You'd probably be able to tell if it was working with a multimeter. At least on mine, you can tell there's a signal going through once a second when it updates because the voltage jumps. You can test on both sides (the LCD side and the shift register side) to detect a break too.

Yeah D7 should only connect to D7. B+ is just 5V so if the bare trace is giving you a problem, you can just cut the trace further back and run a wire to bring 5V to B+. If you're seeing that leg of the BS170 as connected to that pin, that's GND, so you've likely got some of the ground fill pour...

Yeah you can use D8 to run another Data line and bridge the clock, 5V, and GND from the others to add another module. There is some sort of limit on how many you can gang together, because they all have pullup resistors on the lines so each one added in parallel reduces the pullup resistor so it...

I've got to apologize if that's how I made you feel, I was just explaining why I didn't include that myself. You took what I started and got into it and made it do what you want, which is what the whole HeaterMeter project is all about! I may be a little old programmer salty about IoT wifi...

Yeah I loved my Pebble and uhhh whatever the second Pebble was called. I was sad that they weren't able to stay in business after they were such innovators in the market. I don't think either of the iOS apps have been updated in years and I can't even remember who developed them it as been so...

Yeah I've used WifiManager many times, and I know that this is the standard for IoT device setup, but I can't tell you how many hundreds of posts and emails I've answered about confusion trying to connect to the AP's captive portal to configure the wifi. That's why there's like 800 ways to...

Haha I thought this was a typo of "companion" or something but holy cow they really are called complications. There is a Home Assistant setup I've seen for pulling data from the MQTT stream, so sounds like that would work. MQTT isn't very well integrated into the webui yet, but I hear it works...

I'm aware of wifimanager, but I didn't use it because that's how HeaterMeter's wifi used to be and a vocal majority seemed to not understand the concept of connecting to an AP to configure it. It wasn't helped by Android silently switching off the wifi if it determined that there was no Internet...

Yes, boss man! That's why there was a Pebble app! It was awesome to be able to just look at your wrist and see what's going on. Does the Apple Watch actually let you do stuff and draw on the screen? It seemed most wearables were leaning away from that and just going to 1st party only apps...

You can start by going into the LCD menu on the device itself and going into the diagnostics with the blower in Voltage mode at 100% output. Scroll right until you get to "Manual Mode" then HOLD left until the display switches to a bunch of numbers (Pit probe diagnostics). Release the left...

So numbers twice the size they are in the Lo-Fi Home? That's not much different than what we've got already. I wouldn't add the High/Low/Max/Min for sure, that's some useless info. I'd also be wary of making something look too much like a commercial product. "But it is just a list of a few...

There we go! Good work getting through it. I'll admit it isn't an easy set of steps but I really didn't think anyone would actually build one of these things. I'll use your pain as motivation to try to figure out a way to make it easier on everyone. I also had one module that had some dead LEDs...

I believe that would be ideal, just an app that you enter the info and hit UPLOAD. Converting the INO file into a binary is non-trivial though, requiring like the 250MB esp8266 core be downloaded and then also deal with compiling and all that. Making a SPIFFS image could work with mkspiffs and...

Giant smash of the Like button, it looks great! If you have the whole github repository downloaded, just copy the HeaterMeterClient library folder into Documents/Arduino/Libraries, along with the prerequisite libraries (ArduinoJson and ESPAsyncTCP) downloaded separately. Then load...

Yup someone suggested a giant (2" high numbers) 7-segment display a few years ago and I said that it was a fantastic idea, but then found that big LEDs cost like $10 per number and noped right out of it. I still liked the concept of an always-on at-a-glance display so I hoped that if I made the...

Well the code from the first post doesn't have any display code apart from to the serial port, so that would make sense why you don't see any modules doing anything. You need to upload the MeterMonitor demo and not the code from the first post.

If you check the serial log you should see what's happening on startup. It should say $UCID,MeterMonitor,[some date/tiime] onWifiConnect onConnect If it gets an error you'll see "Socket Error XXX" with a number that might tell you something. Usually all I see is -13 which is timeout or...

I've looked but every one I've seen/bought looks absolutely terrible. Usually they are TN-TFT and have a viewing angle of like 5 degrees before they start turning black and inverting. Most are "6 o'clock", which means they're for portrait display mode and they're hard to read if turned...

I can't stop playing with this thing despite the fact that I can't read it at all. Pushed some changes so that the compiled-in wifi information is only used if you hold the right button, so that you don't have to edit the source every time to change it from connecting to "network". That means...

Huh I dunno. I even tried logging out and I still get the download zip option right on the main page. Maybe GitHub was having a moment or something but glad you were able to get it working. Arduino does some really wacky stuff in the way it crams a bunch of files together and then adds code to...
