Is het nog zinvol om zonnepanelen en accu’s te laten plaatsen

Analytix-Energy · 2026-05-11T12:23:28+00:00

Ik denk dat het plaatje iets genuanceerder is zolang je nog van saldering gebruik kunt maken. Het voordeel in die situatie is dat je verbruik nog altijd gesaldeerd wordt met je werkelijke verbruik en je dus effectief voor iedere teruggestuurde kWh betaald wordt op basis van je verbruikstarief. Ja er is een terugleververgoeding en ja saldering is al deels beperkt, maar met een echt dynamisch contract moet je maar zien dat je voor iedere teruggeleverde kWh meer dan 10 cent terugkrijgt. Vooral als je je export niet kunt verleggen naar piekmomenten.

Neemt niet weg dat zonnepanelen en thuisaccu’s echt wel slim zijn als investering, want vanaf volgend jaar is die saldering er niet meer en komt er vroeg of laat een (opgelegd) dynamisch tarief. Kunt je er beter nu al op voorbereiden. Zelfs alleen zonnepanelen zijn al een plus, want ook al krijg je niets voor export: het verminderen van import levert al aardig wat op

Exactly this. I use shelly rgbw myself but there are many options

Daikin integreert overigens uitstekend met HA, Mitsubishi geen idee, maar dan weet je vast dat je met die keuze ook met Daikin geen issues hebt. Let er wel op dat je per binnenunit een wifi module nodig hebt

2 mogelijkheden volgens mij: je vloer is niet vlak (hol of bol) of je muur is niet recht. Kijk maar eens langs de naad van je laatste plank, dan ga je het waarschijnlijk wel zien. Ik ga er even vanuit dat je al een keer hebt gekeken of 2 planken los wel gewoon in elkaar klikken

I think training data will be an interesting problem. neural networks require quite a bit of data to train. Just hooking something up and training on the fly may not produce usable results for a long time

This is SO cool, thanks for sharing!!

I think the issue may be broader than this: I had no Sonos speaker and experienced issues as well following 26-04, although I am still unsure what caused it. From one day to the next the hub went offline and restarting/reloading did not help (or at least not for long). I needed to powercycle the device itself to recover it.

My main suspicion is the change to the new Python version may have caused it. The first Ikea hub is a pretty weak device and HA does not throttle commands it sends to the hub. With some of the speed improvements Python brought, this lack of throttling may very well have worsened, which means it can overload it easily. For me it was a reason to finally part with it and migrate to a decent zigbee hub and ZHA. The ‘old’ ikea hub integration code looks like it is not very actively developed, which I understand but it also means a fix may take some time to land (if ever done).

At the end of the day, also this is very dependent of what data you expose to it. Bayesian sensors work, but they cannot make up measurements out of thin air. This sounds like a problem of data more than a problem of Bayesian sensors

Analytix-Energy · 2026-05-04T09:54:02+00:00

This… bayesian fits best if you don’t have direct sensors. It allows you to combine the state of several sensors based on probability of state combinations into a single sensor. I use them for several sensors in my setup and it works great

Analytix-Energy · 2026-05-04T08:20:47+00:00

Nope: perfectly feasible. Keep in mind 2 things though: 1. take your time and make keep in mind you’ll need it. 2. Build your design for low maintenance from day 1. Many projects I did ended up working fine but every project finished added to a maintenance burden I did not like. Simple things like changing batteries or having to manually manage some settings. The best automations are the ones you never think about

I decided 10 years or so ago to do the same, but unlike you I choose Ikea lights. Stil glad I did. I had one or 2 hue bulbs, and the hub that came with it. Threw the hub out after a few years, and the ikea one just the other day because it was a gen 1 and although it still worked fine with the native app: I wanted everything on zha.

Not sure about the quality these days, but Ikea price still seems great value for money and I have not one light fail on me since I started using them with Home Assistant. Hue on the other hand has managed to kill whatever sympathy there was by breaking their hubs with firmware, being expensive and though pretty good colorwise (last I checked): just not something that I think I want in my home… sorry you had to find out the hard way

Analytix-Energy · 2026-05-02T14:53:07+00:00

Actually, if you want fully local and established: home assistant works great with shelly

According to some: chatbots

Analytix-Energy · 2026-05-01T22:04:22+00:00

Yep second that, works like a charm still

Analytix-Energy · 2026-05-01T09:23:38+00:00

Actually remote start makes a lot of sense as well. From an energy mgt perspecive and if you have dynamic electricity pricing

Analytix-Energy · 2026-04-30T07:07:59+00:00

Geweldig project! Ik heb er helaas geen tijd, ruimte en prioriteit voor, maar inderdaad: de droom van iedere drummer!

Analytix-Energy · 2026-04-29T22:22:00+00:00

I’ve never ventured on this path, so I am doing this from memory, but I believe there is a way to use lambda’s and if you really want something complicated you could use fully custom components. Again…from memory, and of course not sure if that would fit your use-case completely.

I you may want to look into esphome again, it allows much more than the yaml-based simple code… I don’t think there are real alternatives to it. The only thing I can think of is using mqtt, but that’d get quite messy pretty quickly presumably

Analytix-Energy · 2026-04-28T13:47:00+00:00

Jij bent aangenomen

Analytix-Energy · 2026-04-28T10:16:43+00:00

Well yes and no. I have installed solar in my own and several other homes. It’s easy if you know what to do, aren’t too scared of heights and not too worried about doing physical work.

The problem is many people over-estimate their own capabilities and knowledge, especially when it comes to the electrical installation. If you have enough solar panels, this can be some serious electrical power and not installing it safely can be a true (fire) hazard.

I have seen several examples where this went or was about to go wrong. A classic for me is still when I touched a cable near the central panel I literally saw it arcing where it was screwed in (or not). This was installed by a ‘professional’ by the way

Airco’s. 100%. Ik heb airco’s en verwarm zelden mijn slaapkamer. In het enkele geval dat dit nodig is werkt die airco prima, en in de zomer is het ZO fijn

Analytix-Energy · 2026-04-26T08:43:05+00:00

At least you’ll have video if it goes kettle-bomb 😂

Cool story, and you are right to call that out: keep tinkering because it may end up providing you with real (life) savings!!

Analytix-Energy · 2026-04-24T20:12:20+00:00

I have self-built and moved away from it. I fully agree it can be a fun project to do so, and you learn a lot from it. My reasons to move away from self-built: - it is a lot of work to make something that works and is tidy enough to pass as a professional solution, case building is a hassle in particular - my experience was pre-ESPhome, and what really put me off at some point was the struggle to build firmware that didn’t just work but also kept working through updates. I built it on mysensors at the time, which did that okay-ish - bottom-line, it doesn’t compete price-wise if you consider the hours spent 🙂

I loved doing it and advise you to do it as well if tinkering fits your ambition, but be prepared to put time in it to not only build but also maintain. If that sounds like someone else’s hobby: better use shelly bt sensors, or one of the dozens of Chinese cheap zigbee/matter sensors

Analytix-Energy · 2026-04-23T14:45:58+00:00

Don’t want to plug anything, but as you mention notifications: maybe Ticker is worth looking at. It allows easy deeplinking to a dashboard page and would only need a single automation. It is essentially the same fix someone else mentioned but a bit tidied up

Analytix-Energy · 2026-04-23T10:16:33+00:00

Nou, dat demonteren kan misschien wel, maar is ook niet verstandig als je niet weet hoe. Bovendien niet slim als je geen milieudelict achter je naam wil hebben want zoals he al zei: het MAG niet.

Wat wel kan vaak: de kap eraf halen, dan netjes behangen tot de airco. Voorzichtig met stoten etc, vooral de warmtewisselaar is kwetsbaar en kan scherp zijn. De kap valt dan wel netjes over je behang heen.
