  "notes": "FoxESS Avocado and its rebadges MQ2200, Solakon ONE and Tepto Avocado Pro are a PV-coupled balcony/home storage unit. Source: the evcc meter template https://raw.githubusercontent.com/evcc-io/evcc/master/templates/definition/meter/fox-ess-avocado.yaml, used as a secondary source; no FoxESS register document was retrieved. The template offers RS-485 and TCP access with unit ID 1 and states 9600 baud for the serial path; this seed records the TCP path (port 502, unit ID 1), which is the one that does not need the RS-485 framing the template leaves unstated. All values are holding registers, the meter block 39123-39131 is read in one request, and the 46xxx block is the battery's remote-control interface the template writes for battery control. FoxESS sells a separate H3 hybrid line with a completely different map (see the fox-ess-h3 and fox-ess-h3-pro-smart seeds); this file is not a rebadge of those. The template does not publish battery voltage/current, temperatures or per-MPPT PV values for this product, so they are absent rather than guessed."
