Latest Software: LinkMeter v13 and firmware


 
Can I install this release on 4.0 hardware?
Thanks

Tragedy + Time = Comedy they say and if there was anything awful about LinkMeter v12, we'd all be laughing about it now. The current stable version of HeaterMeter software is now version 13, over a year from the last release. The release zip file includes the OpenWrt host operating system, LinkMeter daemon, and HeaterMeter AVR firmware.

HeaterMeter AVR Firmware Update 20160204
  • Control probe is no longer PIT, now uses first non-disabled probe. Note that a probe reading "Off" isn't disabled, only probes with their type set to DISABLED count as disabled. All the temperatures on the web homepage will still be in the same places they were, regardless of which probe is controlling the pit.
  • Replace fan "on at max only" with "fan on above" to allow finer control of when the fan is used.
  • Servo can be set to max open at any PID percentage, not just 1% (Full open/close option removed).
  • Servo now moves a constant speed to its destination and holds for 2 seconds before de-energizing. Small moves are held off for up to 10 seconds from any previous move to reduce servo chatter.
  • "Reset Configuration" from the HeaterMeter now resets the OpenWrt configuration back to default as well.
  • Option for filtering out 50Hz/60Hz line noise on the probes for more stable readings.
  • Added some small menu acceleration to the HeaterMeter device menu. Holding the button down will get you the first 4 ticks at normal speed, then 4 double speed, and the rest quad speed. e.g. the SetPoint is 5 degrees, 5, 5, 5, then 10 degrees, 10, 10, 10, then 20 degrees, 20, 20, 20...
  • PID B has been removed from both the UI and the firmware. The PID I term should provide the same functionality
  • Prevent low current fans from oscillating between very low and very high voltage.
  • Stored up PID sum doesn't reset when changing the I coefficient any more unless you change the PID to 0.
    [*] The integral sum, PIDI, could go negative when decreasing the setpoint, which would extend undershoot recovery times. Fixed.


OpenWrt Firmware LinkMeter v13
  • Updated Pi firmware to support Raspberry Pi B+/A+/Zero.
  • Ramp (and hold) mode for slowly shutting down the grill at the end of a cook.
  • Added support for loading wifi settings from config.txt
  • Fix alarm scripts page deleting the second script every time you try to add more than one.
  • Last high and low Pit peaks information added to tooltip on home page.
  • Pushbullet and Pushover notifications for alarms.
  • Proper https support in curl utilities if you need that for your scripts.
  • Updated Steinhart coefficients for Maverick ET-732 and Thermoworks TX-1001 based on 1000+ point thermocouple correlation 80F to 400F.
  • Prevent the browser from getting bogged down the more times you updated configuration without a page reload occurring
  • Register the hostname from the system configuration if one is not specified in the dhcp client configuration
  • Added luci-app-commands package for running shell commands without having to ssh in
  • Fixed not being able to dismiss graph "tooltip" popup on touch devices.

Wifi Settings via config.txt
As mentioned above, there's now an easy way to set your wifi configuration before you even boot the HeaterMeter for the first time. Just edit the config.txt file in the DOS/FAT partition (the one you see when you insert the SD card into a windows PC). At the bottom of that file there's now a Wifi configuration section.
Code: 
##
## wifi configuration
##
# SSID (network name)
#wifi_ssid=heatermeter
# Password for encryption
#wifi_password=password
# Encryption mode psk2 (WPA2-PSK default), psk, wep, none
#wifi_encryption=psk2
# Mode ap (Access Point) or sta (Client mode, default). Must be lowercase!
#wifi_mode=ap
# wifi channel, only used in AP mode
#wifi_channel=6

Regular wifi client mode with WPA2 security:
Just uncomment out (remove the # at the beginning of the line) for the wifi_ssid and wifi_password.

The configuration takes place at the end of boot, after the network has already been initialized, so you'll see it pop up in the original mode first, then switch to the desired mode. This is because it needs to take place after the configuration restore has occurred (if it is going to). Once the wifi settings are loaded, it will automatically comment out all the wifi values in config.txt so it won't reset them again. Note: If your wifi SSID or password contains quotes (single ' or double ") then you're going to experience a nightmare trying to get this to work. E.g. your SSID is "Bryan's Wifi" = mal tiempo.

Upgrading
To upgrade from a HeaterMeter with internet access, just go to System -> Backup/Flash Firmware and paste the link to the v13 .gz release into the "Image URL" box. The AVR firmware should update automatically to 20160203B.

This update can also be written to the SD card directly and for fresh installations, use Win32DiskImager (windows) following the instructions in the wiki. HeaterMeter 4.x Software.

Glad Bryan confirmed backward compatibility, I was pretty sure but not 100%. One thing on v4.0, it doesnt have the feedback circuit on the blower. So you can't use Voltage mode, you have to use Pulse mode for the blower.
 
Little confused on how to correct an issue I'm having since upgrading to this V. of software. Everything is working fine except when I power it up it always gets a different Wi-Fi address than the previous time. What have I done wrong that I can't get it to use a static IP address.
 
After talking it over with some knowledgeable friends at work. I think I might have figured out my problem. I'm hoping to look at it this weekend. I'm going to assign the IP that comes up in my router to be static to that particular Mac id.
 
You can assign a static IP inside the HM in the network section, or you can assign an IP to the device in most wifi routers as well. Either will work to keep your IP address the same.
