¶ ThingSpeak
Useful to easily enable remote viewing of the BMS data over the internet. Many of the selectable charting fields can be sent to the cloud data storage service, entirely based on your preferences.
Note: WatchMonToolkit software is required to be running to push updates to cloud.
The software automatically reduces the updates when the values are stable and sends more frequently when changes occur. With quick response down to 15 seconds and stretching to 5 mins to reduce bandwidth when the system has no changes.
There are up to 3 channels/agents that can sent up to 24 fields, below are the defaults:
-
¶ Agent 1 - CellMon related
- Field 1 - Cell Volt Min
- Field 2 - Cell Volt Max
- Field 3 - Cell Volt Average
- Field 4 - Cell Temperature Min (Celcius)
- Field 5 - Cell Temperature Max (Celcius)
- Field 6 - Bypass Current Max (Amperes)
- Field 7 - Bypass Temperature Max (Celcius)
- Field 8 - number in Bypass
-
¶ Agent 2 - Shunt Soc% related
- Field 1 - SoC%
- Field 2 - Shunt Voltage
- Field 3 - Shunt Current (Amperes)
- Field 4 - Capacity to Empty (Ah)
- Field 5 - Recent Consumption - Charging
- Field 6 - Recent Consumption - Discharging
- Field 7 - Daily session cumulative - Charging (Ah)
- Field 8 - Daily session cumulative - Discharging (Ah)
-
¶ Agent 3 - Remote Inverter/Charger related
- Field 1 - Charge Actual Voltage
- Field 2 - Charge Actual Current (Amperes)
- Field 3 - Charge Target Voltage
- Field 4 - Charge Target Current (Amperes)
- Field 5 - Discharge Actual Voltage
- Field 6 - Discharge Actual Current (Amperes)
- Field 7 - Discharge Target Voltage
- Field 8 - Discharge Target Current (Amperes)
¶ Guide
¶ 1. Go to ThingSpeak.com and click sign up.
¶ 2. Create account where you will push your data to.
¶ 3. Create a channel.
¶ 4. Configure the channel.
NB: Other field labels have be choosen, these are typical options we have defaulted.
¶ 5. Configure the visual charting options.
NB: This only highlights the basic options. For more information, read the documentation available from ThingSpeak.
¶ 6. Sample outline
Here is a outline of the example we have adopted as the demo for both the private and public view of the channel.
¶ 7. Copy the WriteKey to configure within the WatchMon Toolkit.
¶ 8. Within WatchMonToolkit navigate to Tools > ThingSpeak Client.
¶ 9. Configure the WriteKey with matching configuration.
Configure and enable up to 3 agents.
¶ 10. Select you preferred fields using the Wand selection.
NB: Align to settings within ThingSpeak, alternatively press the default button.
¶ 11. Press Start to store the configuration and run the processing agent.
