FYI. Cool lil relay box for diy.

I saw this posted in another thread about a week ago, did you post it? Don't think so. Anyways, there was something about it that didn't fit what I was looking for (at that moment), I think it's limited to 120V, that might've been it.

Cool gadget though, I'd like to play with one. Maybe I'll check some of those videos out, thanks.

I may have posted it a month or so ago.

Kinda unique device that any grower might have a use for.

I don't know. My brain is hurting though. If I could say "fuck it for now" and put it off for a bit I would. But I need some kind of solution or other fairly quickly, haha.

Anecdote: I used to own a cheap, temp-humid-photocell-cycle timer(useless though) controller. I never used it. I was 'stupid' (function wise). I opened it up once, after, just from curiosity. It was basically an empty plastic box...lol. 2 or 3 relays in there I guess. Enough empty space for a PC grow in that stupid box. Hah.

This is cool: https://www.hydroponics.net/learn/grow-light-controller.php
There's nothing worse than spending time researching a diy for something, getting the parts together, etc etc. and then you barely save any money - or the functionality is lacking compared to the "real deal" or "retail" product.
Sweet link for the relay box there.
This is how my box is setup. Program station gets telephone cable to controller. And then I have a 12V 1a adapter. That triggers the relay which controls the 220V lines. Obvi I am just showing my layout there there's no 220V lines into the relays yet.

Cool man. Thanks for sharing a picture.

Question; why'd you go with a 12v coil relay, and a 12v adapter with the trolmaster device module? When, I guess, you could have just used a 120v coil relay, and triggered that with the program station via a standard 120v ac power cord to the relay (deleting the need for the 12v adapter)?

That's DIN rail you're using in there, is it? Cool.

I'm using a Raspberry Pi running an open sourced home automation software called Home Assistant (HASS).

Its super customizable and works with tons of different IOT devices. I use a combo of smart sensors and smart plugs. It controls lights, humidifier, dehumidifier and my mini split. It also calculates VPD for me in real time and has a video feed set up. You can use different sensors to trigger different devices. For instance, right now I'm trying to save power by not running my dehumidifier so I'm running an exhaust fan that triggers on and off based on the RH in the room. Once I flip and seal up and run CO2 I will switch my dehumidifier back on. I can control and monitor my grow from any device with an internet connection and a web browser. Home Assistant is versatile enough that I will be able to add an automated watering set up and eventually have it automix my nutes. Also going to add CO2 monitoring and control. Here is a pic of my dashboard. So far I've spent maybe $200 on everything. Learning curve was a bit steep but I'm finally getting comfortable with everything and its paid off.

Beautiful. HASS looked like the best option to me too when I saw LEDgardeners youtube vids on it. But I didn't know where to start, and just how complicated everything would be. Node Red, whatever else, yea, I wish I knew how to do that stuff now - I wish I'd put aside some time to try.
I have an arduino kit sitting in the box.

I could have used a 120V triggered relay. But you will find a lot of relays are 5V or 12v trigger commonly. And for me that's also good in a way dealing with lower voltage. One less high voltage connection to make. Very high amperage rating and good price considering the rating. The relay units fel heavy and robust. Already had the 12V adapter (got lots from old electronics). So I picked 12v because it was cheap. Trolmaster unit doesn't know or care about the difference.

ya mounted to din rail. Also the Trolmaster controller can mount to din rail as well.

wow I'd love to run some extra CO2 and humidity sensors around the room to confirm a good distribution no had no idea you could hook up all that stuff I just thought basic temp etc.

there’s a pretty extensive community of home developers that have made some cool additions. It’s a bit overwhelming to start. I originally bought a pi to run my home automations on something called homebridge. Learning about that led me to HASS. I installed it initially and gave up cause it was too complicated. Once I got my home automation dialed in, I turned my focus to the growroom and gave HASS another look. I’m by no means a computer expert but I’ve tinkered forever. I eventually started to figure it out. Just have to jump in head first!

Should be pretty easy to do. I’m using a thermometer/hygrometer I got on Amazon. I intend to build my own co2 sensor using a node mcu and a cheap standalone co2 sensor.

What a fitting acronym, Hass = Hash in my native tounge.

Great thread btw, lot's of great info to help out people, good looking out.

That would be cool. I wonder what the cost would be on something like that; how cheap a decent/quality unit could be put together for. Too bad a par meter couldn't be easily, affordably made. I'm dying for one, haha.

CO2 meter should be less than $50 in parts. Par sensor can be had for about $100 and probably run off the same Node MCU board as the CO2 meter. I'm gonna try and build a combo sensor in the coming weeks/months. I'll be sure to post my progress.

That'd be really cool, man. I'll keep an eye out for it. Maybe do a bit of looking into it if I can.
I have seen some "diy" type efforts at par meters, but they're... not what I'm looking for.

Right on, dude.

Don't know if you've seen Pulse One/Pulse Pro meters but I am aiming to make my own Pulse PRO. The Pulse has an awesome app that goes along with the hardware. I'm by no means a developer but I should be able to build something that can collect the data I'm after. From there I will make it work somehow with Home Assistant

Update,

I've been very disappointed at many points in time during my experience with trolmaster hydro-x. Planned/purposeful inadequacy to perfection is how I'd describe it, overall. It's not a piece of shit, but it's so obviously designed to not do what it should (and COULD) obviously be able to do - so that they can sell multiple other parts and products (aqua-x), that every time I want to do the most simple thing, I call it a fuckin' piece of shit.

I'm one notch above saying I absolutely hate it.

If I can get either something else pre-built that's actually capable, or get into something "diy" like raspi and mycodo - or HASS, I will, and I'll try and sell trolmaster. Pisses me off each time I deal with it.

:D

FWIW - Down in the basement of this place, Technology/Science, I posted my control system under the title "Get your Geek on and control your grow room with Arduino!" I thought you might want to take a look. I've been away from it for a while waiting for the laws in my zone to catch up, but now that they have, I am returning. Good luck with what ever system you come up with, I'll follow along.

Hey, thanks for the input, and the link to your thread there in "the basement" (didn't know about that area). I'm gonna have a look at it. I do remember oldmeduser mentioning he wanted to get into some arduino stuff a while ago.
