New 4.0. No IP address.

My new heatermeter started up fine. Probes work. Thermister works. Button works and can scroll through screens. Never saw ip address come up. Have tried wifi and lan cable (tried direct to laptop and then direct to router) but cannot see the heatermeter on my laptop. Opened up the case and can see led lit on the rPI so assuming it has power. Using the 8gb card that came with my rPI. So, can't get to config page or use wifi. What am I doing wrong? Terry
 
Sounds like it's not getting a DHCP address. Can you give your laptop an address in the 192.168.200.x range and see if you can reach the HeaterMeter at the default address of 192.168.200.1

Thanks. I have tried that with wireless and with lan cable connected to router and then to my computer. It just times out when I type in 192.168.200.1 .

Am also curious that when I connect the heatermeter direct to my laptop with a lan cable (that I know is good), it doesn't show up on my computer?
 
If you don't give your computer an IP on the same 192.168.200.0/24 network, you won't be able to connect to 192.168.200.1

You need to change the IP of your computer to 192.168.200.10 and then you should be able to reach 192.168.200.1, assuming the IP stack on the HM is functioning properly.

You won't be able to connect to it wirelessly until you first connect to it via the wired connection and go through the wireless configuration screens.

That sounds promising. Thanks very much. Need to figure out how to change my computer's ip address. Using a Mac connected to fios router. Can borrow wife's pc if necessary. if i connect heatermeter and my mac to the fios router with ethernet cables would that help?

On a mac, to set a manual IP do the following.

Go to system preferences, click on network, click on your wired (not wireless!) network device on the left hand side.

In the right side, change Configure IPv4 from "Using DHCP" to "Manually" and put in the following information

IP Address: 192.168.200.10
Subnet Mask: 255.255.255.0
Router: (leave whatever is in here, it doesn't matter)

Click on apply.

Now connect an ethernet cable between the heatermeter and the mac and you should be able to get to 192.168.200.1
 
Progress? Was able to get it up and going. Thank you!

Did a config, adjusted for my thermister and two maverick probes and got wireless going. All was well. After 30 minutes or so I got curious so tried to pop in a third probe I had laying around. Bad temp shown so took it out, but by coincidence or not, about that time I lost connectivity to wifi. Now it doesn't seem to talk to wifi or ethernet again? Baffled and frustrated. Settings I made while up and going seem to have stayed, so I guess that is good. I have it out of its 3d printed home. Am able to see the rPI LED's on. SD card seems well inserted. Connection between rPI and 4.0 board seems fully inserted.
 
For some reason the last HM release doesn't always connect to the wifi the first time I power it up, if I power cycle the HM the second time it usually connects. IDK WHY, but it has happened often enough for me to notice the pattern. This had never happened to me prior to installing the latest update. So, I usually watch the wifi dongle for a little bit after I power up, if I don't see it start to flash I power cycle the HM, the second time WIFI always starts to flash and connects. Not sure if this could be your issue, but I thought I would report the behavior in case.
If this is not the case then go back to your wired LAN connection and connect that way and look into what settings have been saved in the wifi section.
 
No joy. Thanks for the additional info though. Now I can't seem to connect with ethernet cable either, just like before. On the Mac's network page I get "Either the cable for Ethernet is not plugged in or the device at the other end is not responding." so frustrated now I am forgetting what we did last time. Both computers plugged to router or HM plugged directly to Macbook Pro? would i need a crosslink cable to do that?

i have tried the IP assigned by my router during config and the original 200.1.
 
all you need is one of the two ports to be autosensing and you shouldnt need a crossover cable. TBHWY I am not sure if the rPi lan port is autosensing or not, but I am able to plug my (windows) laptop into the rPi with a straight cable and it will connect. If neither of the ports are autosensing then you would need a crossover cable, but autosensing is pretty common these days... Im not 100% sure if reset will reset the wifi and lan settings, but you might try using the HM menu (last item) and do a reset then reboot and then try to connect like you did at first....
 
The RaspberryPi's ethernet port is Auto-MDIX, so you can hook it up to anything without a crossover cable.

Perhaps booting it with an HDMI cable attached to a TV / Monitor might shed some more light onto the problems your're having.

I am having this same problem. I had everything working great with the wireless, then I powered down, and now I cannot get the wireless to connect. Is there an earlier version of the software that does not have this issue?

Okay. I am booting while hooked up to a TV and can see the bootup. What should I look for? I have already read not to worry about unchecked fs and IRQ 6. Is there a way to stop the scrolling? Do I need to buy a keyboard?

Still no luck. Have added a new power supply (1.5A), a different SD card (even though the first one came with my rPI), and have confirmed that the Ethernet cable is working by plugging laptop direct to router. Cannot get any connectivity from wireless or Ethernet cable. MacBook accepts the IP address I entered but says the cable is disconnected, even though it is going straight to the rPI.
 
I've never hooked them up directly to each other before, I've always used some sort of switch/router/hub so I can't comment on that.

If you've got the Pi hooked to a monitor and plug in a USB keyboard you can hit enter after it boots then type `ifconfig` and see if it has "inet addr" listings for eth0 and wlan0. eth0 should be 192.168.200.1. If it is, type `route -n` and make sure you don't have two entries for 192.168.200.0.
 
Bryan, I wish I could get that far. With HDMI to my tv, I can watch it boot, but the usb keyboard is unresponsive. USB is not working. After 30 or so lines, it keeps repeating "indeed it is in host mode hprt0 = 00021501. The red power led on the rPI is lit. The green LED flickers a little. The other two leds stay dark.

Unplugged everything from the rPI except a power cable and the sd card. Same result.

Am thinking about trying the oven bake approach to the rPI. I assume the rPI is not returnable anyway since I cut off the one jack.
 
Try using a different distro on your SD card like raspbmc or something and see if that works. It's quite possible that your SD card is being stubborn, which looks to be a somewhat common experience on the rPi
 
I've never seen that error but some quick googling says that the USB on the Pi is all mussed up for some reason.

You can also try re-imaging the firmware and then preventing Configuration Restore as outlined in the wiki How do I prevent config restoration?. When booting after doing that, have it hooked to the TV and watch the boot process and see if it gets the same error or reboots twice and then gets the same error.
 
This would be the second time in the past week I have read about a bad rPi. And I am starting to think my situation where the wifi doesn't always connect might be tied to the rPi USB as well. Recently my wifi quit working altogether and swapping the wifi dongle into the other USB port resolved the issue. Though my rPi and wifi dongle have been through the mill, the plastic tip on the wifi is actually broken so my flaky connection could be related to that. I just received a new edimax wifi dongle today, so we will see... eventually, after I get this pile of snow off my driveway.... We're just not getting a break from the winter weather here in the midwest this year.....
 
In the fall, I was having all sorts of random wifi problems on my HM but it's been fine for the last few months. I think it has more to do with the wifi adapter being so small and not being able to overcome other wifi/RF in the area. Doesn't matter how awesome your access point or router is, if the client can receive the signals but not send them back, the battle is lost!
