evcc adapter for ioBroker

Controll evcc over rest api

Forum: https://forum.iobroker.net/topic/49165/neuer-adapter-iobroker-evcc

Charge mode (evcc >= 0.316.0)

evcc 0.316.0 renamed the mode pv to smart and replaced minpv with the separate setting alwaysCharge (evcc PR #32490). The adapter detects the evcc version automatically and keeps working with older versions.

State	Values	Note
`loadpoint.X.control.off` / `.now` / `.smart`	button	set mode
`loadpoint.X.control.alwaysCharge`	`off`, `on`, `once`	evcc >= 0.316.0 only, `once` resets when the vehicle is disconnected
`loadpoint.X.control.pvControl`	`0` off, `1` smart, `2` smart + always charge, `3` now	now also reflects the current evcc mode
`loadpoint.X.control.pv` / `.min`	button	deprecated, mapped to smart + alwaysCharge off / on

Breaking for scripts/visualizations: with evcc >= 0.316.0, loadpoint.X.status.mode reports smart instead of pv/minpv. Use loadpoint.X.status.alwaysCharge or loadpoint.X.control.pvControl to distinguish the former min+pv mode.

Charging plan

A static charging plan can be set per loadpoint under loadpoint.X.control.plan:

State	Meaning
`plan.active`	`true` creates/updates the plan, `false` deletes it. Reads back whether a plan is set in evcc.
`plan.time`	target time (timestamp in ms). Past or empty: now + 24 h
`plan.soc`	target SoC in % – used when a vehicle is assigned to the loadpoint (soc plan of that vehicle, same as `vehicle.<name>.plan.*`)
`plan.energy`	target energy in kWh – used when no vehicle is assigned (energy plan, e.g. vehicle without SoC / guest vehicle)

Values written while plan.active is false are only stored and used when the plan is activated, so set time and soc/energy first, then active = true. Note: evcc's own status.planActive means "currently charging according to plan", not "a plan is set".

Changelog

WORK IN PROGRESS

(Schimi1983) fix: polls took longer than the interval with many states (e.g. weather forecast) – values are now written in batches
(Schimi1983) fix: no errors in the log when the adapter is stopped during a poll
(Schimi1983) fix unit tests: chai-as-promised is no longer loaded in test setup (not a direct dependency anymore)
(Schimi1983) charging plan per loadpoint: control.plan.active/time/soc/energy (soc plan of the assigned vehicle or energy plan of the loadpoint), closes #73 and #18
(Schimi1983) repository checker (#135): remove test dependencies already provided by @iobroker/testing, CHANGELOG_OLD.md in .npmignore, consistent formatting of admin/jsonConfig.json

0.3.1 (2026-10-10)

(arteck) Dependencies have been updated
(Schimi1983) fix: enableThreshold / disableThreshold could not be set
(Schimi1983) fix: global control.smartCostLimit was sent to loadpoint undefined
(Schimi1983) fix: smartCostLimit / batteryGridChargeLimit = 0 now removes the limit (DELETE), negative limits are allowed
(Schimi1983) fix: chargeDuration / connectedDuration are reported by evcc in seconds (were treated as nanoseconds)
(Schimi1983) fix: vehicle plan (plan.active, plan.planSoc, plan.time) is read from and written to evcc again
(Schimi1983) remove unused calls to removed evcc endpoints
(Schimi1983) fix: control actions were called with the adapter as this instead of the evcc client
(Schimi1983) performance: objects are created once per runtime instead of being rewritten on every poll, polls no longer overlap
(Schimi1983) add units and roles (W, Wh, kWh, A, %, km, s, €/kWh, g/kWh, °C) for known evcc status values, indicator role for booleans

0.3.0 (2026-10-02)

(Schimi1983) support evcc 0.316 mode redesign: new control.smart and control.alwaysCharge, pvControl reflects the evcc mode
