what are the benefits in using sunset/dawn settings? besides lowering your DLI?
I think it should reduce the shock when switched on and imitate nature, but don't use it.
It's often used by aquarium guys but if it were so important to do the same with plants, we would see it a lot more often. So I do not think it's really useful.

It‘s a lovely feature I have to remember for the future! Actually I only have driver of the A version, and will use 2 of them to controll the light in flowering. So I can add some light during 60% of the day.

Before you make a build, have a look at aquarium controller like the HurricaneX controller from StevesLED.

Thanks for the hint! But actually too less time in life for more. I just need new timers, so I went with the sonoffs, because of the price and rf remote controll, which makes things really practical and safe for me, when I can shut down what I need, with just a key. I guess one day, I will learn how to use andruino and raspberry stuff, to customize control.

Thanks for your answers!

you can power the pro model with a 5v power supply and use that to control relay controlled outlets to get pwm style control with no pwm controller, but you only get on/off functionality no dimming. Can control four fixtures this way with only dc voltages. AC voltages would be at the relay controlled outlet.

Please tell me what I dont‘t get now... because when I use my 4CH (standard) I can controll up to 4 driver (on/off, timing). So the same you suggest now? Or not? Just way easier...

With a Sonoff Pro you can use either dc or ac control voltage.upload_2017-11-3_14-54-55.jpeg
Note the dc plug.

with dc voltage you can use 5v to control the outlet I showed you with any schedule you program on the 4 channel Pro just like the 4 channel model, except the PRO can turn the outlets on/off on schedule as you set it up. No ac to play with, just 5v dc with a wall wart 5v 1a. The relay controlled outlet manages the ac and the Sonoff manages the dc. No electrical experience needed and no messing with mains or ac voltages either. Just plug your fixture into the outlet and the Sonoff controls the on/off outlet just plug the outlet into the wall for power and plug 5v power supply into sonoff and use 22 gauge wire. connect comm on Sonoff to negative on outlet, and NO to positive on the outlet.

Yeah, i want to use the dc plug for fan controll.

Actually I have problems to follow you, just because I am missing the theroretical knowledge. When I understand you correct, you think it is dangerous to run the high ac voltage through the sonoff? But isn‘t it rated for 16a and 2200w? I thought I could use them as my old timer, just that I can connect everything directly, joint box and wago for the rest, so I have no more string chaos.

Why do you think it is an electrical experiment? Thought they are sold to work like this.

You misunderstand. I said if you lack electrical skills you can use it in various ways only working with dc voltage.
I use sonoffs with ac mains regular. Work fine that way. Was speaking towards using the pro with dc voltages 5v 10v 12v etc. For fan controls you can use a sonoff th16 with a temp/humidity sensor to turn fans on off based on temps.

With a single 4 channel Sonoff Pro you can make your own 4 channel wireless controller using the approach of relay controlled outlets, which sonoff recommends, with wireless connectivity. Four channels of wireless using a PRO with 5v power supply will make a great led controller much cheaper than most. Pro cost $22/ea relay cost $22/ea. program the scenes in the PRO and connect it with 5v to four outlets and you have an inexpensive wireless led controller that is eWelink capable anywhere in the world.

There are many ways to use these Sonoff's. One recommendation is to buy them from ITEAD directly for best customer support and lowest prices from here ->https://www.itead.cc/smart-home.html
they also have forums like here where you can get much information and ideas.

I am also working at reprogramming Sonoff's to work with Blynk as an app available for use by anyone via upgrading the firmware to Over The Air updates, connectivity, and control. maybe the grow control of he future right in front of our very eyes.

There are a few folks out there programming Sonoff's

Cargil ->https://tech.scargill.net/the-sonoff-4ch-pro/
captain-slow ->https://captain-slow.dk/2016/05/22/replacing-the-itead-sonoff-firmware/
arendst -> https://github.com/arendst/Sonoff-Tasmota

Lot's of good info out there to roll your own.

Step 1: Wire a Plug

Connect the live wire of the power plug to the live terminal of Sonoff TH.
Connect the neutral wire of the power plug to the neutral terminal of Sonoff TH.
If it’s a three pin plug, you need to connect the earth wire of it to the earth terminal of Sonoff TH.

Step 2: Connect the fan to Sonoff TH.

The way is the same as that of Step one.
Respectively connect the live, neutral or earth (if any) wire of the fan to the correct screw terminals of Sonoff TH respectively.

Step 3: Plug Sonoff sensor into Sonoff TH.

There are two Sonoff sensors, AM2301 and DS18B20. The former can measure temperature and humidity but it’s non-waterproof, while the latter is waterproof but it can only measure temperature.

So according to your need, select the right Sonoff sensor to plug to Sonoff TH. Here, I take AM2301 for example.
Step 5: Add Sonoff TH to E-WeLink

Hit the “Add device” button in this APP, and then press and hold the “Set” button of Sonoff TH for a few seconds. Select your WiFi account and enter the password. Name your device and lastly, click “ok”.

Step 6: Set the temperature boundary conditions

You’ll notice this APP can show you the real-time temperature value. Just click the device to set the temperature boundary conditions. Here, I make the temperature >= 35 ℃ asTurn On and <=30 ℃ as Turn Off.
Note that you have to keep your Sonoff TH power supply plugged in all the time.
Ok, now, a great fan with temperature control is done. When the temperature is higher than the value you set up, the fan will launch automatically. Also, you can turn on or turn off the fan through your phone via WiFi wherever you are. By the way, Sonoff TH has a timing function.

The options are nice, and I will use the aqua temprature sensor for monitoring and controlling the heat of the aquarium. My fans for air circulation will never be off, I just want to change from winter (7v) to summer (12v) mode, and have a on/off button (which would be the tablet in this case), because I don‘t use all 4 cabs all the time. Didn‘t found an easier way, getting rid of all the plugs the same time.

For my exhaust fan I would like to have a dimming like isawthelight mentioned controlled by the temprature sensor. Guess it‘s al possible, and because I already ordered a few parts of them, I just have play around with them now. Thanks for the hint to the forum! I will have a look into it.

Sonoff 4CH Pro is a 4 gang WiFi switch. It supports switching among 3 working modes: interlock/self-locking/inching(0.25-4s adjustable) mode. It integrates with a 433MHz RF receiver module, making it possible for the switch to be controlled by RF Remote. The Sonoff 4CH Pro smart switch is DIN Rail mounted.

Users can remotely turn on/off the connected lights/appliances by iOS/Android App eWeLink or 433MHz RF Remote. They can create 8 enabled single/repeat/countdown timers to automatically turn on/off at the specified time. The timers can run themselves even when network is unavailable. To let the devices be controlled by their family, they can simply share the devices to them and give specified timers permissions. They can even create some scenes or smart scenes to trigger ON/OFF the switch.

I had a box of these basic sonoff's, so I decided to put them, to work.

First , I started with my kitchen garden. worked fine got ride of timer and placed basic sonoff inline with L/N and let GND pass by. works great.

Second, Living Room garden has four MW drivers. I got a 4 channel unit, wired all four drivers into one unit rated for 3500 watts max. Each light turns on/off in sequence not all at once. schedule works great.

Lastly, I went to the rest of my gardens with the rest of my basic sonoff's and have everyone on a wireless schedule too now, I can access from anywhere, that includes Far Red using an lpc-60-1050 driver on schedule.
peace

Same here! My 4CH arrived, was easy installed, and it‘s working proper since that! Looking forward to the remaining order!

We have a few power outages every year, so what happens with the relay at 6:15 when power is back, but the timer was set for 6:00? Someone knows that? Or will I need to try it? (: can I put ON timers for 6, 7, 8, 9, ... o‘clock as saftey, or is there a problem with the relay?

I think time is stored internally so when you plug them in again they restore their schedule.
I usually setup and program prior to final install so I unplug a few times.

They restore for sure. My question is, when there is a timer for ON at 6:00, but I have a energy blackout from 5:00 - 7:00, will the lights go ON at 7:00? With my normal timers, also the digital ones, I define a time frame, where the light is working. But with the Sonoff‘s I can only define a time stamp to switch the lights on. Right? Fall asleep last night, but I guess I will be able to try and find out today!
