I work in the industry making hardware and software for large scale commercial and grid scale storage.
There are several challenges with this, safety, thermal runaway, and life cycle of the asset which has a limited amount of cycles.
Also the architecture of the system for the AC inverters and the DC side can come from very different places in the supply chain and aren’t as vertically integrated leaving you in a position where you can’t actually make this work without compromising something in the supply chain. That being said we are talking about a LOT of energy in these systems and to dissipate that much heat you’d need a load bank.
Cool. We have worked with a customer on this exact thing and deployed an edge and cloud controller that orchestrates control changes based on the all the turbines. Such a great project!
Lost my 635 day streak last week, offered £5.99 or something to repair it. I was pretty gutted but actually on reflection, the gamification just added undue stress. Duolingo is great for vocab and repetition, it was only with a tutor that I really became conversational.
Also agree. However, I do yearn to relive the days where one can load up a web page and start reading content, without being jarred by pop-ups and ads that inadvertently move the content post load (which of course happens 3 seconds later..).
I know a site, it's on mobile. You use it by entering a location in a search bar.
You select the search bar, the keyboard takes a second to appear. You start typing, nothing happens because they've reimplemented the text box in javascript, and the script hasn't fully loaded yet. The script loads and the second half of the letters you typed appears in a letter by letter fashion. The page freezes and a suggestion box appears, every second or so the suggestions change to reflect the letters you typed earlier. You erase what you've typed. With every letter that changes, the page freezes a second as a new suggestion loads. When it freezes, it stops accepting letters, so there's a lot of erasing and re-typing. Alright, you're almost done typing... then the page freezes and the page turns grey, and a pop over loads. They want you to load fill out a satisfaction survey. You try to close it to continue, but the script handling the close button hasn't loaded yet so it doesn't work for a good 20 seconds.
If you want a picture of the future, imagine a javascript stomping on a human face -- for ever.
This accurately describes my experience using Google Search on Google Chrome on a Google Pixel 5 running the latest version of Google Android (for good measure, using Gboard). It baffles me that for a long time I couldn't even select text in the search bar without something going so wrong that my phone ground to a halt and had to soft reboot.
There was an article posted here [1] a few weeks ago called I Don’t Like Computers which had the same nostalgic vibe about computing in the past and I argue it boils down to loss of control. End users used to be in charge. We used to be in the driver’s seat. We used to tell computers what to do. Now, with pop-ups, ads, notifications, and so on, they tell us what we should be doing and we have to beg and work around them to do what we want. “Where do you want to go today?” is long dead.
Honestly, the end user should be subsidised for hosting this feature. The fact that Amazon are able to spin this as "we're giving this to you for free" shows how far the tech industry has gone in tricking it's consumers into thinking that they're getting something for nothing.
We too are also doing something similar. We've just started the move to timescale for real-time energy and sensor data from industrial assets. We have a single customer with about 10TB of data and growing from 2 years worth of real-time monitoring which is stored in a mixture of table storage and SQL. Timescale on PG seems like blessing for our future plans :)
There is definitely a need for better technology for start-ups in this space.
Having said this, I don't know what this product does from the website.
We pay ~$80 a month for 2 users to a financial planning application that integrates with our accounts (Xero) and it works well. Our revenue is 7 digits annually.
As a start-up founder, I appreciate what you're trying to do with your model but I kind of like, you know, just knowing the fixed costs regardless of our revenue.
[Not OP] Depending on your needs, Fathom[1] might work if you are on a tight budget. Summit[2] has also been building quickly in this space but I haven't tried building a full model to see how the "event-based" pricing scales.
Just a LoRa gateway without the WAN stack? There are usb serial devices for 20-30 pounds, you can use a raspberry pi with them for a cheap gateway. We’ve used some for development and testing. https://www.st.com/en/evaluation-tools/b-l072z-lrwan1.html
There’s a few layers to this. You’re completely correct that you can use those boards for LoRa without LoRaWAN. I think what OP is looking for, though, is cheap LoRaWAN gateways that aren’t tied to The Things Network. Can’t use the SX1276 for that, since it can only time one receive frequency at a time.
There’s cheap gateways available that are hard-coded to talk to TTN, and there’s expensive gateways available that let you run a private WAN. There just doesn’t seem to be cheap gateways available to run a private WAN.
I have read rumors of alternate firmware to allow that hardware to work outside TTN but haven’t chased it down myself, so mine is running as a TTN node right now.
You’re looking at around $150 for an 8-channel base node. The single channel at a time nodes (like the SX1276 in the one you linked) “work” but with significant limitations compared to the $150-500 8-channel gateways.
