The versioning received an update because the logic in it was nowhere to be found. It is now based on:
- [YY].[M].[#] [Release type]
- Example: 26.2.1 stable
Releasse date: 2026-05-14
Changes:
- Added 1 new models to be recognized
- Removed old reference to deprecated WAR variables
- Fixed incorrectly aligned [remove] button in sensor line 3
- Fixed bug #218; No HEAT setpoint for zone 2 being sent at all.
- Fixed a small bug where the scheduler could throw an error in case a day/hour/minute has not been entered yet.
Release date: 2026-04-11
Changes:
- Modified behaviour for RTC automation. It is more robust now. Always triggers, even after restarts
- Heat setpoint on Dashboard - Home is now always up-to-date
- Added 3 new models to be recognized
Release date: 2026-03-05
Changes:
- New heishamon firmware 4.0 released. Confirmed working perfectly
- Added 5 new models to be recognized
- Modified the behaviour of Force_DHW logic. Should be more robust now
Version 26.2.1 Stable
HUGE changes:
- Gave the project a name. Meet "HeishaMoNR"
- Added support for zone 2 (rewrite)
- Added support for buffer tank (rewrite)
- Added generic MQTT-command manager functionality. It checks if commands are picked up by the Panasonic. If not it retries 3x
Big changes:
- WAR renamed to CCC. (from Dutch WeersAfhankelijkeRegeling to CustomCompensationCurve, which makes more sense)
- Added a MQTT-command rate limiter to prevent/reduce panasonic dropping commands
- Added zone 2 support to CCC function
- Added zone 2 support to RTC function
- RTC Automations require a single target zone
- Added support for P1 meters which reports different data types. (type 1 / 2)
- Added extra external Link-In options. See right side of [WP Input]-tab.
Other noteworthy changes:
- SoftStart function rewrite to accommodate for buffertank and multizone setups
- Improved charts. Now surviving reboots
- Allow sending HEAT setpoints in all operating modes
- Removed all QoS 1 and 2 on mqtt nodes. It is not supported
- Added more Panasonic pump versions to detect
- Fan 2 auto-show/hide when it is detected
Existing limitations:
- Cool function only works in DIRECT mode. (still on the list to fix, but is on low priority)
Major changes:
- Firmware Support: Added compatibility with Heishamon Firmware 3.9
- SoftStart function rewrite: now with improved relax frequency and TCAP recognition
- Scheduler Enhancements: Added more actions
- Scheduler Enhancements: Added more advanced conditions (room/outside temperature thresholds)
- Sensors: Added extra 1-wire sensor support to show in graphs of DHW, HEAT, and ROOM temps
SoftStart function:
- SoftStart Fixes: Resolved bugs related to defrost phase and startup loops
RTC function:
- Multiple improvements to prevent premature triggering
- Multiple improvements for the reverting actions
- MQTT Fixes: Eliminated repeating commands like SetZ1CoolRequestTemperature
Charts & UI Improvements:
- Home screen: If Fan2 is present, it will show up (and stay) after first value enters.
- Home screen: Added Heater, it will show up (and stay) after first value enters. And when active, it will light up.
- Translated some chart labels from Dutch to English
Solar²DHW:
- Forced DHW-only mode during a run for better compatibility with HEAT+DHW
- Improved kWh calculations and graph visuals
- More robust energy tracking in Solar²DHW (fixed NaNs, graph is now more robust, but could increase loading a bit)
- Moved P1 setup to [SYSTEM] > [SENSORS] tab. Much better.
Miscellaneous Fixes:
- Reading Panasonic details logic rewritten for fw3.9
- Powerful mode toggle fix
- Added TOP115 pressure readout
