payloadVersion: 1,
from: '/appliance/19090313123344251h1448e1e900e715/publish',
timestamp: 1587132239,
timestampMs: 245,
sign: '7c8b932061c9cea12444284cc7d2626c'
},
payload: { error: { code: 5001, detail: 'sign error' } }

When I look at what is being sent from the Meross App to the plug, the sign changes everytime so I am guessing that they have improved their security and until I find out how the sign is generated, I am out of luck :-(

[dylanfrankcom]

You’re right! The sign does change with every request sent through the Meross app, however a unique sign is not required with every new payload sent. The sign is able to be reused and is why it is included in the config file. I share the same messageID, sign, and time stamp between four plugs and two different hardware revisions.

As for the security aspect, it could be that the messageID, sign, and time stamp are associated with each other and are used to form some sort of authentication on the server. I really have no idea though. They might have to be taken from the same payload to work correctly. You could try replacing the values in your config with fresh ones from a new payload.

So far, this is expected behaviour and happens on all Meross devices. This also means there is still hope and I believe your device should be able to work.

[arohl]

OK

SO here is my config (copy and pasted from web gui)

{
"bridge": {
"name": "Homebridge A578",
"username": "0E:35:C2:82:A5:78",
"port": 51901,
"pin": "XXXXXXXXX"
},
"accessories": [
{
"accessory": "CmdTriggerSwitch",
"name": "amp",
"stateful": true,
"onCmd": "/Users/andrew/src/MSS310/start_amp.sh",
"offCmd": "/Users/andrew/src/MSS310/stop_amp.sh"
},
{
"name": "Meross",
"accessories": [
{
"name": "amp2",
"deviceUrl": "192.167.178.139",
"hardwareVersion": 2,
"channel": 0,
"messageId": "17cfbf76eb100a721715de2c617f87fd",
"timestamp": 1587218340,
"sign": "XXXXXXXXX"
}
],
"accessory": "Meross"
}
],
"platforms": [
{
"name": "Config",
"port": 8581,
"platform": "config"
}
]
}

[arohl]

Note that I have got something working using CmdTriggerSwitch - it calls a shell script which in turn uses a python library I found BUT this does it via talking to the meross cloud so has a lot of latency

[arohl]

Errors still like:

[donavanbecker]

@arohl Your device url still doesn’t have http:// in front of it. Also I need to update the config.schema to match that. Sorry!

[dylanfrankcom]

Fantastic! Was about to send you the exact same thing. Enjoy! 🙂

[donavanbecker]

@arohl would you be willing to test a change that I just made to the beta branch?

[arohl]

@arohl would you be willing to test a change that I just made to the beta branch?

Sure - but you will have to give me some basic instructions on how to install beta branch

[donavanbecker]

thanks,

from terminal install beta using this command:

sudo npm install -g --unsafe-perm homebridge-meross@beta

Then in your config schema, change the Device URL to just be an IP address. without the http:// in front of it. and let me know if you are still able to control your device?

Let me know if you need help installing it.

[donavanbecker]

with @latest at the end just to make sure it pulls the latest from npm.

[donavanbecker]

Thanks, for doing that!

[donavanbecker]

Just released Version 1.1.0, if you want to give it a try.
