Problem with Meteohub on Raspberry Pi Model 3

[MrPippoTN]

Hello everyone, I am writing to ask you for help. I have a Davis Vantage Pro2 connected to a meteohub installed on Raspberry Pi Model 3:

Linux Kernel: 4.4.27 2000 BogoMIPS, 947 MB RAM, Raspberry PI Model 3
MeteoHub: 5.1e (Build 276) ©2020 by smartbedded GmbH
System ID: xxxxxxxxxxx activated

A strange thing happens to me. After configuring the Meteohub, the data should update on this web page every 5 minutes:

http://www.meteotrentinoaltoadige.it/st ... ollaro.php

Unfortunately, after one or two updates, the page does not update anymore, the upload stops because there is a problem with the communication between Meteohub and Davis Datalogger. I copy the error logs:

Sometimes the upload restarts, but then it stops again.
I do not understand if this is a problem related to the datalogger, the raspberry pi, the sd card (new, 8 GB Kingston)... Help me please.

Is this a new Meteohub install? Or did it previously work?

If it is a new install, why not put that Pi 3 to better use? Instead run Meteobridge, as Meteohub is end of life (no more feature development).

EDIT: I should have looked at post history. I see now that you are a long time Meteohub user.

[MrPippoTN]

Yes, this is a new installation.

I'm a very old user of meteohub and meteobridge, as I'm part of an Italian weather network and so I manage a lot of different weather stations. This one is new!

I decided to use Meteohub because, before this Raspberry Pi, the real owner of this installation used to have a Iomega iConnect for a Davis Vantage Vue. Now he has a brand new Davis Vantage Pro 2 and so we decided to upgrade the hardware, keeping the old meteohub license.

In fact, the iConnect was very slow. If meteobridge will solve the problem, we will pass to meteobridge but we must be sure of it. He doesn't want to pay for a new license and have the same problem.

[galfert]

The Meteobridge would certainly work better. You can test the Meteobridge software for 14 days free trial. But be certain to use strictly enforced approved SD card fist.

You can order from Mouser or Arrow and they both do world wide delivery. I recommend the WD/SanDisk SDSDQED-016G-XI.

I've realized that the Raspberry's USB power charger I'm using is only 1 Ampere. Should it be the problem? Tonight I'll try a 2.5 A power charger.

I've realized that the Raspberry's USB power charger I'm using is only 1 Ampere. Should it be the problem? Tonight I'll try a 2.5 A power charger.

Is a 2.5 amp charger compatible with the battery? Will you harm the gadget? Still, it is better to use the adapters provided by the manufacturer.

As you can see from the recommended power supply for the 3B from raspberry pi.org, the recommended power supply ( not battery charger as the RPi isn’t powered by a battery ) is 2.5A. The minimum necessary current is 1.2A so a 1A power supply is too small.

“The power supply requirements differ by Raspberry Pi model. All models require a 5.1V supply, but the current supplied generally increases according to model. All models up to the Raspberry Pi 3 require a microUSB power connector, whilst the Raspberry Pi 4 uses a USB-C connector.

Exactly how much current (mA) the Raspberry Pi requires is dependent on what you connect to it. The following table gives various current requirements.

Product Recommended PSU current capacity Maximum total USB peripheral current draw Typical bare-board active current consumption
Raspberry Pi Model A 700mA 500mA 200mA
Raspberry Pi Model B 1.2A 500mA 500mA
Raspberry Pi Model A+ 700mA 500mA 180mA
Raspberry Pi Model B+ 1.8A 1.2A 330mA
Raspberry Pi 2 Model B 1.8A 1.2A 350mA
Raspberry Pi 3 Model B 2.5A 1.2A 400mA
Raspberry Pi 3 Model A+ 2.5A Limited by PSU, board, and connector ratings only. 350mA
Raspberry Pi 3 Model B+ 2.5A 1.2A 500mA
Raspberry Pi 4 Model B 3.0A 1.2A 600mA
Raspberry Pi Zero 1.2A Limited by PSU, board, and connector ratings only 100mA
Raspberry Pi Zero W/WH 1.2A Limited by PSU, board, and connector ratings only. 150mA
Raspberry Pi have developed their own power supplies for use with all models. These are reliable, use heavy gauge wires and are reasonably priced.

For Raspberry Pi 0-3, we recommend our 2.5A micro USB Supply. For Raspberry Pi 4, we recommend our 3A USB-C Supply”

Thank you but it was not the power charger. I've decided to go meteobridge. Solved.

[galfert]

Thank you but it was not the power charger. I've decided to go meteobridge. Solved.

There is no "power charger" when referring to Raspberry Pi. It is a "power adapter" or "power supply" or "power brick"...etc. This is because there is no "charging" occurring.

[MrPippoTN]

Sorry for my English. Power whatever, that wasn't the point.
I've tried with an original Raspberry 2.5 A power stuff, with no result. Same problem. I solved with Meteobridge.
