Saving heating costs with OilFox - is that possible?

hello dear ones,

I come from beautiful Thuringia and we heat our apartment with oil. Recently, you received flyers from OilFox (.io) in our pedestrian zone. They also have a YouTube video. Just search for OilFox.
It is a device that clamps onto your oil tank and measures the oil level for you. When the tank is empty and the oil price is favorable, you can order via app. According to the website, you can save up to 700 euros.

My question: is there something similar already? Because so far I haven't found any similar products on the internet. Although the whole thing already looks quite finished.

Best regards, Squirrel

I still know the analog version of the OilFox - a person goes to the oil tank, measures the oil level, calls the suppliers they know, and then saves up to €700

Online, I just found an OilFox that can do magic. It changes the surface tension, combustion, etc. - such a bummer that I have a heat pump. There is probably the WPFox for that - it lets the brine and electricity flow more freely

I would order oil now. It is as cheap as it hasn't been in 10 years. Simply watch the market yourself and regularly check the level of the tank.

To make the chaos perfect, I would still wait, unless the tank is completely empty.
The prices are still falling further.

What is a Fuzo?

I find the advertising "Tank empty/Prices cheap" stupid, when the tank is empty, it's too late.

Pedestrian zone?
