pytigo 0.4.1

Python client for the documented Tigo REST API v3

pytigo

pytigo is a Python client for Tigo solar monitoring systems, focused on near-real-time monitoring for time-series systems like Prometheus.

Two backends are provided, both satisfying TigoClientProtocol:

	TigoClient (cloud)	TigoCCAClient (local)
Transport	HTTPS to api2.tigoenergy.com	HTTP to CCA device on LAN
Auth	Bearer token (username + password login)	HTTP Basic Auth
System ID	From cloud account	Read from device summary_config
Telemetry params	Pin, Vin, Iin, RSSI, Temp, Tmod, Tcell, Tamb	Pin, Vin, RSSI, derived Iin
Lifetime energy	Yes	Not available (returns None)
YTD energy	Yes	Not available (returns None)
Daily energy	Yes	Yes (~12-day rolling window)
MPPT layer	Yes (from cloud layout)	Synthesized — one per string
Alerts	Yes	Not available (empty page)
Serial / panel type	Yes	Not available
Timestamps	UTC-aware from cloud	Local device time; adjust with tz_offset_seconds

Install

pip install pytigo

Quick start — cloud

from pytigo import TigoClient

client = TigoClient(username="[e-mail]", password="super-secret")
auth = client.login()

systems = client.list_systems()
system = systems.items[0]

layout = client.get_layout(system.system_id)
objects = client.get_objects(system.system_id)
sources = client.get_sources(system.system_id)
summary = client.get_summary(system.system_id)
aggregate = client.get_aggregate(
    system.system_id,
    start="2026-03-31T00:00:00",
    end="2026-03-31T23:59:59",
    level="day",
    param="Pin",
)
combined = client.get_combined(
    system.system_id,
    start="2026-03-31T00:00:00",
    end="2026-03-31T23:59:59",
    agg="day",
)
alerts = client.get_alerts(system.system_id, limit=10)
alert_types = client.get_alert_types()

Quick start — local CCA

from pytigo import TigoCCAClient

# tz_offset_seconds = local clock offset from UTC
# e.g. UTC-5 (EST) = -18000, UTC+1 = 3600, UTC = 0
client = TigoCCAClient(
    host="192.168.1.100",
    username="Tigo",
    password="$olar",
    tz_offset_seconds=-18000,
    # opt-in exploratory mode for raw temp variants like Iin/Tmod/Tcell/Tamb/Power
    enable_raw_temp_variants=False,
)
client.login()  # probes the device and builds topology cache

systems = client.list_systems()
system = systems.items[0]  # always one entry for the local device

layout = client.get_layout(system.system_id)
summary = client.get_summary(system.system_id)

# Pin (power), Vin (voltage), RSSI, and derived Iin are available locally
aggregate = client.get_aggregate(
    system.system_id,
    start="2026-04-06T12:00:00",
    end="2026-04-06T12:15:00",
    param="Pin",
)
rssi = client.get_aggregate(
    system.system_id,
    start="2026-04-06T12:00:00",
    end="2026-04-06T12:15:00",
    param="RSSI",
)
iin = client.get_aggregate(
    system.system_id,
    start="2026-04-06T12:00:00",
    end="2026-04-06T12:15:00",
    param="Iin",
)

Writing code against both backends

Use TigoClientProtocol as the type hint so your code works with either client:

from pytigo import TigoClient, TigoCCAClient, TigoClientProtocol

def build_client(mode: str, **kwargs) -> TigoClientProtocol:
    if mode == "local":
        return TigoCCAClient(**kwargs)
    return TigoClient(**kwargs)

def fetch_summary(client: TigoClientProtocol, system_id: int):
    client.login()
    return client.get_summary(system_id)

Cloud API areas supported (TigoClient)

• users/login, users/logout, users/get
• systems/list, systems/view, systems/layout
• objects/system, objects/types
• sources/system
• data/summary, data/aggregate, data/combined
• alerts/system, alerts/types

Local CCA status (verified against a live device)

Verified with local credentials Tigo / $olar on a CCA at 192.168.192.114:

Available local data endpoints:

• /cgi-bin/summary_jsconfig
• /cgi-bin/summary_config
• /cgi-bin/summary_energy
• /cgi-bin/summary_data?date=YYYY-MM-DD
• /cgi-bin/summary -> redirects to /summary/
• /summary/ -> authenticated UI page that uses the endpoints above

Known endpoints currently blocked by available credentials:

• /cgi-bin/info -> returns Access Denied.
• /cgi-bin/network -> returns Access Denied.

These should be re-checked in the future if higher-privilege credentials become available.

Local summary_data temp variants

The local CCA accepts temp= variants on /cgi-bin/summary_data.

Verified distinct variants:

• pin -> power-like panel telemetry used by local power example/client
• vin -> panel voltage telemetry
• rssi -> panel wireless signal telemetry

Derived variant exposed by the library:

• Iin -> panel current derived from Pin / Vin because the tested device's raw temp=iin payload matched temp=pin

For local Vin, the library auto-detects whether the CCA payload is already in volts (e.g. 30-31) or in tenths of a volt (e.g. 300-310) and scales accordingly.

Accepted but not distinct on the tested device:

• tmod
• tcell
• tamb
• power

On the tested CCA, those variants returned the same payload as pin. They are available only in opt-in exploratory mode by constructing TigoCCAClient(..., enable_raw_temp_variants=True) and calling:

• param="Tmod"
• param="Tcell"
• param="Tamb"
• param="Power"

Because these were not distinct on the verified device, they should be treated as raw/debug data rather than stable semantic metrics.

Observed but empty on the tested device:

• temp -> HTTP 200 with empty body

Local examples

• examples/local_cca_power.py -> auto-finds the latest populated Pin window and prints per-panel power
• examples/local_cca_endpoints.py -> probes local summary/info/network endpoints and enumerates temp= variants

Cloud live validation example

• examples/cloud_live_validation.py -> validates the official API v3 end-to-end against a real account and explicitly reports the known aggregate / combined limitation when those endpoints return only Datetime

Notes

The library returns typed Python dataclasses for JSON endpoints and a parsed TigoCSVTable for timestamped telemetry (data/aggregate, data/combined). The table format is designed for easy flattening into Prometheus, Grafana, or ETL pipelines.

For local CCA use, lifetime_energy_dc and ytd_energy_dc on TigoSummary will always be None — this data is not exposed by the device. Consumers should handle None gracefully for these fields when operating in local mode.
