Version 2.8.4

13. May 2026

Added

• App/UI: New device category "Energy" with types Inverter, Smart Meter, EV Charger and Heat Pump
• App/UI: Energy device cards show key metrics (PV production, grid power, consumption); statistics icons for all energy mappings; feature buttons with separate PV, grid and consumption aggregation
• App/UI: Separate outdoor temperature feature button for weather stations and devices with outside_temperature — no longer mixed into indoor temperature average
• App/UI: Support for new display settings for devices (sorting, status display, value lists)
• Backend: free@home EV Charger (Wallbox) support — charging status, power, energy, boost mode and additional wallbox data points
• Config/UI: Numerous new Modbus-based device profile addons for heat pumps, wallboxes, inverters and smart meters
• Config/UI: New "Display" tab on device page with visibility, naming, sorting, status display and screensaver configuration
• Config/UI: Performance improvement for KNX address lists — automation builder and component assignment are significantly faster for large KNX projects with thousands of group addresses
• Daemon: Calculated Mappings for commandserver — cross-register arithmetic via {$REF$} syntax in mapping conditions
• Daemon: New MODBUS server type with dynamic CRC16 calculation (XXXX placeholder)
• Daemon: UDP response validation for MODBUS commandserver — automatically filters stray datagrams based on expected response size
• Daemon: New mapping filters %int16 and %int32 for signed integer interpretation of hex values (e.g. Modbus registers with negative values like power or current)
• Daemon: New parameter filter %hex8 — converts float values to IEEE-754 Big-Endian hex (8 chars) for Modbus write commands (FC 0x06/0x10)
• Daemon: New mapping filter %bitcode{N} — encodes a 16-bit register packed with alarm bits into a single integer (0 if no bit set, otherwise highest_set_bit + N), to aggregate multiple alarm registers into one mapping with valueList
• Daemon: New mapping filter %bitcode32{N} — 32-bit variant of %bitcode for wider bitfield registers
• Daemon: New mapping filters %shr{N} and %shl{N} — right and left shift with unsigned arithmetic
• Daemon: New SHUTDOWNCMD option for commandserver — sends device commands before disconnect and daemon shutdown
• Daemon: New sysvars [HOUR_HEX], [MIN_HEX], [SEC_HEX], [DAY_HEX], [WDAY_HEX], [MONTH_HEX], [YEAR2K_HEX] — return the respective time/date component as a 2-digit hex byte for direct embedding into binary protocol sequences (e.g. time/date sync on serial heating controllers)
• Daemon: [SYSVAR] tokens now usable inside CommandServer command sequences — re-resolved on every send so current values (time, date, system IP, etc.) can be embedded dynamically into device payloads. Opt-in via new CONFIG option RESOLVE_SYSVARS=YES so profiles with a literal '[' in sequences (e.g. JSON/REST) are unaffected

Changes

• Backend: Improved stability and performance of the Matter integration
• Backend: RTSP camera streams now use TCP+UDP instead of UDP only — improves compatibility with cameras behind NAT or on unreliable networks
• Backend: Improved Miele integration — more reliable cloud connection, fewer unnecessary API requests
• Backend: Improved Home Connect integration — more reliable cloud connection, new appliances are detected automatically
• Backend: Improved MQTT configuration — local broker is automatically secured when credentials are set, security check warns about missing password protection
• Daemon: mRemote GUI port (5500) has been closed and is no longer reachable
• Daemon: xPL network listeners (ports 49152+) are now only started when xPL definitions exist — reduces unnecessary open ports on systems without xPL configuration
• System: Security optimizations

Fixed

• Backend: KNX devices were occasionally shown as unreachable even though they were working
• Daemon: %swap32/%swap16/%float filters in commandserver and event mappings did not work correctly in HEX mode (hex-to-decimal conversion before filter chain prevented correct byte processing)
• Daemon: KNX connection status is now sent periodically so the backend can recover from lost status events
• Daemon: Hue Bridge was only detected as reachable again 11-14 minutes after a connection issue
• Backend: Home Connect skill logged itself out during temporary cloud outages
• Backend: Miele devices were incorrectly shown as unreachable during high cloud load
