Does anyone know if GivTCP Xxxxxxx KWh is the actual value or a derivative from SOC?
The reason - The AC charge amount for overnight was 11.8KWh but the SOC KWh changed by 9.5KWh which is broadly where it be, if this was a derivative.
ispookie666 Don't know the answer, but don't fully understand the question either. Which Givtcp key:value pair do you mean? Also, it feasible that 11.8kWh went into the battery, some 2.3kWh came out and that left you with an overall increase of 9.5kWh?
One of the entities on GivTCP is SOC KWh, I initially presumed this was the actual measured value. Unfortunately it looks like it is derived from the SOC % .
I'm sorry, I framed the information open to interpretation. The actual charge overnight was 11.8KWh but the SOC KWh increase was only 9.5KWh, this does not include any discharge/was before any discharge started.
ispookie666 Can of worms ...?
The object returned by Givtcp to the /runall REST request brings back one set of data eg;
"Battery_Capacity":189.65,
“Battery_Cell_10_Voltage":3.287,
...
“Battery_Cell_9_Voltage":3.288,
“Battery_Cells":16,
“Battery_Cycles":154,
“Battery_Design_Capacity":160,
“Battery_Firmware_Version":3007,
“Battery_Remaining_Capacity":112.68,
“Battery_SOC":59,
...
“Battery_Temperature":23.4,
“Battery_USB_present":true,
“Battery_Voltage":52.618The MQTT package sent to the broker by includes
Battery_SOC = 59
Battery_Capacity = 189.65
Battery_Design_Capacity = 160.0
Battery_Remaining_Capacity = 112.18
Battery_Firmware_Version = 3007
Battery_Cells = 16
Battery_Cycles = 154
Battery_USB_present = True
Battery_Temperature = 23.6
Battery_Voltage = 52.289
Battery_Cell_1_Voltage = 3.266
Battery_Cell_2_Voltage = 3.264and the Home Assistant data, I just can't see any numbers in MQTT Explorer.
The above data was for the same battery but a few minutes apart. Nevertheless, the Battery capacity is the same at 189.65 (was 200Ah when new) compared to a "user available" Battery_Design_Capacity of 160Ah (8.2kWh). The SoC reported in both objects is the same at 59, which is Battery_Remaining_Capacity/Battery_Capacity, so 59% of the actual capacity rather than the "user available" capacity. 59% is also the value reported on the portal for this inverter's battery SoC.
This doesn't answer your question but does raise the issue of which values you are looking to make use of.
