Run inject node on top of each hour

[John245]

The inject Node has no option to inject at top of any hour.

I have the following flow which is working when I inject:


However using the get hour function and filter option will not work (intention is to inject at top of each hour). The Get hour and filter nodes are given below:




Any idea how to get this working?

The Inject node will work on the hour if configured as shown below. I also included an export of the node if you want to import it instead.

There is an issue with the timeliness of the inject at least when Node-RED is installed on a Raspberry Pi. My tests have the inject occurring 8 seconds prior to the set interval and I am running on a R-Pi. I changed the minutes to 5 and it fired off at 2:19:52 and then at 2:24:52. I did make sure I deployed the flow at an odd point (such as 2:17) to make sure the test was correct. I also deployed a couple times at different intervals and the 8 seconds prior to was consistent.

Import:

[{"id":"3f35d274.99189e","type":"debug","z":"5a245aa1.510164","name":"","active":true,"tosidebar":true,"console":false,"tostatus":false,"complete":"true","targetType":"full","statusVal":"","statusType":"auto","x":680,"y":1840,"wires":[]},{"id":"4bc4cca2.df47e4","type":"inject","z":"5a245aa1.510164","name":"","props":[{"p":"payload"},{"p":"topic","vt":"str"}],"repeat":"","crontab":"0 0-23 * * *","once":false,"onceDelay":0.1,"topic":"","payload":"","payloadType":"date","x":480,"y":1880,"wires":[["3f35d274.99189e"]]}]

I deployed it, let's see what will happen. Running Node-RED on an Ubuntu server.

At least this solution is much simpler as mine in case I will get the required result.

It is working as expected. It consistently will run at the whole hour (or 1 second after the whole hour). For one reason for the level feature it happened 9 seconds after the whole hour.
