Let's Control It

I totally agree with TD-er, using EasyEDA and JLCpcb to design and then manufacture your PCB is very easy and inexpensive. I have created 12 or more board-designs over the last 3-years and have been really pleased with the results. I live in the UK and JLCpcb charged me £3.71 (including postage and ...

I've just downloaded release ESP_Easy_mega_20230409_normal_ESP8266_4M1M.bin and flashed it on a Wemos D1 Mini. It seems a lot faster at booting-up and/or reconnecting the WiFi in about 5 to 6 secs. Previous releases, for me on the Wemos, were very slow. Thanks guys for another great release. PS: Hap...

dynamicdave

Just tried that option - no difference in boot time.
It will be interesting to see if my friend in Boston, USA (who also uses Wemos D1 devices) encounters the same boot-up time.

If I revert to Mega_20220809_normal_ESP8266_4M1M.bin, the boot time is 5secs

dynamicdave

Just tried... normal_beta_ESP8266_4M1M
It takes the same length of time (approx 15s) to boot-up/connect.

dynamicdave

I mainly tested stability on the latest ESP8266 SDK3.x ("beta" builds) and not the older SDK. Where do I find that version? The sequence I performed was... I downloaded ESPEasy_mega_20230306_ESP82xx_binaries.zip from the website, then unzipped it and used ESP_Easy_mega_20230306_normal_ESP...

dynamicdave

Just flashed ESP_Easy_mega_20230306_normal_ESP8266_4M1M onto a Wemos D1 Mini (that I've been using for a year or two with various releases of ESPeasy). It takes nearly 15-seconds from pressing the Tools > Reboot option to when the blue LED comes on. Are there any specific options I should be using w...

dynamicdave

I've encountered the same problem (long time to connect to WiFi) on the last two releases on a Wemos D1 Mini.

The last release that gave an acceptable connect time for me was... Mega_20220809_normal_ESP8266_4M1M.bin

dynamicdave

I've deleted my circuit in case it caused confusion.

dynamicdave

Deleted

dynamicdave

That's a wide-open question with loads of potential answers. What hardware, software and sensors have you access to? I assume you are running ESPeasy on some sort of platform (which one)? Can you give us some idea of what projects previous students at your university have tackled? Also is this a fir...

dynamicdave

Thanks for your swift response.
It's not an issue as I can handle it the way I'm doing it now.
Much better for the 'Team' to concentrate on higher priority features/issues.

dynamicdave

Thus, if it were possible to set the user prefix globally, it would be cool! A theoretical solution would be to add string type vars to ESPEasy. Besides general purpose use, they could be used as string substitutes in the application you mentioned. For example, initialize the string var at boot in ...

dynamicdave

No idea what you are using the other pins for - but if you have I2C running on them you could consider the PCF8574A I2C Port Expander.
Probaly not a lot of difference in cost between this chip and a Wemos D1 Mini.

dynamicdave

Have a look at this excellent document. https://randomnerdtutorials.com/esp8266-pinout-reference-gpios/ It also depends how you are driving the relay. I suspect you are using a transistor driven from a D-pin. You have to be mindful of what happens to certain pins during boot-up. This is because you ...

dynamicdave

Thanks I did wonder about events stacking up.

Just tried using... AsyncEvent,rules#timer=1
Works really well.

Thank you.

dynamicdave

Thanks for the suggestion to use... event,rules#timer=1 That works really well for my current project. Basically what I have is a 300-second timer. Every time it expires (every 5-mins) it will collect a temperature reading and sends it, via MQTT, to Node-RED where it is stored in a MySQL db and show...

dynamicdave

In the documentation it says it 'disables' the timer (which is what seems to happen in my rule-set).

TimerSet,<timernr>,0 (disables the timer)

I just wanted to clear or reset the timer.
I'll try the TimerSet_ms,<timernr>,<time in msec> command as I didn't know that existed.

dynamicdave

Is there a way to clear a timer that is running? Say, for example I have a timer that runs for 30-secs and I want to clear it so... On Rules#Timer=1 Do fires What I'm doing at the moment (which works fine) is setting the timer to 1-second ( timerSet,1,1) so one second later the rule fires. Just wond...

dynamicdave

Thanks for the heads-up on that - I will certainly give that a 'try' today.

dynamicdave

I have an old ESP01-S running ESP_Easy_mega_20200703_normal_ESP8266_1M that picks up 17 APs when I do a Scan for WiFi networks. I also have a Wemos D1 Mini (also an ESP8266) running ESP_Easy_mega_20211005_normal_ESP8266_4M1M that only picks up 3 APs. These two devices are sitting right next to each ...

dynamicdave

Thanks for all your help. I have no idea what has changed from this morning. I swear it wasn't working and none of the other versions would work until I got back to 2020127. Now after reflashing (again) with 20211105 it has decided to behave itself!!! Makes me out to be a fraud !! Totally confused o...

dynamicdave

I don't believe this - I couldn't wait until tomorrow, so I went and got all the kit and reflashed it with... ESP_Easy_mega_20211005_normal_ESP8266_4M1M
It appears to be publishing the switch states now via MQTT.

dynamicdave

Well it is developing into a fun project. I'm using Alexa with some nodes in Node-RED, so I can say things like... "Alexa, open garage door" or "Alexa, close garage door" I dropped one of the remote control key fobs the other day - broke the plastic case - BUT the electronics sti...

dynamicdave

It's really strange - it works fine in mega-version ESP8266 20201227, but in later versions it doesn't. I've spent too much time on it today, but will insert some debugs, as suggested, and see if it is entering... on top#level do I'm actually using a Wemos D1 Mini fitted with a 4Mb chip and an ESP01...

dynamicdave

I'm probably doing something incorrectly, but I can't make a rule for a normal switch to work after release esp8266-normal-2020-1227 I have two switches named top and bottom. I can see the values changing if I look on the devices tab. But the rule dosen't want to publish the value. If I send an even...

dynamicdave

The main problem with using a board with an on-board regulator like the NodeMCU 12E or the Wemos D1 Mini is... The INA219 needs to be placed in the supply rail/pin in order to measure voltage and current. This is tricky as it means cutting and re-soldering tracks - something I would AVOID at all cos...

dynamicdave

I think (from my faded memory) the IN219A measures 'things' in the high-end.
So far, I've not encountered any problems using these devices.

dynamicdave

I use a Wemos D1 Mini (ESP8266-based) and a IN219 in my weather station to report the voltage/current/wattage of the solar panel that is connected to the Wemos. The IN219 has an I2C interface so it is very easy to connect it to the Wemos. Also the series resistor in the IN219 (which is used to measu...

dynamicdave

The command you posted doesn't look right.

Have you tried...

Code: Select all

http://192.168.86.43/control?cmd=GPIO,15,1

dynamicdave

I would have thought the publish command should be...

Publish,%sysname%/BOFF/status,1

Publish,%sysname%/BOFF/status,0

dynamicdave

This is the version I think is the latest in the link you sent me.
It doesn't work - it still sends a log.

Just noticed that from ESP Easy release 221016 onwards MQTT (OpenHAB) seems to be publishing what looks like a log and the topic-name has not resolved the system variables.

dynamicdave

I've not used the S26, but I have many of the S20 version in use around my house here in the UK. I operate them from Node-RED via MQTT protocol. The S20 is very easy to flash with ESP Easy or Tasmota as it has four pads on the PCB that bring out the connections you need. All you need to do is solder...

dynamicdave

Thanks - that works a treat.

dynamicdave

Just checking if there is a 'ping' option in any of the recent ESP-Easy releases.

The last one I found that had it was 20190311 2.5 and 2.6

Regards, David

dynamicdave

What a great use for a INA219 - I might try that out with a spare Wemos D1 Mini as the current scope.

dynamicdave

It will be interesting to hear if anyone else who uses BeeBotte as their remote MQTT broker has had any problems recently. Note: When I use the 'extended' credentials tick-option it seems to corrupt the token in the Controller User box after I do a re-boot. I'm sure my friend in Boston (who uses Wem...

22 characters

e.g. token_MpvmXXXXXXXXXXeX

It includes the word... token_

dynamicdave

I think I've managed to sort out the issue. I'm using BeeBotte as my remote MQTT broker. I've found you have to insert the BeeBotte API Token in BOTH the Controller User and Controller Password boxes. The ESP Easy release dated 20200410 - you only had to enter the token in Controller User box. Not v...

Just a quick observation... in the original circuit there was a diode between RST and D0.
This has disappeared in the recent schematics - is it important?
No too sure as to the function of the diode, perhaps someone could explain.

dynamicdave

As your turn-off times are the same in both cases, you could use just one timer. on System#Boot do GPIO 0,1 endon on Clock#Time=%sunrise+1h% do // 1 hour after sunrise... GPIO 0,0 // turn on relay TimerSet,1,600 // wait for 10 minutes endon on Clock#Time=ALL,13:30 do // Give the plants some lunch......

Hi, I found an old post about the problem in using VAR as the name for a variable. Although I've been using VARS since that time, I didn't have time to update the example/tutorial, sorry.

dynamicdave

Sorry I'm a bit late to the party... I'm paranoid about connecting a voltage directly to an input pin (just in case it was mis-configured as an output). I just use an extra resistor to limit the current and protect the input pin. I usually use two resistors connected as per the attachments. Fig-A is...

I use the Home Assitant (OpenHab) MQTT feature on ESP Easy, purely to send/receive information to/from Node-RED running on a RPi-4B.
