***SONOFF - WiFi Wireless Smart Switch***

My DMX Stage Light Controller in testing last year

There shouldn't be any server needed unless updating settings. I have set the schedule via wifi, turned off my router, and tested they do what they were programmed to do several times. Never failed me. Handled daylight savings just fine and it will even automatically account for your time zone changing on the app. So for example. My lights turn on at 7am Mountain, when I was in Ohio for the holidays, it showed the "on" time as 9am Eastern. Can anyone link me to the problems? I feel like I have a good understanding of how these things work and it seems odd they wouldn't work on account of a sonoff server issue.

I have done a bit of reading and you are right. The timers are local so even if Wifi or Internet is disabled the relay will still turn on and off at its set times. The caveat is that it will only work if it has already got its time from the 'net as there is no RTC. This should not be an issue either really.

No freeze is an important improvement. What is this thing? It can change percentages indeed and it is wireless and expensive?

What is it, and what does it? The thing with the LCD display looks nice fabricated. I want to show this at the university.

reboard#1 is the board with the 2 rotary encoders. In the pictures is a prototype. On the reboard#1 are schmitt triggers and CD4013 D Flip-Flop‘s to make it easy to read the output from the rotary encoders.

You can choose in a setup menu if you want to use your fixture via your home netwerk, cloud based or as a webserver.

The display and camera work with the SPI and I2C protocol. The sensors work with the Onewire protocol. Because al that protocols used up almost all the pins on the ESP i used an MCP23017 port expander to read the input from the rotary encoders and to switch the 5 relais, the fans and the backlight of the display. The MCP23017 works with the I2C protocol.

The dimming is done by a PCA8695 PWM IC. It is 12 bit and has 16 ports. It works with the I2C protocol. I only use 2 ports for 2 hlg drivers.

The clock is a DS3231 that also works with the I2C protocol. A clock is nescesary If the WiFi signal drops.

The camera is send via WiFi to a home server (raspberry pi with a harddisk) or to the cloud. Very nice for high resolution time lapse video’s.

great work. Looking forward to seeing your light and how it integrates. Are you an electrical engineer or hobbyist? Everything looks well thought out and professional. Also, what are you programming the firmware with?

no it will not, see my former posts. 2 drivers on one timer, one went off, the other stayed on. all in the same time they had server problems in europe.

This is one of my DMX stage light controllers being tested on a dmx portable unit with dmx signals. The clicent is using a portable dmx master controller with very fast rise and fall times. The percentages on the lcd is the rate of intensity of the light.

My DMX controller keeps up with the fastest dmx masters out there. This is one of my stage lights under testing with the led disconnected to save power and sight. Each fixture has four Meanwell HLG-240H-C2100B drivers being driven with my cocntroller controlling intensity.

The routine is called fire, it simulates a fire with stage lighting, the most difficult to replicate. Client was testing unit as prior unit would freeze up when the lcd lost power so I provided separate power supply and now the unit flies like an eagle.

I also have a professional strip light controller with four channels for RGBW very few of those out there with dmx controls.

I have many of these controllers I design with Arduino and custom programming. They are called GrowGreen family of led controllers for horticulture, stages, and residential use. working on home automation as well.

Client chose the lcd they wanted to use and I modified the system to work with their lcd. I have a family of controllers for stage lighting. I also have a Github account under my real name as a programmer, engineer and architect.

thanks for noticing. please share with your class.

Yep I saw your post. I am referring to the TH16 and have not looked into the basic switches. The TH16s have local timers thats all I know.

Are you guys able to turn on a pump for 1 minute intervals every 2 hours for 12 hour's during lights on every day?

no, maximum of 8 timers, so only 4 waterings (4x on, 4x off) with the stock firmware. you would need to flash the sonoff with something like tasmota and use it in an home automation environment via MQTT

you could make it work with 2 stock sonoffs in parallel though

Check out my IG @bizfactory (also linked below). I have a Raspberry Pi that monitors/graphs temp and humidity and displays a live image (when the lights are on). Grow nerds are the best nerds!

Dear Bizfactory,
I hope this comment finds you well. For the first time since I heard of this social media, I went ahead and browsed your instagram page. Fascinating (your page. IG not so great)! Am I correct in saying your do a no till in a 2x2 tent? Would you be charitable enough to give some details or provide us with a link explaining your setup? I am on my 3rd ROLS grow and would love to delegate a bit more of the work to Mother Earth.

NoTillingly yours,
M

yo growers, heads up on something New GreenGene Utubed. Zigbee wifi controller. Timer, dimmer, set time ramp-up and ramp-down lights. Around $65 for the set-up, ( Hub and controller ) Works for B drivers only. Just happen to see this thread, and thought Id drop this here for anyone interested.

I have a 2x2 and a 3x3 (actually slightly bigger but 3x3 is easier). What are you curious about? Ya gotta ask specific questions. I don't know if you are curious about the raspberry pi set up, no till growing, sonoffs or what. Happy to answer any questions but I'm not gonna write up every single detail of my grow.

Looks great but the price kills it for me. I got 5 sonoffs for 25 bucks shipped and don't need any sort of hub.

Is anyone running more than 8 sonoffs? Wondering if it can be done.

Dear Bizfactory,
I am interested by everything but first could you let me know what light type/wattage & pot size you are using? I am not sure if it is the right place to ask these questions, so I extend my apologies to whomever considers I am burdening this thread.
Newbeeingly yours,

Unfortunately I don't know anything about flashing new firmware or setting up a home automation thing.

If 2 were used in parallel how would you stop the power from backfeeding the other while it's off? Would that ruin it?

i dont understand your question? if one sonoff's relay is off, while the second is on, how should that backfeed the first one?

I guess back feeding the open side of the relay that not energized wouldn't be a problem. I'm no electrical guru lol


Can the sonoff switches use inputs from the th10 and th16?

yes, you can do scenes that get triggered by sensor events

I have a Broadlink that can do just that.
It cost a little more, maybe about 12$
