NOTICE PLEASE READ - ESPproMon Server


#1

It has now been more than 6 months since we released the ESPproMon firmware. Regrettably only a handful of users have bought the firmware during this time.

The cost of using the servers provided by Blynk and the time required to support ongoing firmware updates means the project is not financially viable in the current form.

Therefore, with regret, the current system will be disabled in the next few days.

As some of you know we also have our own cloud server, independent of Blynk, and it would technically be possible to migrate to this server. It would mean that users would run the Blynk app rather than the ESPproMon app and an ESPproMon project within the Blynk app.

There are some advantages to this as the Blynk app is being constantly improved with new features etc. We could re-code the firmware to use WiFi Manager in place of Blynk provisioning.

Using our own server would keep costs to an acceptable level but at this present time the user base is probably too low to warrant the migration. We will keep this under review and advise accordingly in due course.

Dear @Costas take your decisions and let us know. As you know I am one of your clients.

Best Regards,
Mike Kranidis

P.S. it is sad that your fine App did not attracted users. I think that it was deserved it …


#3

Dear @Costas,
a few days ago the application stopped to work as you told us. What is the next step?
Thanks and Best Regards,

Hi Mike,

At this time there are no plans to support the ESPproMon firmware.

Could you to provide source code on the arduino plataform for who bought the firmware?


#6

This is a very bad announcement for all of us that are your customers and we have paid your software. At least, as a good sign from you, release the Arduino sketch to us in order to make it in Blynk cloud.


#7

Anyone that is not happy can apply for a refund but the source code will not be made available.


#8

Ok how can I apply for refund? I am interested in as a fair solution.


#9

Hi Paul,
It’s a pity your APP is down right now… I wish you good luck for your future projects!!

Best regards

José.


#10

Refund processed.


#11

Thanks


#12

Hi, Sad to hear, but thanks for the support and help in the past days. I used app for reasonable time.


#13

Dear Sirs, now that the feature rich ESPproMON App permanently stopped working, I trying to reprogram my WeMos D1 mini that some days ago has @Costas firmware, to have a simplified cut down version running on the Blynk cloud. So far the early mockup is working. I have one question though: I know that the power factot is something that we can calculate, so what is the formula to do this calculation? I have the standard PZEM-004 and I use the most popular Arduino library:

Thanks in advance for your help.

Best Regards,
Mike Kranidis

To answer my question, for the help of anyone looking for this, see the below link that explain everything:

Power factor is included within the library provided by olehs, you don’t need to calculate it.


#16

Thanks @Costas.
I use this library but I found only Voltage, Current, Power and Energy. What function is for Power Factor?


#17

Take a look at pf in https://github.com/vortigont/PZEM004T/commit/c20dfab4efd2bdd7b35a89cc5cfb1d547b00d13e#commitcomment-22861581

Many thanks @Costas. I did already "outside"the library, as you can see, it is just a simple calculation.
Thanks anyway.
