Calypso connecté (modelId 1658) missing from model.py — falls back to "Unknown product (1658)"

[picosam]

Summary

get_model_infos() in model.py has no branch for modelId 1658, so an Atlantic Calypso connecté water heater falls through to the else at model.py:424 and is reported as Unknown product (1658) with type = CozytouchDeviceType.UNKNOWN. 1657 is already mapped as Calypso 200L with exactly the shape this device seems to need, so it looks like a natural template.

Thanks for the integration — it is the only thing that reaches this appliance at all, since the first-party Overkiz integration only sees the bridge Pod.

Environment

• Integration version: 1.4.0
• Home Assistant: 2026.7
• Protocol: Magellan (apis.groupe-atlantic.com/magellan). This appliance joins the house Wi-Fi directly and acts as its own gateway (gateway type: 1000), so it is invisible on the Overkiz surface — that account's enduserAPI/setup/devices returns only the CozyTouch bridge Pod.
• Device: reported name Calypso connecté, modelId 1658, firmware 2.7.3 (capability 121), 84 capabilities.

What happens today

Falling into the fallback sets only name, type = UNKNOWN, and HVACModes = {0: OFF, 4: HEAT}. Beyond the display name, two concrete effects traceable in the code:

1. HeatingModes is never set. Capability 87 is declared as a select bound to modelList = "HeatingModes" (capability.py:183-188), but select.py:77-81 falls back to self._list = {-1: "Undefined"} when that key is absent from modelInfos. The heating-mode select therefore offers a single Undefined option, so MANUEL / ECO+ / PROG cannot be chosen from HA even though the device reports and accepts the mode.
   Confirmed live (2026-07-24) after installing v1.4 against this device: the resulting
   heating-mode select entity reads exactly Undefined, while capability 87 simultaneously
   reports 3 (ECO+). So the device's mode is known but unselectable from HA — this is
   observed behaviour, not just inferred from the code.

2. Capability 99 is mislabelled. capability.py:202-208 branches on type == WATER_HEATER; with UNKNOWN this device exposes it as dhw_pump (mdi:faucet) rather than resistance (mdi:radiator).

Evidence from this unit

All read-only cloud reads; no writes exercised.

ID	Upstream name	Observed	Corroboration
87	heating_mode	3	The CozyTouch app showed ECO+ selected at the same moment, and the app's mode tabs match the {0: MANUEL, 3: ECO+, 4: PROG} enum. Only 3 = ECO+ is independently confirmed; 0 and 4 are taken from your mapping, not verified here.
121	firmware_version	2.7.3	Well-formed, matches the app.
179	wifi_rssi	-46	Matches -47 dBm measured independently by the Wi-Fi controller the device is associated with.
219	wifi_ssid	(redacted)	Matches the SSID the device actually joined.
22	target_temperature_dhw	54.5	Matches the setpoint shown in the app. Note this model exposes neither 160 nor 161, which capability.py uses for the bounds of the temperature_adjustment_number.
265 / 267	tank middle / bottom temperature	54.83 / 57.75	Plausible and consistent with the setpoint.

Two smaller observations that may be useful:

• Capability 312 (the # For test entry, Temp_312) reads 54.5 on this unit — identical to capability 22's setpoint.
• Capabilities 88 and 98 carry product/serial-style identifiers. Values omitted here; happy to share privately if they help identify the exact commercial variant.

Of the 84 capability IDs this device reports, 36 are mapped by v1.4's capability.py and 48 are not:

15, 23, 58, 150, 164, 168, 182, 188, 218, 223, 224, 228, 230, 234, 244, 252,
253, 278, 280, 281, 284, 285, 286, 288, 290, 304, 307, 308, 309, 310, 311,
329, 330, 331, 332, 333, 336, 337, 338, 339, 340, 351, 381,
105011, 105012, 105122, 105300, 105301

That list is orthogonal to the model mapping (those are covered by the "create entities for unknown capabilities" option) — included only in case an unmapped-ID inventory for a Calypso variant is of any use.

Suggested change

If 1658 is simply an adjacent Calypso variant, extending the existing branch would cover it:

elif modelId in (1657, 1658):
    modelInfos["name"] = "Calypso 200L"
    modelInfos["type"] = CozytouchDeviceType.WATER_HEATER
    modelInfos["HVACModes"] = {
        0: HVACMode.OFF,
        4: HVACMode.HEAT,
    }

    modelInfos["HeatingModes"] = {
        0: HEATING_MODE_MANUAL,
        3: HEATING_MODE_ECO_PLUS,
        4: HEATING_MODE_PROG,
    }

A separate branch may be preferable if 1658 deserves its own display name — I cannot determine the exact commercial designation or tank capacity from the API; the device reports its own name as Calypso connecté. I'd defer to you on naming.

Caveat stated plainly: since I have only read this device, I can confirm the fallback behaviour and the reported values, but not that mode-setting works once HeatingModes is populated.

Offer

A full 84-capability dump for this device is attached (dump_json output, scrubbed of
address/household/serial/account identifiers; capabilities 88, 98 and 219 redacted), and I'm happy to test a patch against the live unit and report back.

Account/address/household identifiers removed; capabilities 88, 98 and 219 redacted.

PR #152 opened.

One correction to this issue while I'm here: I reported the capability-99 mislabel as a second, separate bug. It isn't — it's a symptom of the same root cause.

capability.py already resolves 99 conditionally on modelInfos["type"], and the unmapped-model fallback sets type = CozytouchDeviceType.UNKNOWN. So 99 fell to dhw_pump purely because 1658 was unmapped. Adding the model branch with type = WATER_HEATER fixes both, and no change to capability.py is needed.

So the fix is one branch in one file, rather than the two-part change I originally proposed. Apologies for the noise.

HI, many thanks for this integration!
Having the same issue, so happy to provide any needed information, and eager to this model 1658 recognized.
FI 1658 is a 240l Calypso Connecté tank (as it seems. 1657 is a 200l tank)
