EAsun ISolar SMH 3K - gets the answer on one line about esphome-pipsolar HOT 15 CLOSED

I have replaced the RS-TTL converter, but the logs look the same

Is it possible that the ESP is corrupted and therefore not decoding the responses? Does the timeout mean that there is no complete response from the inverter after all?

Do I understand correctly that ESP should decode the inverter response and send it to the HA? If so, what's wrong with these logos? The inverter returns something wrong or maybe something is missing in the ESP?

I am asking for at least a hint.

from esphome-pipsolar.

The esp8266-test-protocols.yaml just sends requests/commands of different known protocols to your inverter and prints the responses to the log. This configuration should help you to identify the supported protocol(s) of you inverter.

• Protocol PI16: >>> QPI your inverter did respond with NAK (no acknowledge)
• Protocol PI17: >>> ^P003PI your inverter did respond with NAK (no acknowledge)
• Protocol PI18: >>> ^P005PI your inverter did respond with NAK (no acknowledge)
• Protocol PI30/PI30MAX/PI30REVO: >>> QPI your inverter did respond with NAK (no acknowledge)
• Protocol PI41: >>> QDI your inverter did respond with (230.0 50.0 0030 21.0 27.0 28.2 240040 0 0 0 0 1 0 0 0 1 1 0 0 1 0 27.0 0 0\xFC\xF2\r

It looks like your inverter responds properly to the PI41 protocol which is supported by pipsolar. Please use this configuration example as next step: https://github.com/syssi/esphome-pipsolar/blob/main/esp8266-example.yaml

And provide some additional debug output if it doesn't work out of the box. The component retrieves/requests periodically some data from the inverter and can publish the measurements a sensor values and controle entities via MQTT or using the native Home Assistant API.

One new thing is api.connection errno=11. This was not exist before.
However, still nothing is returned to the HA. All entities with ESP are inaccessible

from esphome-pipsolar.

I will check the QPIGS response tomorrow. It looks a bit suspicious because of the minus sign. It's possible pipsolar doesn't support this kind of response ((230.0 01.3 230.0 50.0 01.3 3000 2400 24.0 24.5 23.5 28.8 27.0 2 20 20 0 1 4 - 01 1 0 27.0 0 0) because it's special in some advance.

from esphome-pipsolar.

Then there is some hope that it will start working. However, I wonder about the answer for QPIRI "(226.0 50.0 226.0 50.0 0000 0000 000 393 25.04 000 033 0625 0000 000.0 25.00 00000 10010000 00 04 00000 000\x17O\r" because there is no minus sign, and yet it also generates a timeout. It is true that I found documentation communication over the RS232 interface, but for InfiniSolar there is a different amount of data in the response. Thank you for your help, because I didn't know where to look for the reason why something was not working, which theoretically should.

from esphome-pipsolar.

If it turns out that this will not work, is it possible to add individual fields from the response as entities in HA one by one?

from esphome-pipsolar.

Do you have access to the protocol description of your inverter?

I will ask the seller. He sent me a link to his surveillance software a few days ago, but I can't access it

Please set this line dummy_receiver: true to false. This should fix the timeout issues.

from esphome-pipsolar.

The protocol of your inverter is supported by the official pipsolar component of ESPHome. At the moment the dummy_receiver consumes the responses from the RX buffer and the pipsolar component is unable to receive/process the responses because they are stolen (by the dummy receiver).

It works! I am very grateful for your help. I didn't expect there could be a problem here, but I'm not very familiar with these protocols either. I think this will be a big tip for other users of these inverters with a similar problem.

I just realized the debug instructions at the README are wrong. I've fixed the instructions and extended the yaml configuration examples to avoid such trouble in future.

I have replaced the RS-TTL converter, but the logs look the same

Is it possible that the ESP is corrupted and therefore not decoding the responses? Does the timeout mean that there is no complete response from the inverter after all?

hello
I have a similar problem :(

Apparently my inverter does not support pipsolar protocols?
