I am having this same issue looked at all the recommendations here, any other thoughts. No Communication HeaterMeter serial communication can not be established. Configuration requires bidirectional serial operation. Possible causes of failure: No HeaterMeter board attached No HeaterMeter...

I built my first one with no problems, worked great until I let someone borrow it. I built one of the 4.3 and can't seem to get it to work. How much are you charging to build them? I only need the internal parts, I have the case for it, using the Raspberry PI B+

Can you still get the part to build these, mine died. Looking a new one. Any updates looks like its been a while since any posts.

I have tried that.

I am frustrated to the point of no return, I have assembled two 4.3 heater meters, and neither are working. I am not sure on how to trouble shoot it. I built one of the very first modles with not problems, but this one has got the best of me. when I start them up I get nothing but black...

Anyone have any idea what I need to trouble shoot this projecct. I ordered a new board and parts yesterday, maybe this one will go together without any problems.

I download the snapshot and that didn't do anything, started checking voltages, no voltage on the middle leg of the P-MOSFET, no power at BFB on the ATmega chip or along that whole line. Not sure where to go from here. I checked all the solder connections, they looked good, checked to make...

Finally got it all together, downloaded the image flashed the card. plug it in and the green and yellow LEDs come on but nothing else happens, been sitting now for about 15 minutes. 4.3 built with the PI Zero W, any suggestions on where to start trouble shooting. I have adjusted the...

Figured it out, thanks. Now cant seem to gert it to boot up.

Is there somewhere that explains how to attach the PI Zero to the heatermeter board, I have looked and cant find it anywhere.

Which is the best Raspberry to use when building version 4.3

That is the same display I used, the case I got from Matt fit perfect, The only change I had to make was to change the pins to a 90 degree set of pins. The display works good in the sunlight I have not had any problems since I finally got it set up and running.

I used a piece of 3/4 copper pipe hammered square on the end and attached to a 3/4 pipe close screwed into my UDS. This setup works pretty good for me. [/IMG]

I was also wondering about the bluetooth connection also, and was searching the web for bluetooth with the Raspberry and found this site (http://blog.miguelgrinberg.com/post/a-cheap-bluetooth-serial-port-for-your-raspberry-pi). This information is a little above my knowledge base when it comes...

I am doing my first cook with the Heatermeter, i have noticed that theambient temp has continued to rise the whole time, it is currently around 106 degrees, the outside temp is in the low 80's. Should I be concerned about this.

I had some of the same problems, I changed power supply and everything is working fine. Make sure your power suply has atleast 1amp output.

I now have one, still trying to get wifi issues worked out. Probably be building one more for my dad.

I had some of the same problems you have, see if you can log into RPI through the ethernet cable and see if it recognizes the HM board is connected. Im really not 100% sure what fixed mine but this is one the things Bryan reccommended and mine started working afterwards. "If you can get...

Not sure why or how, but it is now working. thanks for your help, im sure I will have more questions as I begin to learn how to maniplate it.
