Hello all,
Today I noticed my NR was restarting almost every 3 minutes.
The crash/restart was caused by an uncaught exception on timeout of the ping sent every 30s.
19 Apr 18:03:21 - [red] Uncaught Exception:
19 Apr 18:03:21 - [error] Error: Can't send data because WebSocket is not opened.
at exports.throwIf (/x/.node-red/node_modules/websocket-as-promised/src/utils.js:4:11)
at WebSocketAsPromised.send (/x/.node-red/node_modules/websocket-as-promised/src/index.js:248:5)
at Timeout._onTimeout (/x/.node-red/node_modules/ewelink-api/src/mixins/openWebSocket.js:39:17)
at listOnTimeout (node:internal/timers:559:17)
at processTimers (node:internal/timers:502:7)
After digging a bit, noticed the connection was getting closed on the server side.
Fiddling with the heartbeat timer didn't help (tried with 10s).
So, i fixed/patched it by catching the exception and restarting the connection.
Offending original code, ewelink-api/src/mixins/openWebSocket.js

Patched code:
This seems to have fixed it for me. Every now and then the connection drops,
and at HB timeout the connection is re-established.
Hope this helps.
