![]() either the light will turn on – temporarily overwriting the normal timed sequence, or, Alexa will respond with “I’m sorry I can’t find a device called shit green timer”. Saying “Alexa, turn shed green light on” will result in one of two things. Give the node a name you will use by voice, like “shed green light” and plug it into bigtimer, which, here, is controlling the light via MQTT. In a couple of cases, office and house heat, things work another way and I keep the current manual heat offset (which gets reset on every change of program) in global variables – in this case alexa-local simply updates the local variables in those orange function nodes.īy and large however the nodes feed straight into bigtimer – could not be easier. On the left the dark cyan node-red-contrib-alexa local nodes, on the right the lime green node-red-contrib-bigtimer nodes. Here is a tiny, tiny part of my home control setup. So – assuming you are using Node-Red and big-timer and can or have installed alexa-local – it is all this simple. Accordingly I’ve added that node to “the script”. ![]() Hence last night I took the plunge and stripped out Ha-Bridge and inserted alexa-local… and it is working a TREAT. Well, some time ago when messing around looking for alternatives to Ha-Bridge, I tested node-red-contrib-alexa-local and it had all sorts of issues – but now I check again they’ve all gone! It truly is lovely though as it stands it can’t handle colour control directly (but then neither does Ha-Bridge) – it will handle numbers from 0 to 100 so you could use your imagination… Some time ago I added manual override controls for this node and I’ve usually had Ha-Bridge send an MQTT command which is then picked up by Node-Red and injected into the timer. It is important that the light then goes back into auto timing mode the next day and doesn’t just stay off permanently.Īs developer of Big Timer (node-red-contrib-bigtimer) you’d expect me to make big use of this Node-Red node – and I do – dozens of them. ![]() I have an early night and decide to turn off the light manually. For example – a night-light outside might be on a timer from dusk until midnight. The reason I need manual input and timers connected, is to turn things off automatically if I forget. In reality I’ve always had it return commands to Node-Red – because many of my controlled items are on timers and I need the two put together. So for beginners, HA-Bridge is a piece of software (a very nice piece of software) that runs on for example a Raspberry Pi, who’s job (in my case) is to talk to Amazon’s Alexa and send off MQTT commands to control things. I’ve recently updated my setup at home, finally doing away with HA-Bridge and I thought you might like to see this simple setup.
