Hi folks, HomeAssistant had a new release yesterday, and one of their new features is solar production forecasting (see here ). Which is some of those things that immediately gets my attention ... It is based on the https://forecast.solar cloud service, which offers a free and payable account (wit…

Hi Craig, If you look carefully at the dashboard pic I sent, you will see that I indeed turn on inductive motor loads. Obviously, these devices do not like frequent switching.... To overcome this, simply have the load turn on an "enable flag" at a safe SOC for your system(to allow a buffer), then p…

Yes, it's clear that we can't do On/Off, we have to do as in the air conditioning installations, do Integral-Derivative regulation. But it's out of my competence. Maybe we could use an ESP32-Cam with an AI to watch and analyze our sky on 180° ? :face_with_monocle: @eddee54455 Whoow :+1:

Hi @Jean-Luc , That would be an interesting solution, but not one that would be fully effective, I dont think... I have noticed that while clouds do make a large difference, the actual difference does not seem to be in proportion to what I see by eye... Edge effect of the clouds for one, seems to h…

Hey Ed, Nice explanation thanks. I have a whole of house energy monitor so it monitors my Solar, Mains and Consumption (3 phase) and shortly the 3 batery system i will be deploying. I have a 2nd one that monitors 14 of the circuits on my switchboard for most of my main loads - plus deployed tasmo…

I recall some earlier research on this topic... Staring at the Sun | IBM Research Blog

Hi @craigcurtin , The dishwasher I found quite easy to profile.... What mine does is as follows: Idle power - approx14W Fill - arond 30w, but Household pressure pumps come on as well. Emptying- Approx 50W Main pump - Around 130W Heating - Around 2kw The cycle ALWAYS runs in the following sequ…

Just for info, the Xiaomi sensor seems more accurate, in any case more sensitive and does not show saturation in high light. [image] Well it's a pity today it's not sunny so I don't know if it will saturate when there will be more light. To be continued. Below, comparison between the 2 sensors …

@Jean-Luc Re the sensors.... That's why I went the "micro panel" route.... All sensors I tried had different sensitivity/power curves and couldn't scale up accurately across the full range from 0 to fully solar lit... Some came close, but not good enough... The single panel (of the same substrate a…

That said, what you have achieved is very strong. Did you do all the logic with NR or are you using python or other tools ? I think @BartButenaers must be very interested in what you have done. He who is the originator of this topic Just a few questions: For powering the SonOff Pow, did you mou…

Hi JL, It works very well indeed, and I am very happy with it! All the major logic is done with NR, some of the Sonoffs are custom one offs I set up with ArduinoIDE, but most, by far, are Tasmota'd... The ones that I went to IDE I cant exactly remember, except for one near my mail server on the to…
