SolaX Inverter Modbus

The Growatt MOD 8000TL3-HU reports a serial number starting with `DMS` from holding register 3001. Since this prefix was not recognized, detection fell back to register 9, read the firmware version instead, and rejected the inverter. This adds the `DMS` prefix as `HYBRID | GEN4 | X3 | MPPT3`. A regression test covers the reported serial and firmware values. Fixes #2146

Summary - Recognize Growatt inverters with serial prefix `SZG` and firmware prefix `TJ1` (e.g. serial `SZGDCL505K`, firmware `TJ1.0`). - Map both to `PV | GEN2 | X3` (3-phase PV, 2 MPPT), matching the local fix that cleared the `unrecognized Growatt inverter type` error. - Fixes #2261. ## Test plan - [ ] With an SZG / TJ1 Growatt on Modbus, confirm setup no longer logs unrecognized inverter type - [ ] Confirm 3-phase PV entities populate (grid L1/L2/L3, PV1/PV2 strings) - [ ] Review that classification as GEN2 remains appropriate if a named nameplate model is confirmed later Made with Cursor

Bug Description After updating to `2026.05.2`, `sensor.pv_power_total` returns a constant 1W on a SolaX X1-VAST inverter. The individual string sensors (`pv_power_1`, `pv_power_2`) continue to work correctly. ## Root Cause Commit `fc0a7ee` changed `pv_power_total` from a calculated sum of string sensors to reading Modbus register `0x32` directly, with support limited to `HYBRID | GEN6` (with a note that *"GEN5 testing needed"*). On the X1-VAST, register `0x32` returns a constant 1W, it either does not exist or maps to a different value on this hardware. Prior to this commit, `pv_power_total` …

These should share the same register map as the existing inverters. Simply add model ID decoding for them to ensure the correct HYBRID/MPPT/X3 flags are set. This also corrects the MPPT decoding for inverters in the 30/31 high byte ID group. Fixes #2158. --- Furthermore this include a more complete population of the energy dashboard mappings. The dashboard mappings have been in a draft PR for a while. They've been added into this PR to allow testing alongside the new models and get them merged in.

Summary Adds a dedicated `plugin_viessmann` for Viessmann Hybrid Inverter B1 devices using the GoodWe-compatible Modbus register map. The implementation was validated with a Viessmann HINV6.0-B1 through Modbus TCP, using holding registers and Modbus device address 247. ## Changes - Adds sensors for PV, grid, load, battery, BMS, operating state, temperatures, voltages and power. - Uses meter registers `36015` and `36017` for cumulative grid export and import energy. - Adds a reusable daily-delta energy sensor which calculates daily import/export from the cumulative meter totals, persists its …

Description ### Environment - Home Assistant: 2026.06.7 - SolaX Modbus: 2026.7.0 - Inverter: Solinteg M2HT-50K-150 ### Description While integrating my Solinteg inverter, I noticed that Battery SOC is defined in `plugin_solinteg.py`: - key: `battery_soc` - register: `33000` The debug log shows that the holding register block containing register 33000 is read successfully. However, no Battery SOC entity is created in Home Assistant. I verified that: - the entity does not exist - the entity is not disabled - communication with the inverter works correctly - Battery Power is available - other …

Describe the bug After a firmware update, my Pocket WiFi+LAN dongle stopped serving Modbus TCP. Port 502 still accepts connections but never answers, no reply to MBAP or RTU framing, on either of the dongle's two interfaces, before or after a reboot. The dongle is otherwise healthy: cloud reporting works and its local web UI is fully responsive. The new firmware replaces the server with "Direct connection to third-party platforms", which reverses the direction, the dongle connects out to a host you configure and speaks ordinary MBAP-framed Modbus TCP over that outbound socket. Send a normal …
