@strawberry-3.141 That worked like charm! Spot on. Thank you! Just have to remember for long timers, the following clients need to wait for the first to timeout, before getting any data.

@E3V3A you can store the data in a variable in the node helper, every time someone connects and your start flag is already set you just send him the data from your variable

@strawberry-3.141 Great idea! Do you have any code examples for doing this? (I’m still a JS dummy.)
