Wait Until Node - Ignore unavailable/null/NaN?

[pistonhome]

Trying to use a wait until node in order to wait until the humidity has dropped in my bathroom. Is there a way to ignore unavailable/null/NaN values (in case the sensor is offline/unavailable). Currently, if unavailable, the node will wait the entire allotted time as it can't fulfill the request and then times out. I tried rigging up some JSONata code, but I am not sure it can be done currently in the wait until node.

For context, I am trying to wait until the humidity is less than 40%.

Not sure what you're looking to do when it is one of those values? Trigger right away?

Great question. In my specific instance, I would want it to trigger TRUE immediately, but in other instances I could see if one preferred it to time out FALSE immediately.

I would recommend using a current-state node before the wait-until node and checking there and then just skipping the wait-until node.

Yep, i figure that's the only way. Just checking if this happened to be built into wait until nodes.

Thanks again for your contribution zachow; the wait until node is one of my favorite ones. Especially because it is the only one that can evaluate attributes (as current state node cant).

[zachowj]

You can check against attributes in the current state node. It's just not as UI-friendly.
