[Feature Request] PVI idle mode #89

Open cwihne opened 1 month ago

cwihne commented 1 month ago

Autumn is here, autarky level gets impacted. S10E has a feature enabled putting PVI into sleep mode when battery is empty and no PV input to expect, e.g. in early morning hours before sundawn. I was trying to find out about PVI idle status, didn't find such in data transmitted to MQTT so far. Yet, I see RSCP tags TAG_PVI_DEVICE_STATE, TAG_PVI_SYSTEM_MODE or TAG_PVI_POWER_MODE which sound promising. I am monitoring those now by new raw queries. Maybe you have an idea which tag shows idle state of PVI and get it transmitted to MQTT?

Hi, I found the following tags in RscpTags.h that may be requesting the required state: TAG_PVI_REQ_STATE, TAG_PVI_REQ_SYSTEM_MODE. I hope you will find the right one and can let us know in this issue! Best regards Thomas

Here an intermediate result, still under surveillance: TAG_PVI_REQ_POWER_MODE seems to represent PVI's power state ON (1) or OFF (0) TAG_PVI_REQ_DEVICE_STATE creates sub-topics, most importantly TAG_PVI_DEVICE_CONNECTED (device available for service) and TAG_PVI_DEVICE_WORKING (device actively working).

Have to query specifically: ADD_NEW_REQUEST=TAG_PVI_REQ_DATA:TAG_PVI_INDEX:0-0 ADD_NEW_REQUEST=TAG_PVI_REQ_DATA:TAG_PVI_REQ_POWER_MODE-1 ADD_NEW_REQUEST=TAG_PVI_REQ_DATA:TAG_PVI_REQ_DEVICE_STATE-1

Overall E3DC system's own net power consumption for system operation is significantly influenced by PVI's activity. I continue investigating the flags and consumption. Btw. the RAW requests are not updated on forced update, they need a service restart to be re-sent.

yes, I get the following topics/payloads during discharging the battery this evening: e3dc/raw/TAG_PVI_DATA/TAG_PVI_POWER_MODE 1 e3dc/raw/TAG_PVI_DATA/TAG_PVI_DEVICE_STATE/TAG_PVI_DEVICE_CONNECTED true e3dc/raw/TAG_PVI_DATA/TAG_PVI_DEVICE_STATE/TAG_PVI_DEVICE_WORKING true e3dc/raw/TAG_PVI_DATA/TAG_PVI_DEVICE_STATE/TAG_PVI_DEVICE_IN_SERVICE false

RAW topics will be send only for changed payloads, "force" doesn't change the behaviour for the RAW stuff... so that's like it was (badly) progammed :-)

Best regards Thomas
