    Home Assistant & Heat Pump (Smart Life application)

    I have an ITS-5.4HD heat pump with Wi-Fi but was only able to integrate 2 variables from the Tuya app. With some research and reverse engineering, I have now successfully integrated the heat pump via Modbus into Home Assistant. The integration makes all the temperature variables, stop/run...

    Lasik eye surgery, should I do it?

    Had both eyes done back in 1999 by Mr Percy Amoils when his rooms were still in Sandton. Apart from the initial post-op discomfort due to the dilation of the pupils and the focus returning after 2-3 days, I had no issues. I had to provide an ophthalmic report on both my eyes in 2020 due to the...

    Conflicting stories around solar panels

    PV Watts remains the same irrespective of how you connect the panels together (3Sx4P or 2Sx6P). Two decision you need to make: (1) how much PV Watts you want/need/can afford/have space for on the roof and (2) what MPPT will you need to convert the PV power to usable charge energy. Sinbad has...

    Generator or Inverter for residential use?

    I think it is important to add that ESS is implemeted in the Color Control GX or Venus GX device and not the inverter. Most Multiplus and Quatttro Inverters can do ESS, but require the GX control unit. There are also various "assistants" (Victron's name for small subroutines or applications)...

    Generator or Inverter for residential use?

    Speedster, depending on your Depth of discharge on the 10 kWh lithiums you might need more PV for a full charge+running additional loads (like the pool pump) I have 2.5 kW PV on the roof, 2x US3000 Pylontechs and only cycle them to 50% DoD (3.5 kWH per day) (keeping spare capacity for load...

    So BP petrol is really bad

    Not really aligned with the OP's issues but some gen on the ethanol; apart from the information as shared by geezer, one of the big limitations on Ethanol in petrol is the transfer pipeline specifications.
