WAF in jeopardy today

[dbemowsk]

UPDATE: So the Vera plugin that I modified to work with my sonoffs will show the status (online/offline) next to the switch controls on my Vera device list. This is done by the plugin using a ping signal to it's web address.

All of my Sonoff devices showed offline. When I tried to access the web pages of them, the browser couldn't connect, which was no surprise. One of them controls a tabletop lamp in my living room which I just have the controller spliced into a 2 prong extension cord. I reset that one a couple times and it came to life. Most of the other ones are mounted in the ceiling light/fan housing with no easy way to reset power. I ended up cycling the circuit breakers at the electric panel and was able to get all of them back online.

The power outage that killed them was a split second power outage. My wife and I were watching a movie on our Roku box and when it happened, the Roku box reset, but the TV did not shut off, which told me that it was just a quick flash. If that's all it takes to flake out a sonoff basic, all the more reason for me to lean towards switching to MySensors controllers for those. In all the times my MySensors switches and other devices have gone through power outages, even the brief ones like the other day, they have not skipped a beat when the power has come back on. Don't get me wrong, I still like the sonoff devices, I am just looking for the kind of reliability that doesn't put the WAF of my automation system into question.

One other reason I'd like to switch to a MySensors based solution is that I bought a new batch of 5 Sonoff Basics, only to find that they changed the design of the board. The one on the right in the two images is the old version, and the left is the new updated version.

The old version was based off of the ESP8266 controller like the NodeMCU devices. The new ones are ESP8285 based. The firmware that I use on my Sonoff devices is the ESPEasy firmware. My Vera plugin, which is a modified version of the "HTTP Switch (WiFi Switch)" plugin. My ESP8266 based sonoff devices were easily programmed using the Arduino IDE selecting ESP8266 with 64M No SPIFFS. Even after selecting ESP8285 and trying multiple SPIFFS settings, I cannot get them to flash. The ESPEasy website claims that the 8285 is supported, but they don't seem to show a way of flashing them that works. I have read a number of forum posts from various places that say they are difficult to program, with no one having a clear cut set of instructions to program them. Another reason to go the MySensors route.

@dbemowsk
I have 12 of these new and working without any problems.
There is a missing gpio14 pin, where I connected the DS18B20, but I used the RX pin instead.
PCB design is more solid to me - you can even see the power fuse.
ESPeasy flashing without problem using esptool.
My way to program new Sonoffs:

To check comunication:
esptool.py --port /dev/ttyUSB0 flash_id

Erase flash:
esptool.py --port /dev/ttyUSB0 erase_flash

Program ESPeasy bin:
esptool.py --port /dev/ttyUSB0 --baud 115200 write_flash 0x00000 ESP_Easy_v2.0-20180322_normal_ESP8285_1024.bin

@kimot Do you have a copy of your ESP_Easy bin file? It would be nice to program these and use them, it's just been a big struggle trying to find out how to do it. The earlier ones I got were ESP8266 based and flashed really easy with the arduino IDE. I am assuming you are hooking it up with the standard gnd-gnd, tx-rx, rx-tx and 3.3v-3.3v, correct?

@dbemowsk
It is from here:
https://github.com/letscontrolit/ESPEasy/releases/tag/v2.0-20180322

I connect it like you wrote.

[dbemowsk]

@kimot Thanks, I will try flashing them tonight.

[dbemowsk]

@kimot So I don't do a lot with python, and when I try to use a command similar to what you posted I get errors. So here is some background on the file structure that I have. I downloaded the ESPEasy_v2.0-20180322.zip file and unpacked it to a folder. That contained a source folder, the .bin files and a set of windows esp flash tools. I noticed that it didn't include the esptool.py python scripts, so I downloaded the source code zip file and unpacked the test folder into the same folder as the .bin files, since that looked like it had the necessary python scripts. So now I have a source and test folder, the .bin files and the windows executables. I navigated a terminal window into the test folder and ran this:

./esptool.py --port /dev/ttyUSB0 --baud 115200 write_flash 0x00000 ../ESP_Easy_v2.0-20180322_normal_ESP8285_1024.bin

This is the errors that I got when I ran it.

[dbemowsk@phpwebscripting test]$ ./esptool.py --port /dev/ttyUSB0 --baud 115200 write_flash 0x00000 ../ESP_Easy_v2.0-20180322_normal_ESP8285_1024.bin

I must be missing something, but I cannot figure out what it is.

EDIT: if it matters, I am running Fedora 28 linux.

@dbemowsk

You must install esptool:
https://diyprojects.io/esp-easy-flash-firmware-esptool-py-esp8266/
or
https://github.com/arendst/Sonoff-Tasmota/wiki/Esptool#esptool-executable-windows--linux

Attention, there are some dependencies...

Then normally go to folder where .bin file is placed and run command:

esptool.py --port /dev/ttyUSB0 --baud 115200 write_flash 0x00000 ESP_Easy_v2.0-20180322_normal_ESP8285_1024.bin

or

python esptool.py .........................

not ./esptool.py

But I suggest first try :

esptool.py --port /dev/ttyUSB0 flash_id

To check if every is OK ( port, etc )

@kimot I had already tried that through dnf prior to running that, but I did it again.

[root@phpwebscripting test]# sudo dnf install esptool

I know WAF is not a joking matter, but I immediately heard Greg Kihn sing, " my WAf's in jeopardy, baby".

[dbemowsk]

@wallyllama YES.....Drop the mic.

[dbemowsk]

@kimot So I'm a bit confused. I ran this:

pip install esptool

and then got this:

[root@phpwebscripting test]# esptool.py --port /dev/ttyUSB0 --baud 115200 write_flash 0x00000 ../ESP_Easy_v2.0-20180322_normal_ESP8285_1024.bin

So it worked. BUT, I connected a second one and tried running it again and got this:

[root@phpwebscripting test]# esptool.py --port /dev/ttyUSB0 --baud 115200 write_flash 0x00000 ../ESP_Easy_v2.0-20180322_normal_ESP8285_1024.bin

I ended up getting them all programmed, but I had to unplug and plug in the serial adapter a few times to reset it. It had even reset the device to /dev/ttyUSB1 for a couple of them. STRANGE...

Thanks for the help.

[kimot]

@dbemowsk
Yes, sometimes it got USB1 instead of USB0.
You can create fix symlink for your USBtoSerial adapter and then write for example ttySonoff and allways will be right.

[dbemowsk]

@kimot The main thing is that I got them flashed. I still have yet to figure out the new firmware and test them, but I am confident I can get them to work.

Thanks again.
