Custom HVAC Wi-Fi zoning

3D prints, Arduino, NodeJS, Electronics, MQTT, HomeAssistant, …

Hi to the community.

It’s been quite a while now I’ve developed my custom heatpump HVAC zoning system using custom made thermostats
(based on Wemos D1 mini - ESP8266)

The two main goals of this approach where :

  1. Cost saving (total installation made by my own ~3k€ compared to fully made by local artisan ~11k€)

  2. Wanted to learn new stuff. I’m a software developer (javascript) and I wanted to learn some hardware skills, to be able to add custom made IoT in my whole house (which I’m renovating since 3yrs)

If in any case, this can be useful to someone, I’d be glad about it, that’s why I share this project in here.

Here is the Gitlab repository of the project : https://gitlab.com/ghyslainbruno/zoning

It’s quite complete, at least for my personal use (I’m using it in “production” for 2 years now), even if I took some shortcuts (as we always do in POC developments).

PS:

  • Please, keep in mind that hardware (design and so on) is not my job, so I apologize if things are not done how it should be.
  • Also, It’s my first post in here, so I’m really sorry if I don’t respect some rules, I’d be glad to change things if it’s the case.

Very interesting. Interested in the thermostats. I’ll Look into it

Hi @wrongisthenwright and thanks.

I planned to make the thermostats code more generic (wifi credentials, mqtt credentials, hysteresis thresholds etc), let me know if this is something that might be interesting to you.
