How does os.execute curl compare to the OpenURL command in speed?
Edit: Should've just tested it. It's much faster. Script below updated.

This is my current script for driving my ESPEasy lights, including a way to simulate white on RGB-only strips. It also uses a curve to get higher resolution at the lower end, where the brightness changes are more noticeable.

Code: Select all

local lights = {
  ['Stuereol Spots'] = {ip = '192.168.33.61', pin = '14', rgb = false},
  ['Stuereol Skab'] = {ip = '192.168.33.61', pin = '4', rgb = false},
  ['Vitrineskab'] = {ip = '192.168.33.62', pin = '13', rgb = false},
  ['Kontorreol'] = {ip = '192.168.33.64', pin = '13', rgb = false},
  ['Skrivebord'] = {ip = '192.168.33.67', pin = '14', rgb = false},
  ['Sengelys'] = {ip = '192.168.33.66', pin = '14', rgb = false},
  ['Kontorhylde W'] = {ip = '192.168.33.67', red = '15', grn = '13', blu = '12', rgb = true},
  ['Stuereol W'] = {ip = '192.168.33.61', red = '15', grn = '13', blu = '12', rgb = true},
  ['Seng W'] = {ip = '192.168.33.66', red = '15', grn = '13', blu = '12', rgb = true}
}

function setlight (ip, pin, dvalue)
    os.execute("curl 'http://" .. ip.. "/control?cmd=PWM,".. pin .."," .. tostring(dvalue) .. ",128'")
end

commandArray = {}

for deviceName,deviceValue in pairs(devicechanged) do
    if (lights[deviceName]) then
        if (deviceValue == 'Off') then
            dvalue = 0
        elseif (deviceValue == 'On') then
            dvalue = 1024
        else
            inputValue = tonumber(otherdevices_svalues[deviceName])
            
            curve = 1.5848931924611
            normalizedCurVal  =  (inputValue - 1.0) / 99.0
            rangedValue =  (math.pow(normalizedCurVal, curve) * 1023.0) + 1.0
            
            dvalue = math.ceil(rangedValue)

            setlight(lights[deviceName]["ip"], lights[deviceName]["blu"], dvalue)
        else
            setlight(lights[deviceName]["ip"], lights[deviceName]["pin"], dvalue)
        end
    end
end

humz keep getting a error in domotiz when I try this one

[string "local lights = { ..."]:12: bad argument #1 to 'pairs' (table expected, got nil)
cant realy figure out why

Did you create it as a device-type script? Otherwise, the deviceschanged table is empty.

Oh, and there's a trick to get the full 1-100 steps on a dummy dimmer switch (Normally it'll round it to something like only 12 steps).
1. Create a dummy Selector switch.
2. Edit it and make sure everything is as you want it (Due to a bug, you can't edit it later*).
3. Set the switch type to dimmer.

Now the dummy switch will have the full 100 steps available.

* Unless you use your browser's debugging tool, to change the switch type to "Dimmer" in the edit link.

yea that was my mistake I did not add it as a device script
managed to find that adding it as a selector first and then changing it to a dimmer fixed the issue that it wont go tom100 % brightness

Crap... Even with the FTDi I receive an error

Uploading 416064 bytes from C:\Users\Remco\AppData\Local\Temp\arduino_build_539286/ESPEasy.ino.bin to flash at 0x00000000
................................................................................ [ 19% ]
.......................Er is een fout opgetreden bij het uploaden van de schets

I have tried many settings, but all the time the same error...
How the h*ll did you upload the ESPeasy firmware...

ledfreak3d · Post by **ledfreak3d** » Friday 25 November 2016 22:04

what settings did you use in the Arduino ide to compile and upload
and whats the size if your esp's flash ?

How can I check the size of the h801's flash?
I will make a screenshot this evening...

My settings are the same as the post from ledfreak3d except that my Flash Mode is "DIO" - no idea why though, but it works! My baud rate is 115200, not had any problems with any of my three H801s ...

My H801 flash looks to be a 25Q80 - I think all mine are the same so these settings should be ok for you too.

And ESPEasy reports .. Flash Size: 1024 kB

I have tried allmost all flash sizes... none is working.
I even tried to upload a small sketch to determine the size, but that also does not work...

I have connected 4 wires to my ftdi, (3,3 gnd tx/rx) and shorted J3 on the 801..

Tried with the same settings, no go. 115200 baud is not working as well. It needs 9600....

That's strange, I have had no issues at all. A couple of points to check - don't feed the H801 off the FTDI as there may not be enough current to reliably flash. My H801 header has TX and RX swapped - so you need to join TX to TX and RX to RX (and not swapped as you'd expect). You've probably already found this though!

Tried everything... but with an external power supply he won't upload at all. He can't connect.

Ok, I've not read your previous posts so apologies if you've already tried:-

1) flash original firmware using esptool

2) flash ESPEasy using esptool

3) a different USB --> serial unit

do you get the same errors?

deennoo · Post by **deennoo** » Saturday 26 November 2016 19:04

With external power : don't forget to join gnd to your programmer

Reley · Post by **Reley** » Monday 28 November 2016 14:57

With external power and ground connected it gives another error:

Code: Select all

warning: espcomm_sync failed
error: espcomm_open failed
error: espcomm_upload_mem failed
error: espcomm_upload_mem failed

[/s]

Working!
Don't know how, but its working now!

Now trying to create some nice hardware in domoticz...

Hi all,
Apologies for resurrecting an old thread, and being somewhat off-topic for Domotocz, but this does seem to be the centre of knowledge on this subject...

I have a couple of H801s connected to RGB strings. Everything works fine (LEDs work, I can control both H801s from my phone) except that I can't connect to either of them from my PC.

When I attempt to connect to UDP port 30977 on an H801, I get a "Connection Refused" error message. I'm working in Java on Linux... the code works fine for connecting to other WiFi devices. Has anyone encountered anything like this with H801s? And have a solution?

Thanks

Frank

Is this using the original firmware? I couldn't even get it to work reliably using the app - so probably won't be of much help, but will try!

If anyone wants to use the original firmware and control programmatically:

After having "Linked" the device using the Android app https://drive.google.com/open?id=0B1gzq ... ERBUndCU28 Default password 88888888

I was able to send commands via UPD from shell using https://nmap.org/ncat/

Code: Select all

echo fbeb00ff00000096509900 | xxd -r -p | ncat -4u -p 30978 192.168.1.255 30977

and from Python

Code: Select all

from socket import *
import binascii

cs = socket(AF_INET, SOCK_DGRAM)
cs.setsockopt(SOL_SOCKET, SO_REUSEADDR, 1)
cs.setsockopt(SOL_SOCKET, SO_BROADCAST, 1)
cs.sendto(binascii.unhexlify('fbebffe200000096509900'), ('192.168.1.255', 30977))

Hi guys,
Sorry, to be dumbo, but I dont have any experience with lua scripts.
I have h801 flashed on espeasy with RGB milight plugin and using applamp, colours works great but I would like to simulate white as well.

Could you please advise how to amend script for my ip device 192.168.0.106 and add to Applamp group one dimmer?

Thanks

Sorry for annoying
Vojta

actualy with above script you don't need to use the milight plugin
it will just dim using the build in pwm dimmer function.
