Some new Heatermeters. These boards, I believe are called "After Dark" on OSH. I like the look of them. Two of these are spoken for, Atm.
Some of us are still making Heatermeters

Those are cool looking boards! Glad to see you're still making them, John. I just began my Heatermeter adventure not too long ago, and it's an awesome piece of equipment.

Yeah, since its a free upgrade from OSH, I get all my boards this way now. Yes, its pretty good. To bad RPI's are hard to get or really expensive to get, even if they are used. I have not bought any since Covid started and will probably wait until the price drops, if it ever does, to buy one. If someone ask me to make one, thats the first question I ask, do they have a Rpi. The rest of the components are fairly easy to get.

Awesome, Im trying to revive my 4.3. I bought a thermoworks and absolutely cant stand it while I am trouble shooting my HM. Glad you are making these to keep it going.

so if I understand the title correctly you are still building new heatermeters, are you selling them?

My HeaterMeter just died on me. Is anyone still selling assembled HeaterMeters? I struggled mightily soldering my first one and don't really want to do that again.
What sort of failure?

The heater meter board doesn't seem to power on at all. No LEDs and nothing on the display

So, I'm not sure what was going on but I just got it to work again. Even unplugged it and plugged back in a few times and it seems to be working every time.

I'm interested in buying another set of Heatermeter boards - 4.3 board & display backpack. Is anyone selling assembled boards?
I can get you a 4.3. You want the bare PCBs or fully built? PM me.

I occasionally still use my heatermeter, but have recently gone to the dark side and now use a pellet grill.
I found another project called PiFire, which is based on the heatermeter. Despite pellet grills having an extra variable to control (dumping pellets in the firebox). The hardware is actually quite simple as it only requires a few relays to control the fan, igniter, and pellet auger. So it's a much easier build.

Still have bare PCBs? I'd like to buy one.
i have what i think is a 4.3. a couple of years ago the LCD display failed. i ordered a replacement display from DigiKey but that didn't solve the problem. i can still operate it from my computer or phone but it's a pain to discover and change the IP address when my router assigns it a new one.
is there a replacement HM board available?
thanks

Just a sanity check, Ken...
Have you verified the contrast potentiometer isn't set incorrectly?
Have you tired testing/replacing any of the other components the LCD depends on? -- 74HC595N or the potentiometer itself
Here is the LCD schematic if you're savvy enough to dig into it: https://heatermeter.com/devel/pcb/hm-4.3/HeaterMeterLCD.Schematic.png
Ryan--thanks for the quick reply!
i was wrong about the model i have--it's 4.2. i found the schematics directory for 4.2 but not one for the LCD (unless the same LCD schematic applies to both versions). is this overall schematic for 4.2 the one to work with?
thanks

Can you set the router to assigning a static IP address?
