We had a powerloss yesterday and now all my dashboards are gone. I managed to restore all flows from a backup file. But where does Node-Red store data thats Dashoboard related, names, sizes etc ---

That’s weird… I’ve rebooted my NAS several times without any problems. Did you install Node-red using Docker? In docker you can export the complete image for backup. Or you can export all nodes inside of Node-red in JSON format (Hamburger menu =\> Export =\> All nodes) ---

I have created an homey user for all members, but did not give them the app. And use smart present to switch the homey users home/away. Then also the cards last person left the house and first person to come home are functional. Homey presence is send to mqtt (i thought I saw that) ---

Awesome, I’ll look into that. How do you mean replace all flows of homey? And btw, what do you do under teh “security” tab with all the locks. Cna you really lock the bathroom from there/ :O. Cool if yes, hahah. expensive as well?those locks?.. ---

> How do you mean replace all flows of homey? With node red you can read en set devices trough MQTT. For example, turn the lights on when the light sensor gets below 20 lux. Almost everything you can create with flows, you can create with nodes in node red. You can create way more complicated structures if you want (which are not possible with flows). Going this route would make the Homey just a translator for every device to MQTT, and the node-red server the brains. I haven’t done this myself, I rather control my devices as directly as possible, but if I have a complicated task in the future, I might do this with node-red. > And btw, what do you do under teh “security” tab with all the locks. Cna you really lock the bathroom from there/ :O. Cool if yes, hahah. expensive as well?those locks?.. No, these are just window / door sensors. If I leave I can see all the open windows without physically need to go there to check. ---

> i’m unfortunately not talented enough for the manual / coding lines steps and will have to wait for a version for general audience Maybe the HomeyDash project will get a more widget style dashboard, but I don’t think node-red is going to get less complicated… although it’s not that complicated, if you managed to install the software on a server and go trough to the steps in my tutorial it shouldn’t be that hard. How is everyone’s MQTT memory usage? It seems to be way less than I started this project. The Client went from 38MB to 22 MB The Hub went from 35 to 23,8 MB (Don’t know about the Broker, I run this one on my NAS) Dont know why, maybe the Homey 3.0 update. ---

I have a question, probably I do something wrong, but can’t see whats wrong: If i toggle the switch from a lamp on the node-red dashboard, I see in MQTT Explorer that the topic is updated, but the lamp stay’s off. Like the MQTT client app in the Homey does not read that topic and/or react on it. How does mqtt client know which topic to look in? I understand that the hub only sends the current status to mqtt and node-red is used to read these topics and set the values, but I don’t see how mqtt client then looks in the right topic and act on that. What about LWT? Do I need to configure that in the MQTT client? And in the hub, should I enable that? And what topic paths should I use? My config is Homey with MQTT client and hub apps. MQTT and Node-Red on a Pi3, and topics from Hub are published to mqtt and updated (including on the node read dashbard, when status is changed in Homey. ---

Just use a simple Switch node, and change the on/of icon to a droplet or something. You can even change the on / off icon colour (see the locks in my dashboard) Enable “Switch shows the state of the input” and attach the sensor MQTT signal to it (you might need to change the boolean string to a real boolean value. See the first (tutorial) post how to do that with a function node.) I also have water alarms, I personally unhide a complete Group with a big warning if something like that happens. ![WaterAlarm](https://us1.discourse-cdn.com/flex025/uploads/athom/original/3X/9/d/9d97b9b2388624f0c003bdff383d6a4d8b507ff8.png) ---
