--[[ Quickapp P1 Monitor readme

This Quickapp retrieves energy consumption, energy production, gas and water usage from the (P1 Monitor) energy, gas and water meter. This Quickapp uses the software of ztatz.com to get the values from your smart energymeter. The ztatz plug-and-play software can run on a Raspberry Pi or in a Docker container.

The Energy consumption and energy production are added to the HC3 energy panel. Use the child devices Todays Consumption and Todays Production to store energy data (kWh) in the Energy Panel. And use the child devices Consumption and Production for instantaneous power (Watt) in the Energy Panel calculations.

Child Devices for:

• Consumption (Watt) (input for instantaneous power in Energy Panel calculations)
• Production (Watt) (input for instantaneous power in Energy Panel calculations)
• Todays Consumption (kWh) (input for energy panel)
• Todays Production (kWh) (input for energy panel)
• Waterflow (Liter)
• Consumption High (kWh)
• Consumption Low (kWh)
• Production High (kWh)
• Production Low (kWh)
• Consumption L1 (Watt)
• Consumption L2 (Watt)
• Consumption L3 (Watt)
• Production L1 (Watt)
• Production L2 (Watt)
• Production L3 (Watt)
• Ampere L1 (Amp)
• Ampere L2 (Amp)
• Ampere L3 (Amp)
• Voltage L1 (Volt)
• Voltage L2 (Volt)
• Voltage L3 (Volt)
• Total Gas (m³)
• Total Waterflow (m³)

Interval: It is possible to process messages from the smart meter every second. Of course, this is only possible if the smart meter actually sends a message every second. This can be turned on via the ztatz software P1 port configuration page via the "maximum processing speed" option. Note that this gives a higher load on the Rpi (or Docker). It has been tested on the Rpi3/Rpi4 and works well on it. Older or other RPIs have not been tested.

The P1 Monitor QuickApp uses 2 API calls each cycle, and if you also use Waterflow, 3 API calls each cycle. With an interval setting of 10 seconds there is an API call every 5 seconds (and with Waterflow enabled, every 3.33 seconds). So the fastest interval setting will probably be 3 seconds with Waterflow and 2 seconds without Waterflow.

Ztatz software: https://www.ztatz.nl Docker container based on the ztatz.nl software: The container version has the same functionality as the full version for the Raspberry Pi. Docker container: https://hub.docker.com/r/mclaassen/p1mon

  • Watt -> com.fibaro.powerMeter
  • gas -> com.fibaro.gasMeter
  • water -> com.fibaro.waterMeter
• Removed Power device calculation
• Removed child devices for gross consumption and device consumption
• Changed code to multi file
• Added for translations for English, French, Polish and Dutch

Version 1.6 (8th January 2022)

• Changed the waterflow algoritme to show more stable and more acurate measurements
• Small change in the code for checking existance of waterflow sensor
• Changed the Waterflow unit from Liter to L/min

• Added Lasthour gas to labels
• Changed the API request for status to json output

Version 1.5 (4th September 2021)

• Support of new Energy Panel:
  • Changed Child device Net Consumption to Main device with type com.fibaro.powerSensor (value can be positive or negative)
  • Added Child device Todays Consumption to show the daily energy consumption in kWh
  • Added Child device Todays Production to show the daily energy production in kWh
  • Changed Child device Consumption High and Low to com.fibaro.energyMeter (kWh in property "value"; "rateType" = consumption). These values will be shown in the new energy panel. 
  • Changed Child device Production High and Low to com.fibaro.energyMeter (kWh in property "value"; "rateType" = production). These values will be shown in the new energy panel. 
  • Added automaticaly change rateType interface of Child device Consumption High and Low to "consumption" and Production High and Low to "production"
  • Changed Child device Consumption and Production to type com.fibaro.powerSensor (Watt) to show power graphs
  • Changed Child device Consumption L1, L2 and L3 and Production L1, L2 and L3 to type com.fibaro.powerSensor (Watt) to show power graphs
• Additional changes:
  • Added todays Maximum consumption and todays Maximum production and timestamp to the label text and Child device log text
  • Added todays Maximum consumption and todays Maximum production automatic format measurement to W, Kw, MW or GW

  • Added todays Consumption of gas in the label text and Child device log text
  • Added Timestamp in format dd-mm-yyyy hh:mm:ss to log of Main device and labels
  • Placed production below consumption in the labels
  • Solved bug when Production is higher than Consumption with calculation of Gross Consumption (Gross Consumption = Net Consumption minus or plus Device Consumption)
