![]() ‘aa’ changes up/down a bit, but it is also not clear what it means.The 3 bytes have this format: 0xaa 0xbc 0xcc To go into the past increment the index and wrap around at 365 till you hit today again. It is a cyclic buffer with an index pointer in the header pointing at todays position. The outletHeight is an offset that is added to the level to return the volume of the tank. It is used to convert the level in cm into liter. This table is calculated by the tank type A-C automatically, but can be customized to match any shape (tank type D). If the distance between the top and the transmitter is 0, the capacity is the maximum value. The table has one value per cm tankHeight – up to 300cm is supported. The distance from the bottom of the transmitter to the top of the fluid. 0x28: 0x08 Outlet Height outletHeight in cm (0.70cm).0x27: 0x00 Sensor Offset sensorOffset in cm (0.70cm).Because the history starts yesterday, you need to start with the next index for yesterday. 0x13: 0x002d 45 Index to todays entry in the history historyIndex.0x0a: 0x0064 Height of the tank without the rounding? (Probably entered during configuration).0x08: 0x0048 Width of the tank? (Probably entered during configuration).0x06: 0x0096 Height of the tank in cm (here: 150) tankHeight.If the table is modified via a computer, the type is set to D (3). 0x05: 0x03 Type of the tank A.D (0.3) The tank offset table is calculated by the device based on the setting (A-C).0x00: 0xcc (204) Magic byte, always checked to test the communication with the device.If there is no description, the value is unknown. 365 days of average usage – a round-robin buffer.tank air space table (liters of tank volume based on the level above the fluid (0.300cm)).2 byte full capacity of the tank in l (16-bit, big-endian).2 byte usable capacity in l (16-bit, big-endian).2 byte sensor level in cm (16-bit, big-endian). ![]() The get the temperature in Celcius you need to calculate it like this => temperatureC = ((temperatureF - 40 - 32) / 1.8)
