Some sensors doesn't show valid values (Axpert VM IV 24v 3600w)

[Pokornypetr]

hello, the data from the converter is working, most of the values ​​look ok. Some problems are what I encountered with the values ​​I really need. I do not see the current power of the PV panel and the current voltage of the PV PANEL pv_input_voltage: has a value of 0v - 0,9v at an almost real 180v pv_charging_power: it is still at 0w

pv_charging_power: name: "FV nabíjecí výkon - ${friendly_name}" id: pv_charging_power pv_input_voltage: name: "FV napětí - ${friendly_name}"

Could you enable the debug output of the uart and provide some logs including the raw traffic of your inverter (at a sunny day)?

as I said, most of the data are ok, only pv charging power and pv voltage do not match or are without value.

QPIGS: (247.3 50.0 239.0 50.0 0931 0805 025 360 26.10 007 060 0017 04.6 179.2 00.00 00001 00010110 00 00 00831 011

so can I ask for some concrete advice. I'm a big llama so I really need a deeper explanation

although I don't know which values ​​in QPIGS, QPIRI are fv voltage and fv power, so I would say according to the numbers in the log that they are loaded, so why doesn't it assign them to the pv_charging_power values: pv_input_voltage: -?

Please update your external_components section to:

external_components:
  - source: github://syssi/esphome-pipsolar@2424mse1
    refresh: 0s

and flash your ESP again. The 2424mse1 feature branch should fit better to your inverter. I assume this will solve your issue.

[Pokornypetr]

In external_component, everything was listed as you wrote in the example, so I only put reload-groups, but nothing changed, the problem is still the same

I assume this will solve your issue. can I ask for advice, in external_components everything is as it should be according to the photo, I probably played ESP again to be sure, but the problem is the same. what more can i do

Peter, did you resolve this discrepancy? I have the same inverter (AXPERT VM IV 48V) and the data you are talking about are displayed in the wrong format too.

[Pokornypetr]

Hi, sorry I haven't been here for a while. Unfortunately, I haven't been able to solve it yet. Some items could be extracted from other values, I have the impression that the voltage on the PV panels comes from the value of the battery voltage from the scc, others, I don't know yet. I would like to finish it successfully, but I don't have time for it now and I don't know how to do it myself. and the support is silent here :(

[syssi]

@Pokornypetr Let's give it another try. Providing support is time consuming.

Could you tell me the names of the sensor which doesn't provide the correct measurements / values? Do you own the protocol description of your inverter or could you ask the seller to provide one?

[syssi]

• pv_input_voltage: has a value of 0v - 0,9v at an almost real 180v
• pv_charging_power: it is still at 0w

Hello, thanks, pisolar was updated some time ago and since then everything shows as it should even on an expert. Many thanks for your work!

Summary: Trying to parse an float as integer was probably the root cause or increasing the RX buffer did the trick.
