Missing battery_blocks data on PW3 with Multiple Powerwalls in Local Mode

[JohnJ9ml]

Version 0.12.1:

My local API calls for system_status and anything else that should show battery_blocks returns a count of zero and an empty array.

My installation has three PW3 units.

The information was missing previously when I was running in cloud mode as well.

"rawData" : { "all_enable_lines_high" : true, "auxiliary_load" : 0, "available_blocks" : 0, "available_charger_blocks" : 0, "battery_blocks" : [ ], "battery_target_power" : 0, "battery_target_reactive_power" : 0, "blocks_controlled" : 0, "can_reboot" : "Yes", "command_source" : "Configuration", "expected_energy_remaining" : 0, "ffr_power_availability_high" : 0, "ffr_power_availability_low" : 0, "grid_faults" : [ ], "grid_services_power" : null, "hardware_capability_charge_power" : 0, "hardware_capability_discharge_power" : 0, "instantaneous_max_apparent_power" : 0, "instantaneous_max_charge_power" : 0, "instantaneous_max_discharge_power" : 0, "inverter_nominal_usable_power" : 0, "last_toggle_timestamp" : "2023-10-13T04:08:05.957195-07:00", "load_charge_constraint" : 0, "max_apparent_power" : null, "max_charge_power" : null, "max_discharge_power" : null, "max_power_energy_remaining" : 0, "max_power_energy_to_be_charged" : 0, "max_sustained_ramp_rate" : 0, "nominal_energy_remaining" : 13150, "nominal_full_pack_energy" : 42450, "primary" : true, "score" : 10000, "smart_inv_delta_p" : 0, "smart_inv_delta_q" : 0, "solar_real_power_limit" : null, "system_island_state" : "SystemGridConnected" }

The raw output to the pw.tedapi.get_battery_blocks() call actually returns the battery block data.

converted to an object:
"battery_blocks": [ { "battery_power_status": "on", "can_connection": "can1", "enable_inverter_battery_meter": true, "enable_inverter_solar_meter": true, "max_soe": 100, "min_soe": 0, "pvi_power_status": "on", "type": "Powerwall3", "vin": "1707000-21-K--TGXXXXXXXX3JZH" }, { "battery_power_status": "on", "enable_inverter_battery_meter": true, "enable_inverter_solar_meter": true, "max_soe": 100, "min_soe": 0, "pvi_power_status": "on", "type": "Powerwall3Follower", "vin": "1707000-21-K--TGXXXXXXXX3DZE" }, { "battery_power_status": "on", "enable_inverter_battery_meter": true, "enable_inverter_solar_meter": true, "max_soe": 100, "min_soe": 0, "pvi_power_status": "on", "type": "Powerwall3Follower", "vin": "1707000-21-K--TGXXXXXXXX309Y" } ] }

Hi @JohnJ9ml - I suspect we need to add some logic to detect PW3 installs and pull the relevant data from tedapi. Can you help by running a few things for me? I don't have a PW3 to test.

# TEDAPI (full)
#
import pypowerwall
PW_GW_PWD="XXXXXXXXX"
PW_HOST="192.168.91.1"
pw = pypowerwall.Powerwall(PW_HOST, gw_pwd=PW_GW_PWD)

# Flags
print(f"mode: {pw.mode} - tedapi: {pw.tedapi_mode} - pw3: {pw.tedapi.pw3} - vitals: {pw.vitals_api}")

# Battery Blocks
print("pw.battery_blocks():")
print(pw.battery_blocks())
print()

# I believe this is what you posted above - please confirm

# System Status
print("system_status():")
print(pw.system_status()) # Is this the one missing?
print()

# TEDAPI Reported Battery blocks
print("pw.tedapi.get_battery_blocks():")
print(pw.tedapi.get_battery_blocks())

I'll confirm all of your items above:

Yes, pw.battery_blocks() is empty.

Yes, pw.system_status() says I have zero battery blocks.

Yes, pw.tedapi.get_battery_blocks() sees them:

`python batteryBlockDebug.py
