Allow SetupEnergyStats for non BL / Tuya power meters

[analystcmyk]

The power statistics command (SetupEnergyStats) is a great tool, but unfortunately hardcoded to be used only for power measured using the BL driver.

definition

Suggestion : allow statistics to be collected for other type of meters, eg Tuya powermeters.

My autoexec.bat ( using EARU EAMPDW-TY-63 ) :

startdriver SSDP
startDriver TuyaMCU
startDriver NTP
tuyaMcu_defWiFiState 4
setChannelType 1 toggle
linkTuyaMCUOutputToChannel 16 1 1
setChannelType 2 Voltage_div10
setChannelType 3 Power
setChannelType 4 Current_div1000
setChannelType 5 EnergyTotal_kWh_div100
linkTuyaMCUOutputToChannel 1 0 5
linkTuyaMCUOutputToChannel 6 RAW_TAC2121C_VCP
linkTuyaMCUOutputToChannel 15 1 7
ntp_timeZoneOfs 2:00

Thank you for considering.

Maybe overstretching and out of scope here, but possibly this would not be strictly to be limited to power.

Any value could be "statted" using the sample period , but it would mean having to calculate and store min/max/avg per sample period, while currently we only hold the total per sample period.

Example : Value = Temperature , Sample time = 5 seconds, Sample count = 2

Any plans for moving the stats out of the BLE code? Even just a daily diff like https://github.com/openshwprojects/OpenBK7231T_App/blob/c07f66f3818c7067e60acbf27cb1a5d86f77e692/src/driver/drv_bl_shared.c#L187 would be nice (instead of the full fledged configurable powermeter)

Maybe a script can do the same thing, ill try that as well.

Show energy usage of last hour:

• global total is CH5
• create intermediate counter CH10
• create intermediate counter to store usage of last hour CH11
• every 3600 seconds, store global total (CH5) in CH10
• if CH5 changes, calculate the difference between CH5 and CH10, and store in CH11

Of course this is not a real running hourly total, as it will reset to zero every hour. A moving window would be better, sharing here anyway.

// measure 1 hr usage, $CH5 holds total kWh

// store the last measured value
setChannelType 10 EnergyTotal_kWh_div100
setChannelLabel 10 EnergyTotal_1hr

// set to total when booting 
// check if you need a wait time, some tuya's do not have this value yet when booting
setChannel 10 $CH5;

// channel to hold the usage of last hour
setChannelType 11 EnergyTotal_kWh_div100
setChannelLabel 11 EnergyUse_1hr

// every hour, reset the counter
addRepeatingEventID 3600 -1 111 measure1hr

// and keep updating the hour totals when the energytotal changes 
addEventHandler OnChannelChange 5 measure1hr_update

alias measure1hr backlog setChannel 11 $CH5-$CH10; publishChannel 10; setChannel 10 $CH5;
alias measure1h_rupdate backlog setChannel 11 $CH5-$CH10; publishChannel  11;
