I have completed and testing my unit now, it took two orders due to an issue with the first but here is the final unit and it works well. for more pictures and code check the link https://github.com/shanekuz/SPANETMCU it includes the gerber files so you can just order on line.

Matt-NZ if you PM me and are in NZ i will post you one of my boards as i had 5 printed. You shouldn't run the power from the SPA to the nodemcu no they are not made to run on that voltage.

@shanekuz that looks very snazzy, very generous of you. I can arrange a courier pickup if thats easier. Will contact you via linkedin.

I have managed to get it all working after a false start, currently powering on battery until my buck converter arrives I posted on wayne-love's page here wayne-love/ESPySpa#1 (reply in thread) might help other noobs.

This is extremely interesting! I have a new Alpine spa here in New Zealand and I do a lot of playing with NodeMCU. I would love to integrate my spa into OpenHAB at my place. @shanekuz you are doing great work! If you have any more of your PCBs, I would gladly take one to accelerate my ability to contribute back to the project.

I can't find a way to PM you @shanekuz - I'm based in Palmerston North and very keen to get involved. My email is [email protected] - please reach out! Thanks.

Sorry for the spam messages - I've been digesting everything I can find on this topic for the last while, and working out how I will proceed. I have another question - is it time for some of these projects to join forces, so that we are not independently developing multiple implementations of the same base code? In my day job as a hand-waving software architect, bringing together distinct teams is what I do, and I feel like there are at least two very similar projects here (belonging to @shanekuz here https://github.com/shanekuz/SPANETMCU and @wayne-love here https://github.com/wayne-love/sn_esp32).

I'm happy to help facilitate however I can, e.g. work on getting started docs, helping to unify and improve code, introducing a central discussion system (discord, GitHub discussions, etc).

@JonathanGiles welcome to the party! Agree, it would be better if we could merge the 2 projects. The only reason that I started deving on the esp32 is that I had one lying around doing nothing. To migrate to something like the NodeMCU would be largely a cut and paste process, with some minor changes along the way. I'm going to be the first to say that my code is not pretty and is in dire need of refactoring.

I'm not a big discord user, but I think it is what all the cool kids are using? I'm happy to set one up, but I'm also not going to be the guy that arrives late and forces my will onto a project. If it'll help I can look into setting it up today. Then we can arrange further what we want to do...

I've taken the liberty of creating a discord here: https://discord.gg/faK8Ag4wHn

I'm happy to grant permissions as appropriate.... And I selfishly want to get help so I can get parts ordered from @shanekuz

@JonathanGiles I ordered 5 PCBs of @shanekuz's design, I can mail you one. Also have the power bucks in stock too if needed. Will join your discord to get an address

Hi Blake, can you please advise how to obtain the API key? I didn't see anything obvious, assume I may need to inspect the traffic.
Not as smart as you guys, so really just thinking of a basic Python script to change the spa into away mode when Solar generation is low.
Just had a massive power bill, after someone (myself) left the temp set way to high during winter...:)
I am now better using the "sleep mode" to avoid heating at night.

Hi This is an embarrassing question but how do you program this into an esp?

I use the arduino application

Excuse my ignorance but I have it but don't really know how to do it as it can only open .ino files and I can't find any.

I use VSS but if you google change from VSS to Arduino its pretty much just a file name change to .ino i think.

ok so you mean i can basically rename master.cpp to .ino?

Yes I think so, give it a go

Hi Tried but it's too hard for me as I get loads of errors all the time.
