Version history
v0.1 2020-11-30 Initial commit, save history of selected packets, settings
v0.2 2020-12-05 Hysteresis, vertify commands sent to P1P2
v0.3 2020-12-09 More effective and reliable writing to P1P2 bus
v0.4 2020-12-10 Minor tweaks
v1.0 2023-XX-XX Major upgrade: web interface, store settings in EEPROM, P1P2 error counters
changes:
- only Daikin E* heat pumps (Altherma)
- no SW_SCOPE
- no error budget
- no write budget (Write Cycles can are displayed via web UI)
- use single queue for all write packets (0x3X, counter requests, daikin restart, etc.)
- write all packets after 0x30 (disable #define KLICDA writing after 0x12 packet)
- write any packets (incl. counter requests, restarts, etc.) only if connected as controller
- if the main controller sends request to our auxiliary controller, always respond
v1.0 2023-04-18 Major upgrade: web interface, store settings in EEPROM, P1P2 error counters
