    • Any interest in Groovy programming?

      LibraSun

      I know this Forum has never focused much on SmartThings or Hubitat, thus not surprisingly I find virtually nothing here concerning the Groovy programming language or creating drivers/apps for those platforms.

      I'm curious: Is there any interest at all for co-authoring a "Definitive Guide to Coding Drivers & Apps for Hubitat" among our motley crew?

    • Super newbie here. Need help with lots of stuff

      A

      Hello guys. I'm currently building my own home and i want it to be kind of high tech and cool but i have actually never owned a smart device other than a smartphone and an old smart TV so i don't even know what exactly am i looking for. I will explain my idea and i am looking forward to somebody shining some light.

      Sooo - i was thinking about getting a WiFi controlled AC, TV, Washing machine, Dryer and smart switches for the lights. I suppose i need some kind of a assistant that connects to the wifi and can control all of these. Also i want an audio system - for the TV in the living room aaaand i also want to have 2 speakers in the bathroom which i have no idea where i would connect. I guees i need some kind of a receiver and amplifier for them to work correctly. But i also want that reciever to be hidden somewhere so it ahould be small and it also should be able to connect to the wifi i guess.
      So wgat exactly do i need so far. Would any wifi device connect to any assistant? Or am i lookng for particullar stuff... Will i be able for example to turn on my AC from outside the household for example when im at work? And can i also connect an alarm system of some type?

    • How to choose the right microcontroller/controller before starting the development of the SMART-house

      D

      Hi guys,

      I have started searching for some information about the microcontrollers/controllers with which I can develop my own controller and the SMART-house. It is needed for my research work. I am new to this, and it is hard for me to find the necessary information.

      I have found that such controllers as Arduino, Raspberry PI, ESP32, etc can be used.

      However, how can I find the model of the controller which can suit my requirements? They are the following:
      2-stage building with a garage (so it is +-400 sq.m.) with some number of SMART devices that are responsible for security (cameras, fire alarm, etc), temperature control, radiators, leakage control, opening/closing control, etc.

      I am interested in the hardware area at first.

      Any advices, links to the resources, researches, and articles with a similar topic will be really appreciated.

      PS: sorry for my not clear English (just in case)

      Thank you in advance.

    • Problem with LED Panel + Motion Sensor

      L

      Hello everyone, I am new here and also the conversion to smart home is new territory for me.

      I have a problem with an LED panel. This is coupled with a motion detector in my hallway.

      As soon as you enter the room it lights up, so far so good. However, it always lights up in a bright purple, even though my setting calls for gold.

      Now I select the lamp via the Hue app and drag my finger across the color palette, the panel changes to those colors and I have to keep selecting the preset hue.

      Can someone explain to me how I can keep this setting permanently without having to tediously reset?

      With kind regards

      Loorrd

    • HOW TO BALANCE LIGHT LEVELS AT A GIVEN SPOT

      LibraSun

      Having spent years as a professional portrait photographer, I came by many tricks of the trade involving readily available materials. One such trick is known as an "Oil Spot Photometer", which can help you equalize the brightness of two or more light sources.

      For simple setup instructions, visit:

      Oct 2, 2020 Oil Spot Photometer Oil Spot Photometer

      When an oil spot on a card is illuminated equally from both sides, it mysteriously disappears. This allows you to compare the brightness of the light sources on either side of the card.

      The implications for Home Automation, of course, is knowing the preset dim levels needed to balance a room's lighting, without guessing. Just bear in mind that dimmer levels and bulb output are rarely linear, so you may have to take photometer readings at various brightness levels to create a lookup table (for use in MSR, etc.).

    • Car integration

      rafale77

      I have been wondering what to post here so bear with me as I am just having a bit of fun given the fact that I haven't had much to fix, improve on or optimize for my home automation setup, I just added a scene today to make a TTS announcement to remind me to plug in my car when its level is low. Not really a necessity but since I have not been commuting anymore for a few months, I caught myself a few times wishing I had recharged my car the day before.

      This is what it looks like on openLuup:

      Screen Shot 2021-03-08 at 3.08.01 PM.png

      I reused a SiteSensor device which was polling my HomeAssistant integration for its lock status (Yes I can get openLuup to lock and unlock my car remotely) and made Home Assistant send the battery status.

      To do this, I added a rest service command on home assistant:

      rest_command: bmw_bat: url: "http://openLuupIP:3480/data_request?id=variableset&DeviceNum=26&serviceId=urn:micasaverde-com:serviceId:HaDevice1&Variable=BatteryLevel&Value={{states('sensor.i3_charging_level_hv')}}"

      Note the device number which will need to be the device you want to send the battery status to and the home assistant entity which you will have to replace with the one you want. Then I created an automation on home assistant to trigger this service whenever the entity state changes.
      Screen Shot 2021-03-08 at 3.20.36 PM.png Screen Shot 2021-03-08 at 3.20.46 PM.png

      After that I just simply created a scene on openLuup to watch the battery level variable and do whatever I need to do with it.

      This is an example of syncing entities in home-assistant to openLuup. I have a number of other similar integrations...

        I might have a need to modify some drivers for Hubitat, but can't commit to produce any guides

        Using MSR on Docker (Synology NAS), having InfluxDB, Grafana & Openhab, migrating from VeraPlus to Hubitat C-7

          I just installed VS Code and a few Groovy-related extensions. Definitely not past the n00b mark myself.

            Same here. Modified some Qubino drivers and made one to set associations, but that is it. Still relying on Openluup for most.

              I jumped in and did a new Venstar ColorTouch Thermostat driver for HE. I'm a Java guy from way back, but I'm not in love with Groovy (not even a little), and not impressed with their developer API. The HE docs weren't very helpful, either; it was mostly a process of discovery, trial, and error. Doing a better guide would probably ease that pain for many, but I think there are devs with more experience on that platform that would be better partners than me for that effort, and frankly, it's not the platform on which I'm choosing to base the bulk of my home automation anyway, and not where I would choose to spend a bunch more time.

              Author of Multi-system Reactor and Reactor, DelayLight, Switchboard, and about a dozen other plugins that run on Vera and openLuup.

                Something tells me you are in the majority with that sentiment. But no question that better documentation is sorely needed. I'm probably the worst person to nominate for the job, but heck, I wrote much of Vera's docs so I've at least got that pedigree, lol.
