SMUSHI is another demo of the HeaterMeter client library, now with ESP32 support. I needed to make sure the client library worked on ESP32 and all the test devices I have are already doing something so I bought one of these LILYGO(R) TTGO T-Display ESP32 mouthfuls with 1.18" IPS TFT display...

EDIT: This affects both AP and Client mode on Pi3B+, but AP mode is more consistently broken. Only remedy is to switch to 5.8GHz wifi or lower 2.4GHz output power to 10dBm if you can. details I've been doing some experimentation on the bench with a HeaterMeter 4.3.4 and a Pi 3B+ and I'm seeing...

A long time ago someone had an idea to make a giant 7-segment LED display panel that showed the temperatures from their HeaterMeter in a standalone unit. They never did, and after I priced checked bigger LEDs ($3-5 per digit) I cheaped out and didn't want to make one either. I still had it in...

We've all been on Snapshots so long we completely forgot we could do releases too. It has been over 3 years since the last stable release but that hasn't meant that nothing has been going on, there have been 104 files changed, 8348 insertions, 4477 deletions since the last release. In that time...

How many times have you been so excited to eat delicious smoked meats that you've forgotten to stash / archive the database? Never? Well... I guess that's fine too, but now HeaterMeter will automatically stash databases for you! If you've never visited the Archive page, or don't have any idea...

I've been working on a new upgraded feature for the past week and I thought I'd put out a little preview as what's in store because I'm tired of looking at the code for today. This is not available in the snapshot yet (pending UI changes) but look for it to be available after Thanksgiving. Don't...

I built this Adapt-a-Damper a year or two ago for testing purposes and it has sat on my workbench since then because I have mas muchos damperos. If anyone wants it I will even pay to ship it to you, but only to a United States address. It has the blower, servo, RJ45 installed, and with a...

Hi folks, it's-a me, the HeaterMeter guy! First off, I'd like to take a moment to express my utmost gratitude to the community here who has been doing a wonderful job of supporting new HeaterMeter users and helping them to troubleshoot their builds and answering their questions. I am so...

I spent half the day today moving over hosting from the existing service in Miami to Amazon Web Services in Virginia. I think everything is back up now so if any of the heatermeter downloads don't work or the device registry isn't working, let me know and I can look into it. For those keeping...

Today the Raspberry Pi foundation released yet another Pi B, this time they at least incremented the version number to 4! This new board has an entirely new SoC and is not supported by the HeaterMeter software. The layout changes to the design also mean it is physically incompatible with both...

The Pi Foundation has released an updated model A! It is a Pi Model 3 B+ except without the Ethernet and only one USB port 1.4GHz 64-bit quad-core ARM Cortex-A53 CPU 512MB LPDDR2 SDRAM Dual-band 802.11ac wireless LAN and Bluetooth 4.2/BLE They are currently available for $25 and again I am...

A few years back I got fed up with critters eating all my peppers in the garden so I started growing them indoors with a grow light to much success. You know I can't have anything without covering it in sensors and electronics so obviously the whole thing is now monitored and controlled within...

On Monday Oct-8 2018, the server that runs heatermeter.com for the firmware downloads and images is going to be migrated from the VPS hosting in Atlanta to Miami due to the provider I use closing down that location soon. The new location means a new IPv4 address as well. We're all backed up and...

It's probably hard to keep up with how many protectionist tariffs are being slapped on every country and product these days, but one in particular is going to impact new HeaterMeter builds. Starting on Friday, July 6th, the US will impose a 25% tariff on electronic components manufactured in...

Happy Pi Day everyone! Today, the Pi foundation released a new revision of the Raspberry Pi 3. No versions of HeaterMeter support the 2018 1.4GHz Pi 3 Model B+ Physically, the design is compatible with the HeaterMeter 4.3, but there is no software support yet. I'll have to get my hands on one...

I've been messing around with some UI ideas and while we can all agree what a blower or fan icon looks like, I keep struggling with what sort of icon would represent the damper's position. The biggest problem is that I am not an artist, but the other problem is that the icon needs to be easily...

NOTE: It is suggested to run the SNAPSHOT firmware and not the v14 release. The snapshot has bugfixes and support for Pi 3B+ and is just as stable. It has been a year and a half since the v13 release (March 23, 2016) and I think we're finally ready for something new for both v4.2 and v4.3...

I'm sure you've all been waiting anxiously since Monday's security disclosure about dnsmasq's many Critical and Important security vulnerabilities. These are remotely exploitable issues and some allow malicious code execution. While the majority of Internet of Things devices (any smart device...

I've tried a few different ways of making some mounting holes in the 4.3 case. There's not enough room between the case bottom and Pi for fully enclosed spaces without making the case another 1mm taller just to support it. I've sort of compromised and came up with these instead. What's...

I've added YouTube videos to the wiki that show the entire build process of a 4.3 HeaterMeter in all boring detail. There's not much to it except staring down at a green PCB with parts going into it as I struggle to talk and solder at the same time. People have asked for it though so maybe it...
