When using an OR gate, only ONE or more conditions must be true for the output to be on. To summarize, with the AND gate, all inputs must be true for the output to be true. Conversely, if both switches are made (or no switches), then our output is false. If the North OR South pushbuttons are made, we get a true output. Needless to say, it might take some other logic to get this example to work the way you want, here is an example of the XOR. For example: We have 2 push buttons on both sides of the room to turn a light on. A real life example of this might be to limit a function if we have a stuck push button. With an XOR, the output is true only if ONE and ONLY one of the inputs are true. XOR (Exclusive OR) OperationĪlthough you don’t use the XOR much in home automation projects, there are some uses for it. Open the dashboard, you will see an empty list. Obviously, I’ve changed the operation of the node to OR.Īs you can see, if any one of the motion sensors are tripped (or both) then our output goes true. node-red v0.19 or above node-red-dashboard v2.10.0 (v2.15.4 or above would be ideal) Usage.
In this case, we would say: If North Motion Detector OR South motion detector is true, then energize the output. Again, it’s usually easier to put this into plain English before writing the logic. When ANY of the motion detectors are tripped, we want the output to go true. For example: We have two (or more) motion detectors. OR OperationĬonversely, the OR node sends a TRUE output when any of the inputs are true. If one of those conditions are false, then the result will be false. The configuration of the Boolean Logic node is as follows:Ĭoupled with our node layout, we can see the result. We’ll use a debug node to display the output. Here is an example of utilizing 2 inputs from a ControlLogix using the Eth-IP node. To rephrase it as an if… then… statement: If the Garage Door is up AND it’s Night time, then turn on the output. Because I don’t want my garage door to be up at night, I might send a true state to the garage door opener to shut the door. In other words, lets say we have the Garage Door Up Limit Switch and a Night Mode bit. executes the query against the database (Postgres 2 box) to check for alarms. When using an AND gate, both inputs must be high. It is implemented with the Node-Red tool, which works by execution flows. While it may be intuitive to some people what the purpose of the AND gate is, others struggle when using it with logic.

The Honeywell Tuxedo Touch and AlarmDecoder both have a http API so you can control them with anything that will send a URL. Tuxedo Touch will also work with Honeywell's Total Connect 2.0 App. The Tuxedo Touch and AlarmDecoder both have webservers built in to control the system remotely through a browser, preferably over VPN.
I also set up AlarmDecoder to send PushOver notifications on alarm events. UI (whats called Frontend UI) can render a UI for an Alarm Panel.
#NODE RED ALARM HOW TO#
Cams are able to be viewed on the Tuxedo Touch Controller as well. How to trigger a Node-RED flow from the Home Assistant UI. I set up AlarmDecoder with a custom notification for arm/disarm so the alarm system sends a URL to Blue Iris to switch profiles when the alarm is armed to start recording with indoor cams and another to move the indoor PTZ cams into position, then when disarmed it sends another PTZ preset so they point away at the celling and change back to the default profile to stop recording.
#NODE RED ALARM CODE#
It's often described as a low code solution, as a developer I like the option to apply code logic as well. Then for redundancy and more home automation options I run AlarmDecoder in Linux on a Raspberry Pi powered off DC from the alarm battery. When I dismiss a notification the alarm / timer should be deleted If they are deleted on the google device the notification should be removed Node-RED I use Node-RED for all my automations, I like the way it visualizes the flows. I use a Honeywell Vista 15P with the Honeywell Tuxedo Touch Smart Controller.
