The "hidden" features in the firmware of the Wi-Fi energy meter
Because of the continued upgrading of the firmware, new features often appear in the latest firmware, this article is used to list all the features that have been supported by the firmware（will be updated continuously）.
How to get the latest firmware
We will release the latest firmware version here.
Select the run mode of the energy meter
There are three run mode selections.
- Cloud: use the energy meter together with IAMMETER-cloud, this is the default mode.
- TCP: upload data to third-party server by TCP,TLS or MQTT.
- HTTP: upload data to third-party server by HTTP or HTTPS.
T
Cloud
This is the default mode. It will upload data to IAMMETER-cloud. Then you can monitor the energy data by the IAMMETER cloud, the effect is like this: visit the IAMMETER-cloud by the demo account
Please note: there would be the different effects when you click the demo link in the browser of desktop mode(web system effect) or phone mode(app effect)
TCP,TLS and MQTT
TCP && TLS
Please refer to https://www.iammeter.com/docs/integrate-with-thirdparty-server
Video: Upload the energy monitor data to a third-party server
MQTT
Please refer to https://www.iammeter.com/docs/integrate-with-mqtt-server
HTTP or HTTPS
- The data format of the http/https post is the same as tcp/mqtt/tls mode.
- you can use different port to do the http post.
- if you use the port of 443, the energy meter would do the https post (only support https in port 443)
Local API
/api/moinitorjson: return the measurement result
Return all measurement results of the Wi-Fi energy meter in Datas field.
The Datas contains such parameters below (if it is 3 phase energy meter,it will return all three phase readings)
Voltage, current,active power,forward kWh ,reverse kWh,frequency,power factor.
Besides the measurement results, it also returns the SN, mac, and the firmware Version.

/api/monitor: Advanced version of "monitorjson"
Add two more JOSN fields. SSID: connected AP name. Sig: signal strength of the connected AP.
{"ssid":"CMCC-laohe","sig":100,"mac":"B0F8933C4F94","version":"i.75.97.9","server":"em","SN":"3E0BAF87","Datas":[[220.0,9.99,2198,11.337,11.201,49.99,1.00],[222.5,9.99,1100,11.039,10.908,49.99,0.50],[263.5,9.99,1213,10.975,10.846,49.99,0.55]]}
/api/wifidata: return the Wi-Fi network configuration
{"version":"i.75.97.9","SN":"3E0BAF87","mac":"B0F8933C4F94","type":"PM","ssid":"CMCC-laohe","ip":"192.168.11.62","netmask":"255.255.255.0","gw":"192.168.11.253","dns":"114.114.114.114","dhcp":1,"runMode":"cloud","netmeter":0,"uploadinterval":60}
/api/uploadinterval?x=value: set the upload interval value
http://ip/api/uploadinterval?x=value
Set the upload interval in seconds. Please notes ,the upload interval of the cloud mode is fixed in 1 min. This interval only work after you have set the the energy meter to upload the data to third-party server (by tcp, tls,http or mqtt).
/api/mqtt: Set the username and password of MQTT
please refer to https://www.iammeter.com/docs/integrate-with-mqtt-server#22--set-the-username-and-password-of-mqtt
/api/netmetring : the net metering mode of the energy meter
Please refer to How to use the net energy metering mode in the Wi-Fi Energy meter
Modbus/TCP
This is a big upgrade of the firmware ,so we list it independently here.
Support Modbus/TCP in the Wi-Fi energy meter of IAMMETER
request the energy data from the Modbus/TCP in the home assistant
