I am using nodered to create reports for usage od my ewelink/sonoff devices in my home.  
In my house I have majority light switches from Sonoff.  
I am using Node-res to listen to all changes in switcher and then I am streaming this data to Azure and than I amcreating reports with Power BI.  
Everything is working fine with up to 4 event listeners. When I add fifth and when I deploy it, randomly one of the five listeners is disconnected. Every time i force deploy another rnadomly selected event listener is disconnected.  
I was thinking that maybe there is limit for only up to 4 devices, but it makes no sense that this limit is so low.  
If anyone has any idea, please let me know. ![Capture](https://us1.discourse-cdn.com/flex026/uploads/nodered/original/3X/1/f/1f1f21ce97c89463db0b4a63f8908d54d7d69025.jpeg)

I think you will need to contact the author of the node to check .

This is a known issue,. As a work around you can sign up to another ewelink account and share all the devices to that account. That will get you another 4 listeners. Could you not use one listener for all, as you could filter in the function for the deviceID

Hello,  
I just tried with another account. So i create new credentials. For particular device I shared it with newly created accont, than in the node red created new listener, assign it new credentials, but i still get randomly different devices disconnected.  
Any idea?

That's odd, i have 12 ewellink device nodes running using 2 accounts, as limit is 6. All working for me.

AS i said before would it not be best to us just one listener, and use the following function block or a switch to route the message using the deviceid.

Hm, I don't get it, what can be the reason, but in my case, it doesn't matter, whether i use additional ewelin credentials, one of the seved devices is dicsonnected.  
I am looking to your flow, but to be honest, i don't understand it. Can you please zoom out.  
Every listener needs to have specific device id, therefore i don't understand how can I use only one listener for more devices.  
Thank you in advance!

hey E1cid,  
Thank you very much. I figured it out. I have one generic listener, withouth deviceId specified and than i am just using switch as you mentioned. Exactly what I needed. Thank you very much!
