An acquaintance tempted me to try AI. I did. I asked the following
question very simply, in my own language:
----------------------------------------------------------
I'm looking for an Arduino program for the D1 Mini ESP8266 that, using
the Wi-Fi data from the Pi dongle from HomeWizard
(http://192.168.1.206/api/v1/data), outputs the value from
"active_power_w":721 serially at a baud rate of 9600, preceded by a -"*".
----------------------------------------------------------
I promptly received this response in Dutch:
--------------------------------------------------------------------------
I'm creating an Arduino program for your D1 Mini ESP8266 that reads
the active_power_w value from your HomeWizard P1 dongle and outputs it
via serial communication.
-----------------------------------------------------------------------------
And in less than a minute, I had a program which I loaded into the
module, and it promptly delivered what I wanted on its serial output!!!
And all I know is how to load it with Arduino.
On the one hand, it's incomprehensible and amazing, but on the other,
I get a shivering feeling.
Is this our future???
regards Hans

Hi Rob,
I find it very complicated. Simply reading the meter's serial
output and then extracting the value you need is much simpler, I
think. That's how I've done it in the JAL so far.

Hi Hans,
It does not look exactly like JSON but I do not know if there
are variants. This is one line of more than 1000 characters.
You can parse that realtime and if that is not possible you
have to store it in data memory first.
Kind regards,

Hi Rob,
No problem. I have my well-functioning PIC project with a
wired connection to the battery charger, and I can then
use that to apply the partial charge.
Connecting it to the D1 was a laborious (but instructive)
adventure of patching and trial and error.
So, for me, the only profit would be replacing the wires
with Wi-Fi.
As my wife keeps saying, "You're still having fun with
it," so, well, give me the JAL anyway.
Best,
Hans

Hi Hans,
I cannot follow the program completely but that may be
because I do not know what Homewizard needs and returns.
Note that the Arduino program is using a JSON library.
There is no JSON library for JAL (yet). Not sure how
often such a library would be used.
Kind regards,
Rob

Hans van Veldhuizen:
Hi Rob,
Correct, I'll see what I can do with your
instructions.
I'll try to explain it.
I currently have a PIC package that reads the
smart meter and records how much is input (IN) or
output (OUT).
I use two potentiometers to set an ON and OFF
value. It then switches a relay on via a wire when
the OUT value is greater than the ON value and
stays that way until the IN value is greater than
the OFF value.20250325_122333[1].jpg
I can now replace the wire with the Arduino D1
mini and a Homewizard socket because I also have a
Homewizard dongle in my smart meter. Besides
reading and forwarding the on/off commands from
the PIC, the D1 mini also sends back the socket
status.
Why I'm being so difficult (besides the fact that
it's an incurable deviation of mine) is because
the Homewizard system turns the socket ON when
there is a minimum feed-in value, but always turns
the socket OFF when there is no more feed-in. I've
asked them many times to adjust that, but they refuse.
With my approach, I accept a partial load.
For example, the panels have a surplus of 1 kW and
the charger has a capacity of 2 kW. Therefore, the
HW will constantly switch on and off. Now, mine
will accept a 1 kW supply from the grid before
switching off. So, winter situation.

Hi Hans,
If I am correct you want to control a
Homewizard device for which you need a Wifi
connection using an ESP8266, right?
in 2019 I made a library for the ESP8266. What
needs to be done is that you - after the
module is connected to the Wifi - send data
via the serial interface tot the ESP8266 which
then sends it to your HomeWizard device via Wifi.
Without looking at this in detail I think it
should be possible using this JAL library.
Kind regards,
Rob

Hello everyone,
I've deleted my previous message because I've
found the creator of this program willing to
help me. It's working properly now.
With the PIC, I can now send ON/OFF commands,
and if the sockets respond correctly, I get
the message back that I can read with the PIC.
A truly perfectly working package!!!!!
The world of Arduino remains a stumbling block
for me, no matter how simple it should be
according to the experts. I'm therefore
surprised this thing cannot be implemented in
the PIC/JAL world. If anyone is interested in
delving into this, I have a PCB lying around
that I'd be happy to send to you.

Hi Vasi,
Wow, what a fantastic package! Very
clever, and it's just missing the little
bit I need! Too bad, but maybe someone
else knows.
By the way, I have a few UNOs here that I
occasionally use to try out a program from
the internet.
But often, it doesn't work.
On Wednesday, I linked a program for the
D1 mini V3 I ordered; let's hope it works.
Then I can use a PIC instead of the
pushbuttons and continue.

Hi Hans,
Unfortunately, my knowledge does not
contain the required information. Many
times ago I developed my own CMS
(content manager system or blog)
written in PHP language and using a
MySQL database, then later developed
some plug-ins for the sNewsCMS
(porting also some Wordpress plugins
for the same system) but after a
couple of years I got bored and
decided that further web programming
is not something satisfying enough -
that time, my access to Internet was
limited and expensive. I went back to
PC programming in other languages and
then entered in the embedded world.
Now I gather/realize projects with
ATmega micros in C, Wiring, LunaAVR
and GCBasic (maybe even FreePascal,
not decided yet) languages for a book.
Probably, next is PICO, exactly what I
recommended to you... Circuit Python
and Micro Python are unknown to me for
now. I could go with C or FreePascal
but a future book is the main target.

HELLO Vasil,
If I were 30 years younger, I
would definitely embrace your
proposal. Unfortunately, there are
limits.
Another question that you, with
all your knowledge, can surely answer.
When I open this on my PC, I get
the correct data response from the
Homewizard socket.
http://<IP ADDRESS>/api/v1/data
also http://<IP
ADDRESS>/api/v1/state gives
the correct answer
The instruction I used also tells
me how to get it to "ÖN", but I
can't get it to work in a single
line on my PC.
http://<IP ADDRESS>/api/v1/state\
-X PUT\
-H "Content-Type: application/json"\
-d '{"power_on": true}'
Perhaps you can do that and would
like to tell me.
Thanks in advance.

Hans,
It will be much easier for you
to learn CircuitPython and use
a Raspberry Pi Pico board with
WiFi support than torture
yourself with Jal and PIC...
Then, along the way, you can
migrate to MicroPython for
complete freedom and a plus of
performance.
I think this is the best long
term solution for Jal users
that cannot learn
C/C++/Wiring. I thought and
searched for solutions and
there is no other solution
better than this. There is
FreePascal for Pico boards but
it has so limited support that
you cannot call that a solution.
If you cannot enter in the
wonderful world of craftsmen
using Arduino, then skip it
altogether for the next world
that uses PICO boards with
CircuitPython. That is the
future you are about to miss
if chose not to act.

Ask ChatGPT to translate that

CircuitPython source. See if
it is easier for you to
understand and use. Act
accordingly.
