New Heatmeter


 
Yep, you can connect an ethernet cable from the raspi to your router. After you power it on, you should see the IP displayed on the LCD display, or you can refresh http://heatermeter.com/devices every minute to see if your HM shows up.

With regards to the servo, you'll want to test for 5V at the output pin on the HM board ( near the bottom left of the image below )

Like I said yesterday, you should check the servo wires for continuity to the CAT5 jack on the HM board

Brown to Ground
Red to +5
Orange to SERVO

If those are good then you can look at Q5, which is the servo booster transistor. It should be a BS170, so verify that is what it says on the transistor to be sure its the right part, and that it is installed in the proper orientation. That is really the only part between the ATMega and the servo (besides the CAT5 jack and cable)

Thank you I will be checking that out also. Appreciate all the info so far to help me get these issues resolved.
 
Q5 being the only component between the ATMega and the SERVO pin on the CAT5 jack, if you find your servo to have proper continuity on all 3 wires to the CAT5 jack and you have +5v on the CAT5 +5v pin, then Q5 is where you should look.

Q5 is right above the rPi header, it is the servo booster transistor. You can see it has two green legs and an orange leg in the diagram posted above. If you short the two green legs together that will bypass the servo booster and eliminate the transistor, if your servo moves with those legs shorted then replace Q5. It is not a "required" part, the servo will move without Q5, it is there so the HM can drive the servo with more authority.
 
So I'm sorta doing a happy dance. Found that I had some wires on the Cat5
Fan housing connector wrong. Put them in the correct places and now the servo moves, but it moves in the opposite direction that it should. In the menu is that what the invert check box will do? Change the direction of the servo? I also hope this may resolve the Wi-fi issue somehow but I'll have to wait until I get home to check it out.
 
Yes, the invert setting will make the servo move in the opposite direction. IDK what wires you had crossed up, but hopefully setting them right will clear up whatever had been freaking out your wifi connection. Sounds like you are making progress now....
 
So one step forward, two steps back as the saying goes. Servo was working and going in the correct direction when I checked the invert box. But was is the key word, I guess I was trying to dial it in to much and the servo had a meltdown. Order one and hopefully it will be here by Saturday. On to the other issue, when on Wi-fi it still brings my Internet to its knees, didn't get to test it wired to the router with a Cat5 cable because of the servos demise. So I went ahead and ordered another Wi-fi adapter when I ordered the servo.
 
The servo's are controlled by feedback from a internal potentiometer so the limits (SPD numbers) are different for each servo. In general 700-2100 is a safe range of operation but you want to make sure that you do not use upper or lower SPD numbers that attempt to push the servo beyond it's range of motion, if you do that they will sit there and rattle and hum and eventually burn out or seize up. You also want to be careful about rotating the servo by hand, particularly at the end of it's range of motion, sometimes you can make the gears bind up if you rotate them too forcefully by hand or attempt to twist them beyond their limits.
When calibrating your servo it is always a good idea to have the HM move the servo to its limit and quickly unplug the servo, then gently rotate it a bit more in that direction to be sure you aren't attempting to send it beyond its limit(s).
 
So time for another update installed a new servo and all is good on that front. Using a different SD card and wired to my router all is fine and at this point no noticeable issues with the internet. But the problem now is I cannot get it to connect through the wireless, I've tried both wireless USB devices that I have on hand. The original one and the one I just purchased.

So this is my screenshot of my first cook this weekend. Had to have it hooked up wired during the cook, I still have no wi-fi connection. Same issues as above persist.
 
Can you connect in AP mode? Do a fresh install of the firmware from the image file (on your SD), let it install and boot until you get the address 192.168.201.1 showing after HM boot. Then go to your wireless connections on your computer and see if the heaterrmeter network is available. Connect to that network. Go to a web browser and enter 192.168.201.1 and if AP mode is working, it should take you to the HM page. This may indicate if you have an issue with your wifi dongle itself.
 
Wow didn't realize that I hadn't been on here in so long. So let me update my progress on my HM, I feel I had my first successful Wi-Fi cook last night. I think my primary issues before with Wi-Fi went away when I replaced my wireless cable modem. Here's what the cook looked like:

Only thing I need to figure out now is the port forwarding, I not able to get the PitDroid to work outside my home network.
