First of all I want to Thank you for your feedback! "Too expensive" comparing to what? Cheap China Boards available on Ebay and sold under the "sell-and-forget-about" strategy? It's a Apples vs. Oranges comparation. Proper testing, support, software examples and tutorials, all c...

Hello, as i don't have a FSS12 at hand for testing i have to guess some things. Please be aware that I do some practical prophecy here. So from the datasheet of the FSS12 i guess the internal circuit might be as in this pic: Counter-FSS12.jpg It might be possible to attach an opto coupler here but i...

Shardan

Hello, without seeing the set in real it's a bit of prophecy but I'll try to help out a bit. i assume there might be two problems leading to that issue. The first and most widespread one ist the power supply. First, if you use cheap "wall plug" power suplies - do yourself a favour and dump...

Due to my experiences the reset pin on the ESP-01 is a bit sensitive with all versions.
I used another way that worked much better for me:
- disconnect power (3,3V)
- connect GPIO0 to ground
- start flashing in the programme software
- power up the ESP-01

It definitely would be nice to have this in ESPEasy.

It's not only the Sonoff DUAL that has this additional chip, some other Sonoffs have it too.

You may use the Arduino ESP and compile a .bin File for the 8255-chip. In general it is an ESP8266 with internal 1024 kbyte memory so set the compiling parameters accordingly (Board type ESP-8255, memsize etc). Maybe this thread helps a bit further as it mentions the used GPIO's and such: https://ww...

Hello again, those Wiska boxes are quite fine for this, no metal blocking WiFi. you may check signal easily - can you connect to the ESP's webpage over that distance? Signal strength? If the signal is too low there might be a possibility: There is a new edition of the ESP-07, the ESP-07S http://www....

Hello there are two parameters which influence the reporting time inside ESPEasy. - open the ESPEasy website. - go to "Config" - locate "Sensor Delay" field. Sensor Delay says how often ESPEasy "talks" to domotics, openHAB, FEWHM, Thingspeak or whatever. - go to "D...

if i may suggest anyways.... Replace the LED with an optocoupler. It separates the ESP from your circuit reliably and can be read with a standard GPIO input.

Hello, A somewhat simple solution might be an opto coupler. The 817 (EL-817, KB 817, LTV 817 or similiar) is cheap, just some cents. opto.jpg It might be possible that the 680 Ohm resistor is a bit too much, depends on your cabling. The current through the opto coupler LED should be 5..6 mA, check w...

Hello. These boards are widely spread under the name "ESP-01 S". Please remember, that the RAM chip used (W25Q80) has 8 Mb (Mega bit ), not 8 Megabyte. Use the 1024 binary for flashing. Even some older ESP-01 were delivered with 1 MByte (8 Mbit) but that never worked out well for me, i all...

Hello, yes that is possible. You may use the "Global Sync" for this. The following works at least under the R148, should work on 2.0.0 too. For (very) short: - First check the "Config" page of your ESP's: There must be a unique unit number for both ESP's (1 ... 31) - Goto "D...

Hello Jufo, As promised I did a quick check with a nodeMCU (ESP-12E with Programming adapter) on a breadboard. Hardware is same as you did, just i hadn't placed the capacitor on the breadboard.

Although this is an old thread - i guess some people might still be interested how to definately solfe the RF-induced false triggering problem. You simple need to solder a 220nF ceramic capacitor across pin12 und pin13 of the chip (BISS0001) so that the high-frequency interference coming from the E...

Shardan

Ooooops?

hm... does the Ds still get power?

Maybe put a capacitor around 100µF near the sensor between 3,3V and ground.
The DS takes around 5 µW so it is not likely it overloads the power supply of the sonoff.
Maybe the 3,3V line isn't really "clean".

I'd second paxi. Is that a company computer in an active directory? Then there might be a policy denying access to .exe files.

maybe the DS-sensor is broken?
Try another one or connect it to another ESP for testing.

Hello, uhhhhm... GPIO 16 might be a bad choice as it has an additional function hardcoded inside the ESP chip. It is used to wake up the ESP from deep sleep mode. I use GPIO16 as output only. First check: Is the "Sleep Mode" box checked in the ESPEasy "config" tab? It should not ...

Hello, can't say what's going wwrong with your sonoff. I have DS18B20's working on different GPIO's without problem on my ESP's. Did you put a pull up resistor from the GPIO to 3,3V? (10 KOhm) If you use GPIO 4 or 5 there might be the I2C active on these pins. You may set the I2C pins in the "H...

The problems with fake FTDI chips are caused by an up to date driver. Older drivers may run - if they are availlable at all for W10. More problem is that the new FT232 driver is rolled out by win-update automatically. You may block Driver updates with Windows .- but that stops all drivers from upda...

Hello Frank, the 47µF or similar should be an additional capacitor at the end of the cable near at the DHT22 at 3,3 V and ground. It does not replace any of the other capacitor mentioned above.

First: Please use a separate power supply, not the one on the board. One wrong touch and it gets really dangerous. As paxi said, the USB adapters usually don't give enough power for that. Which memsize did you choose? If i remember right, the sonoff basic has 1 MB so you should use the 1024-binary. ...
