Let's Control It

dynamicdave

The command you posted doesn't look right.

Have you tried...

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.

I've tried with ESP_Easy_mega_20201130_normal_ESP8266_4M1M and can operate the GPIO pins by sending 0 or 1 to the topic.... homeDevice/command/gpio/12 In fact I can control the GPIO pins with... homeDevice/command/cmd/gpio/12 as well !!! Which is the correct format? It's the single string "Ok&q...

dynamicdave

I'm sending a value 0 or 1 from Node-RED to this topic... homeDevice/command/gpio/12 The subscribe setting in ESP Easy for Home Assistant (openHab) is.... homeDevice/command/# I can send an event command e.g. homeDevice/command/cmd to trigger one of rules - and that works fine. So what's the new for...

dynamicdave

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. My rule-set works fine with releases up to this date, but not after it. I'm using ESP_Easy_mega_20201022_normal_ESP8266_4M1M on...

Where would I locate the P087_SerialProxy plugin ?

dynamicdave

Has anyone any useful links on how to WiFi-enable an Arduino Nano with an ESP-01 running ESP Easy ?? I've looked around on the web and found most documents are either "old" or don't specifically mention using ESP Easy. My objective is to collect information from a remote weather station an...

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...

dynamicdave

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...

Hi, I'm using this command in a Rule-Set... Publish,weatherStation/reading,'{"node_number":"%sysname%"}' It works fine in... mega-20200410 But none of the later releases work. i.e. mega-20200426, mega-20200516 and mega-20200608 Please let me know if there is a more appropriate pl...

dynamicdave

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......

dynamicdave

I thought the json string needed single quotes around the curly brackets... (in the recent ESP Easy releases)

Code: Select all

Publish,<mqtt topic>,'{"latitude": [gps#latitude],"longitude": [gps#longitude], "Altitude": [gps#altitude], "Speed": [gps#speed]}'

dynamicdave

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. The other thing.. I think you should have single quotes around your json string in your publish command publish ...

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...

dynamicdave

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. I've found it very easy to set-up and get working especially as I teach a class of IoT students, where we have 12 Raspberry Pi(es) running Node-RED on a network with 1...

I've just lashed up a INA219 with a Wemos D1 Mini (FW=mega-20191003) and get correct readings I've got a 330 ohm resistor across the 3v3 rail (so the current should be 10mA). As you can see from the screen-shots the current is 10mA. The only differennce I can see is I'm using a "Measure range&q...

Here's a link to a write-up of a solar-powered weather station one of my IoT students tackled last year (2019). Didn't modify the (power routing on the) Wemos D1 Mini as didn't know about the CH340 issues and I doubt if our soldering skills would have been good enough. Ran the weather station with n...

dynamicdave

In full-screen mode it appears at the BOTTOM with a window showing the rules to the RIGHT.

If I reduce the width of the window, then it moves to the TOP of the screen.

I don't have an issue with that behaviour.

Hi,
I've tried the following FW on a WeMos D1 Mini and can confirm the Rule Set selection is WORKING again.

ESP_Easy_mega-20200328-15-PR_2972_normal_ESP8266_4M1M.bin

dynamicdave

I get exactly the same problem - can't change to another rule set.
I suspect the drop-down buttons aren't working.

dynamicdave

Here's a link to a Solar-Powered Weather Station project one of my IoT students tackled last year (July 2019).
It includes a write-up on using 'Deep Sleep' with a Wemos D1 Mini running ESP-Easy.

Hope you find it helpful/useful.

dynamicdave

What I do in Node-RED is to use a MQTT-Out node (running Mosquitto) which is set-up with the IP address of your server then set-up the topic in the MQTT-Out. Something like... nodeXX/gpio/14 Where nodeXX is the 'Unit Name' as used in the ESP-Easy Config tab. 14 relates to the GPIO pin, which in this...

dynamicdave

I think I read somewhere the nested level depth was three(3).
(Which by coincidence is what my code has.)

So are you saying that I should remove all the comments?

I only put them in the code to make it obvious as to what was happening.

Thanks for your valuable feedback

dynamicdave

Thanks.

Is there any speed/performance issues with the way I've implemented it?

Note:
I did code it your way at the start, then thought I could improve the layout/readability.

Thanks again for your swift response.

dynamicdave

This may seem a silly question. I've just got this rule-set working to turn an individual LED on depending on the numerical value in an 'event' sent via MQTT (from Node-RED to a Wemos D1 Mini). I'm surprised it works as I thought that ESP Easy didn't support nested IFs. I'm running mega-20200222 on ...

dynamicdave

Well I'm sort of hoping that now we have left the EU (I live in the UK) we'll be able to change the colour of our wires back to the scheme we had when I was a lad.

Red was Live
Black was Neutral
Green was Earth

Ha, ha, ha - wishful thinking.

dynamicdave

Wooo - that must be a world record.

dynamicdave

I'm using the ESP-Easy release 20200204 although this problem appears in previous releases. I'm sending a series of commands (like the following) from Node-RED to a Wemos D1 Mini using MQTT. msg.payload = "oledcmd,clear"; node.send(msg); msg.payload = "oled,1,1,Weather Report"; /...

dynamicdave

Hi @djelau Thanks for your response. The only thing I was concerned about was damaging (i.e. KILLING) the PZEM-004 by connecting the AC connections the wrong-way round. I can't wait for the energy sensor to arrive so I can get the system up and running - sounds like a lot of fun. PS: I've ordered th...

dynamicdave

Thanks for the feedback. Yes the current is measured using a coil clamped around one of the mains cables. My question was... does it matter which way round the L and N wires are connect in respect of destroying the PZEM-004 ? From your response I think it doesn't - just might affect the reading. Dav...

dynamicdave

I've just ordered a PZEM-004 v3 from China (with the external split CT sensor) - this particular version is housed in a plastic box for safety. I'm a bit confused as to the correct connection for AC mains as they seem to vary between photos. On the function diagram (screenshot-090) it shows 'Live' o...

dynamicdave

You can also take it a stage further and publish it as a json string. That means you could pack a number of data-items in the string. Here's an example from one of my rule-sets. Publish,node24/ir_detector,'{"ssid":"%ssid%","node_number":"node%unit%"}' Notice t...

Only just seen this thread. I spent a couple days (a month or so ago) trying to sort out why the ESP-01 didn't work after I used the programmer, shown above, to flash it. Discovered like a few people that a pull-up is missing on SOME of the ESP-01 boards. I had a mixture of boards, so some worked an...

This is what I use in my weather station, and it works fine.

I'm not familar with that particular servo, however I found I needed to power my miniature servos from a separte power supply otherwise the sudden current surge as the servo starts to move puts the ESP8266 (Wemos D1 Mini) into reboot. Just something worth checking, as my servos appeared 'dead' the f...

Hi, I'm trying to get an HC-SR05 ultrasonic distance sensor to work with a Wemos D1 Mini and wanted to know the best version of ESP Easy to use. Although the sensor report distances, the readings sort of jump from reasonable distances to a fixed value of 1038. I'm using a level shifting board, so th...

dynamicdave

What's wrong with sending the sensor data from the ESPs, via MQTT with a rule-set, to a Raspberry Pi running Node-RED ??
You can then do all sorts of things with the data... store it on the Pi's SD card (local file), write it to a database (local or remote) or send it to other places.

dynamicdave

When I first started using the ESP01s I bought a couple of these 'combo' boards. https://www.aliexpress.com/item/33019915868.html?spm=a2g0o.productlist.0.0.67df2ba3zsw2Od&algo_pvid=c32924df-5564-466b-ab3a-94687209cdfb&algo_expid=c32924df-5564-466b-ab3a-94687209cdfb-41&btsid=6636b3e5-cf69...

dynamicdave

I had exactly the same problem with two batches of ESP01s.
Drove me crazy for a couple of days!!!

Eventually found adding a 10K pull-up resistor from CH_PD to VCC sorted out the problem.

dynamicdave

Sounds like a nice job for a Virtual Private Network (VPN). Although there are some free offerings available, you could consider using a Raspberry Pi (even an inexpensive RPi-Zero-W would work) and installing PiVPN on it. It would also mean that your parents don't reveal their internal IP address to...

Just checked my notes about the Wemos D1 Mini (a ESP8266-based microcontroller). The (new versions of the) Wemos D1 Mini have a couple of resistors (on-board the PCB board or maybe inside the chip) that act as a voltage divider. There's a 220K resistor in series with a 100K that connects to ground. ...

Well what a coincidence... I've just been writing a tutorial for my IoT students on the Witty module. Yes it does have an on-board LDR connected to A0 (analog input) as per the schematic linked to above. The integer readings I'm getting range from 17 (total blackness) to 1024 (full light from the fl...

With some help from a friend I've got it working.

The MQTT topic should be... node68/cmd

And the payload should be... servo,1,14,120 (to move to 120 degrees)
