Raspberry Pi Pico Home Temperature Monitoring System with Node-RED

[@ddjazz]

Nice project , you could do the remote sensor with just an esp8266 with easy deepsleep needing only 20 to 100uA while in deepsleep. ESP.deepsleep(60e6) sleeps for 1 minute. No pico needed. Running for several mos on a small lipo. ( depends how frequent and how long it takes to send your data over wifi)

This would be a good way to find cold spots or drafts in a house. That's much more important on my side of the pond. Canadian winters can be brutal.

I did something very similar as an experiment, using a Pi 3A+, some Pimoroni breakout sensor boards, AWS IoT (as the MQTT broker) and hosted a python based dashboard (Dash Daq) for the visualisations on AWS Elastic Beanstalk. Was also able to do the dashboard locally via local host, but initially wanted to see if the readings/graphs etc could be accessed via the internet.

I wanted to host the dashboard locally, no need for it to be in the cloud. There are many off the shelf solutions in the cloud or the MING stack would also work on a cloud provider.

Spotted the parts is missing the temperature sensor. I used a DHT11 but there a wide range of sensors you could use

[@chrisE815]

So that's the sensor he's using?

[@chrisw1462]

Where'd you get the DHT module? Certainly wasn't included in the Parts list at the beginning. Good work...

Really interesting project and very nicely produced video. AND I understand adding a harddrive to a PI would require its own video. I tried looking for it, and search for "PI with hard drive ATX power supply", that video didn't jump to the top of the list. The search results said ~26,000 results! Can someone please post a link? Thanks!

[@Workshopshed]

The harddisk attached to the Pi via a USB to SATA adapter and should "just appear". The other video explains setting up the permission etc to make it work with the MING stack. The link is in the description, the video is on the E14 community

Is it possible to connect the raspberry pi straight to a node app with a react frontend to simplify the stack? Has anyone tried this?

[@jerzykaltenberg298]

How are you connecting the esp8266 to the pico ? a wiring diagram and link to code would come in handy. Also, what code is running on the esp8266?

[@Workshopshed]

Hi Jerry, the code for the ESP-01 is the standard firmware that comes with those, is called ESP-AT. The wiring diagram is on GitHub the link is via the E14 community link in the description. I don't seem to be able to add links in the comments.

Neat project, but the lack of Raspberry Pi availability is a BIG hurdle right now.

[@em21701]

ESP32 is a better choice for the sensor array and they're in stock at several suppliers.

[@Workshopshed]

@@em21701 At the time of planning ESP32 were a bit hard to come by, but I have seen them since and yes a simpler option.

[@Workshopshed]

The MING stack could be run on other hardware or even in the cloud.
