Bugfix the 2.75.92
1 exists abnormal kilowatt-hours (kWh) data when an old energy meter (with an old version metering module firmware) upgrades the WiFi firmware to the latest version

This is the bugfix version of 2.75.92.
If you use an energy meter that runs an old metering firmware(not the Wi-Fi firmware) and upgrades the Wi-Fi firmware to 2.75.92, you may meet abnormal kWh data occasionally.
This version (i.75.96) is the bugfix version for 2.75.92.

More feature:

1 Stable version that supports Modbus/TCP.   How to use the modbus tcp function in Wi-Fi energy meter of IAMMETER

You can refresh the data from Modbus/TCP each second.

2 Add a run mode of  "stand-alone" 

select the run mode as "HTTP" and keep the "HTTP Address" as empty , then the energy meter will enter stand-alone mode, it will never send any data out, only respond to the local API and modbus tcp/rtu requst.

3 change the function of the API that changes the upload interval

HTTP://ip/api/uploadinterval?x=12

Now, the unit of "x" is second, you do not need to calculate the upload interval by any formula anymore.
the range of x is 12(seconds)-1200(seconds)

4 Bugfix of the previous version.

SHA256:5E551579F7B68CF40363596A82D6376BC3A5275978DC12761A9432FD6C52F831

Upgrading list

2.75.76@ 20220225 

1 resolve the problem of memory leak caused by MQTT disconnection
2 resolve the possible "brick" problem in the upgrading process.


2.75.69@20211110

IAMMETER has been upgraded recently, including

  1. Support uploading meter's data to IAMMETER-cloud and third party MQTT server using MOTT
  2. Support setting meter's data upload interval by users
  3. Support setting WEM3080T (3-phase WiFi energy meter) to net metering mode

 

 

 

1. MQTT

1.1 Upload data to IAMMETER-cloud using MQTT

1.1.1 Configuration

Currently, you can set MQTT server configuration on configuration web page.

image-20210722155047592

Run Mode: TCP

TCP Address: mqtt://mqtt.iammeter.com:1883

1.1.2 The benefit of uploading data to IAMMETER-cloud using MQTT

In this case, the data upload interval can be set by users. The minimum data upload interval can be set as 6 seconds.

Please note that the minimum data storage interval on IAMMETER-cloud is 1 minute, which means that even the data upload interval is set less than 1 minute (6 seconds for example), IAMMETER-cloud also stores the data in every 1 minute. However, you can subscribe the related MQTT topic, and then the subscribing result refreshes in according with the data upload interval (6 seconds) preset by you.

For how to subscribe the topic from IAMMETER-cloud, please refer to https://imeter.club/topic/20

1.2 Upload data to third-party MQTT server

Authentication mode: ClientID without password or Anonymous

Topic :device/sn/realtime

2 Change the data upload interval

To understand how the data upload interval setting works,please click here

 

2.1 Set the data upload interval

You can change the data upload interval by local API as below:

http://ip/api/uploadinterval=N

Method: HTTP get

N: The parameter to calculate the data upload interval, which can only be natural numbers. The formula to calculate the data upload interval (T) is,

T = (N+1) * 6

The unit of T is seconds.

For example, as shown in below picture, if we set the N as 1, then the uploading data interval is

T=(1+1) * 6 = 12

So the data uploading interval is set as 12 seconds.

 

image-20210723132147707

2.2 Get the data upload interval

 

After setting the data upload interval ,you can test it using below API.

http://ip/api/wifidata

Method: HTTP get

Hello,
Where can I see what kind of model I have?

I bought a 3 phase from Aliexpress which currently has the firmware ATV1.75.32@MX1290 on it!

Hi Michael :

The 3 phase energy meter is WEM3080T. You can upgrade your firmware to the latest firmware that posted here.


Best Regards

Hello,

Thank you for the update, seems to work fine. Would it be possible to increase the update interval to 1 per second?

I'm not interested in the energy values, but mainly the power values to regulate other stuff.


Thank you!


Hi:

Make the upload interval less than 6 seconds will bring some problems in our current logic, when we find a better method to solve these problems we will consider shorter this 6seconds interval.

Strange... doesn't work here...

I've done all exactly as stated: 

- updated  FW to latest (ATV2.75.66@MX1290)
- entered mqtt address  (mqtt://mqtt.iammeter.com:1883)
-entered zero for 6 seconds (http://192.168.x.x/api/uploadinterval=0)
- set to net metering mode in my iammeter webpage

but on my "overview" page data still updates only once per minute, and even this updates only if i click on "overview" each time. On your youtube video data is automatically refresed... So, what did i miss?

My meter is 3-phase model.

Hi:

Please try to read the upload interval and check whether it had been set to zero as you wanted.

refer to this:

   2.2 Get the data upload interval


If it had been proved set to zero, you can subscribe this mqtt data of this SN and check whether the data refresh every 6 seconds.

Hello!

I'm very sorry for my silence, but right after my post i've been sick for a while, and after that i kinda forgot this problem. I remembered today when i received my monthly consumprion report... with all ZEROES? I have zero kWh consumption for each day for whole september. Even my current consumption graph on overview page (power, grid consumption) show nothing - empty graph, just current power. Going back from net metering to normal and current consumption show graph is populated with data again, but it seems that september history is gone. 

So, for now i'm gonna stay at "normal metering". History is more important for me than current data send every 6 seconds. And,BTW... i double-checked: i have data upload interval correctly set to zero (which means 6 seconds). I didn't check MQTT though, because of the problem, mentioned above.

Hi:

This post is mainly for the introduction of the latest firmware.
Please post your question in a new thread. It will be more clear and easy to discuss.

Hi iAmmeter people.  

In regards to the MQTT configuration . . . Are you planning on implementing authentication at some point, this is virtually useless to a large majority of people that actually care about the security of their systems.

I understand your concern.
But now, the MQTT is just an option for some amateur that can be integrated into their own service easily.
We have not considered clearly whether it will affect our current service if we introduced extra authentication in mqtt.
If you are worried about the data security in MQTT publishing, you can consider the TLS method,

This is a video tutorial about how to upload the energy data of the energy meter to a third-party TLS server.

Hi There,

I just tried upgrading the latest firmware. And it looks like it died. I can ping it and and my router detects the mac address. But I can't get to the web page. Have you got any ideas or is it destined for the bin?

Hi, the firmware before 2.75.70 has the risk of bricking the energy meter in upgrading.
It is a very low possibility, but the risk indeed exists.
It occurs in such abnormal situations.
when the upgrading is not complete you initial an upgrading again(use another browser to upgrade the firmware).

So we inform the risk at the top of this post.


The firmware after 2.75.70 has already been without this possible risk.


If you confirm your energy meter is bricked after upgrading(please power down it and wait more than 10 seconds to restart it )
The only method is to send it back to us, we will help you to recover it.




 tried resetting the unit while in the switch board and it appeared not to have booted up after software upgrade.

Removed it and tested one more time on my test bench. And it worked as did the upgrade.

Maybe I wasn't patient enough..

So far all good.

Yes I am interested in when Iammeter will be implementing an authentication with MQTT, hopefully soon as that is one of my mine complaints about it.

Hi lmaso90 and pspeirs:

Please advise more details about the authentication you mentioned.

In fact, we found a lot of authentication methods in MQTT are provided by the specific MQTT broker software, not a universal way. 


The current mechanisms are as below.

USE IAMMETER-cloud
When you publish energy data to IAMMETER, it uses the serial number of the energy meter as the authentication key.
When you subscribe to the energy data from IAMMETER, there are more authentication factors. username, password (from the MQTT setting in the IAMMETER system), and serial number are all required.

Please refer to 

https://www.iammeter.com/docs/integrate-with-mqtt-server

https://imeter.club/topic/20#subscribe-real-time-data


USE third-party MQTT broker.

Only the serial number of the energy meter can be used in the authentication.


Thanks.

Hi, 

I have WEM3080T can i upgrade the newest FW? (2.75.92) 
Thank you for your reply. :)

Hi laoliu,

Thank you for your fast reply, The question is, can i upgrade the newest FW? YES or NO :)

Hi:If you have never upgraded the firmware before(the 2.75.66 is the original version of your product) ,it is ok.

Hi zsgodor

If you have never upgraded before and the firmware is  2.75.66 now,  you can upgrade the latest firmware.


If you have upgraded the firmware from an old version to the 2.75.66,  because I do not know the first version, so I am not sure whether it can upgrade or not in this case.

Hi laoliu,Thank you for your fast reply, The question is, can i upgrade the newest FW? YES or NO :)

Dear Laoliu,

I previously upgraded to 2.75.66 from the original.
Before that, the factory FW was on the device.
Intermediate firmware of 2.75.76 has not been updated.
So I can't even upgrade to 2.75.92 now?
The device works properly as long as it doesn't matter I don't need to update.

Thank You for your support.

Hi:
In theroy, you need to confirm the factory FW version before you do the upgrading.
But if you do not remember the factory FW verson, this is my suggestion.
1 if you are really want to use the new feature of the latest FW version. you can do the upgrading.
2 if the current FW already meet your requriement, just keep it .

Have a good day. :)
