Node-red-staircase-timer

A Node-RED staircase type timer, turns on output for a specified time when triggered by an input with payload specified. can be disabled by light level (use a lux sensor for input f.ex.) and also overall disable until it's enabled again

Install

Either use the palette manager in Node-RED to install the plugin, or use a terminal to install directly in your local installation of Node-RED:

npm install @tbowmo/node-red-staircase-timer

Once installed, restart your node-red server, and you will have a set of new nodes available in your palette under timers.

Setup

Set the minimum light level, if used (remember to add a flow that can send a message with the light_level property), and configure the on/off messages to match your desired behavior.

If Restart timeout on new trigger is checked (default), the timer will restart each time the input is triggered by a truthy payload. Note that if the output has already emitted an onMsg, a new onMsg will not be emitted in this case.

If unchecked, successive triggers will not restart the timeout.

Output

The node has a single output, which provides a standard node-red object:

{
    payload: object, string, number // as setup in the node
    topic: string // (as setup in the node)
}

Input

If payload is present (not undefined) the output will be triggered, unless the node is either disabled or the light level is above the set threshold

Optional properties on input message

| property | type | description |----------|---------|-------------------------------- | disable | boolean | If set to true, then the node is disabled. If the timer is actively running, then the current timeout is handled as usual. | ligt_sensor | number | This is used to inform the node of the current light level. If the light level is above the set threshold, then the timer will be disabled
