Ezlo Linux firmware - HTTP documentation preview


How do I make these API calls remotely? I.e. is there a vera domain name I can hit instead of the local IP?


I don’t believe Ezlo have this functionality currently.

Apparently you could do this in the past with the Vera Http API and their relay server, but they discontinued that service.

Personally I’ve only ever used http calls like these locally on my LAN.

I guess you could open the port number on your firewall and port forward, but I wouldnt recommend that unless you can add some extra security some how, like a static source IP address.

A VPN connection to your local LAN might be another option.

Hey cw-kid! Your CW’s IDIOT GUIDE has been very helpful, thank you for putting that together!

I found something that’s working right now, I’m just not confident that it’ll be supported long term since I can’t find any documentation on it… but here’s what I did:

  1. Following Python Script for Ezlo FW HTTP API Curl commands I saw we could get the Identity and IdentitySignature by doing a:
GET https://vera-us-oem-autha11.mios.com/autha/auth/username/{USER_NAME}?SHA1Password={SHA1_PASSWORD_FROM_SCRIPT}&PK_Oem=1&TokenVersion=2
  1. Using the Ezlo API Tool, and inspecting the requests with the Chrome DevTools, I noticed they were making this call (I’m not sure if this domain will always be around):
GET https://mms-proxy.vercel.app/device/device/device/{DEVICE_SN}
--header MMSAuth {Identity}
--header MMSAuthSig {IdentitySignature}

From the response we get a Server_Relay (e.g. wss://nma-server6-ui-cloud.ezlo.com:443) which I can connect to with a websocket and start communicating. The Chrome DevTools showed me what messages they’re sending to authenticate.

But without seeing any official documentation, I’m worried I’ll build something that will stop working one day because it’s not officially supported.

Good detective work. @Oleh is the man to ask this question too.


I did manage to use a Websocket client remotely as that is basically mimicking the Vera App access. However, I do not know if that applies to the http requests.

@Sorin, can you answer this?

Cheers Rene

I think this is still @Oleh. I’ll ping him privately.

Hi @reneboer, curently http requests are working on local mode only.

Hi @zAndy
Checking with the cloud team and will back to you asap.

@Oleh i’m trying to use the http api but i run in to some problems for some reason its not working.

i’m trying to run a scene with the following command:
but i get
Hmmm… can’t reach this page refused to connect.


in the api tool i have enabled offlineAnonymousAccess: true and offlineInsecureAccess: true, the id of the scene is 5ffda2f1124c353a415f679a

_id: “5ffda2f1124c353a415f679a”

enabled: true

house_modes: Array[4] [“1”,“2”,“3”,“4”]

is_group: false

name: “Test Scene”

parent_id: “5ffd9387124c3539f37741d1”

then: Array[1] [{“blockOptions”:{“method”:{“args”:{“abstractId”:“abstract”,“capability”:“capability”,“command”:“command”,“parameters”:“parameters”},“name”:“sendCloudAbstractCommand”}},“blockType”:“then”,“fields”:[{“name”:“abstract”,“type”:“string”,“value”:“6a4dfa60-54d3-11eb-b471-a3668ce75ba8”},{“name”:“command”,“type”:“string”,“value”:“send”},{“name”:“capability”,“type”:“string”,“value”:“text_command”},{“name”:“parameters”,“type”:“object”,“value”:{“text”:“play classical lullabies playlist on kid echo”}}]}]

user_notifications: Array[0] []

when: Array[0] []

what i’m missing?


192.168.xxx.xxx network is not a public network.
It’s a network provided by some local hub/router. So, no one outside this local network has access to addresses of this network. So, you need to make requests from the same network your hub is located in.
To check if you have access to that IP, please, open the terminal window and run the command:
If you’ll get the good ping like (my hub has a similar kind of address

PING ( 56(84) bytes of data.
64 bytes from icmp_seq=1 ttl=64 time=0.260 ms
64 bytes from icmp_seq=2 ttl=64 time=0.238 ms

So, if your computer is not in the same network, you will not be able to use local HTTP requests to your hub. If you get good ping results, you can ask your hub with curl console utility just like that (in bash for Ubuntu Linux):

hub.info.get with POST request:
curl --insecure “” -X POST --http1.1 --data-raw ‘{“method”: “hub.info.get”, "id: “auto”, “params”: {}}’

hub.info.get with GET request:
curl --insecure “” --http1.1

get broadcasts stream:
curl --insecure “” --http1.1

Hi @oleh yes i’m on a local network of course. the ping results is

miki@ubintu:~$ ping
PING ( 56(84) bytes of data.
64 bytes from icmp_seq=1 ttl=64 time=0.585 ms
64 bytes from icmp_seq=2 ttl=64 time=0.497 ms
64 bytes from icmp_seq=3 ttl=64 time=0.673 ms
64 bytes from icmp_seq=4 ttl=64 time=0.533 ms
64 bytes from icmp_seq=5 ttl=64 time=0.619 ms
64 bytes from icmp_seq=6 ttl=64 time=0.537 ms
64 bytes from icmp_seq=7 ttl=64 time=0.605 ms

the result of the curl command is:

miki@ubintu:~$ curl --insecure “” --http1.1
curl: (7) Failed to connect to port 17000: Connection refused

What version of the firmware on your hub (hub.info.get)
Can you fetch some logs from the device?
ssh root@ -n ‘tail -n500 -F /var/log/firmware/ha-uid.log’
Does it contain some errors?


I think the https request only work for the Edge hub and not the Atom. The latter is still to come.
