Basic system overview.

1. Grid
From grid Tariff (LO, HI, D-LO, D-HI) and power from grid in W
Imported energy by tariff in Wh
To grid Power exported to grid in W
Exported energy in Wh
2. Plants
Produced Produced power in W and energy in Wh
Consumed Consumed power in W and energy in Wh
3. Storage systems
Sourced Power in W and energy in Wh sourced from storage (battery)
Stored Power in W and energy in Wh stored (to battery)
bargraph and %¹ SOC Battery State Of Charge
4. Consumers
Consumed Consumed power in W and energy in Wh
[] Status Output status for managed consumers
bargraph² Analog out Analog output value
click Toggle Click in frame toggles managed consumers output
long-press² Set analog Long press on first consumer pops-up dialog for analog value set
5. Unknown source
Sourced Power in W and energy in Wh from unknown source
:!: Accumulate also all differences caused by power-sensor inaccuracy
6. Other consumers
Consumed Consumed power in W and energy in Wh by other (not measured) consumers
7. Temperature and humidity
Temperature Temperature in ºC
Humidity Humidity in % RH

¹ only for eStore

² only for first managed consumer


Overview of current power distribution by source / consumer.

1. Sourced power
Sourced power for each source
Sums per source type
Total of all sourced power
2. Consumed power
Power for each consumer
3. Power distribution
Partial distributed power

1. Sourced power distribution
How sourced power is consumed by each consumer
2. Consumed power distribution
Who sources consumed power


Energy overview of a given time distributed by sources / consumers.

1. Sourced energy
Sourced energy for each source
Sums per source type
Total of all sourced energy
2. Consumed energy
Energy for each consumer
3. Energy distribution
Partial distributed energy
4. Energy since
Date and time since energy is recorded
5. Reset all
Long-press to reset all energy counters


Weekly timetable for managed consumers.

1. Managed load menu
Switch between managed loads
2. Enable checkbox
When un-checked timetable is not executed
3. Events grid
Events displayed in weekly grid (15 min resolution)
Click to select time and set event by clicking buttons below
4. Once actions (top priority timetable actions)
Actions are executed and then automatically cleared.
“Disable” action will just disable recurring action.
5. Recurring actions (low priority actions)
Actions are executed each week.
6. Analog out
Action to set analog output. Analog actions are recurring.
7. Cloud optimization
When enabled (checked) cloud optimization is enabled.


Weekly tariff timetable for grid energy per tariff distribution.

1. Tariff grid
Graphical weekly timetable with tariffs.
Click to select term, click-and-drag to select multiple terms.
2. Low tariff
Set low tariff for selected terms.
3. High tariff
Set high tariff for selected terms.


Easy and intuitive system setup.

1. System settings
[ autodetect ] Click to find HEMS G2 in local network
eStore c….. eStore serial number (automatically detected or can be entered manually).
[] enable When checked HEMS will read Grid, first plant and first Storage directly from eStore (so there is no need to duplicate power-sensor).
[detect] eStore address is cleared and new eStore can be detected.
HIQ Home c….. HIQ Home serial number (automatically detected or can be entered manually).
[] enable When checked HEMS will read Grid power and energy from HIQ Home (so there is no need to duplicate power-sensor).
[detect] HIQ Home address is cleared so new can be detected.
2. Internet access
[] enable When checked HEMS is automatically connected to HIQ Universe cloud service. The connection is initialized by the HEMS system and uses UDP packets on port 8442.
[test] New “push” message is sent to server and roundtrip time is rechecked.
[reset] Clear messages counts and roundtrip time
push timer Timer in s for send “push” message to server
messages Sent “push” messages / responses counters
roundtrip Time in ms between sent push message and response.
3. Sources and Consumers settings table
SOURCES Source name
icon Source icon
source management Source power-sensor management

timetable Manged consumer timetable execution enabled
4. Permanent memory parameters
[init parameters] Init all parameters to default value
[save parameters] Save all parameters to permanent memory
[read parameters] Read all parameters from permanent memory
[] autosave parameters Parameters will be automatically saved to permanent memory in 15 minutes after last parameter change
5. Backup / Restore to PC
[backup] Backup all parameters to PC
[restore] Restore all parameters from PC backup

¹ only for the first power plant

² wireless setting must be enabled

³ only for wireless modules and wireless setting must be enabled
