Hey guys. So my router assigned a new IP address to reef-pi last night thinks to a power outage. I lnow, I know. DHCP etc etc.
I've been searching for a tutorial to follow on how to set up a Static IP so I don't go through this again. Does anyone know a reliable one for me to follow?
Edit - my reef-pi is on wifi if that makes a difference.

On your router you can, most likely, set a DHCP reservation for the current ip adress that is assigned to your pi. See manual of your router how to get it aranged.

This is related to either incompatible name of equipment/some other elements name in reef-pi (with space ) or too many data point being submitted to reef-pi. Adafruit is free account only allow 6 feedsJust the latest version of Raspian. For errors I’m getting the occasional temp probe error that everyone else is getting, then I keep getting a bunch from Adafruit IO:

reef-pi legs failed login attempt. It’s logged in stdout and available via standard journalctl -u reef-pi.service . Check how fail2ban integrates with journalctl. Keep me posted

Can you run ‘ps aux’ and share the output. There must be something that’s eating your cpu, reef-pi alone should not be that intensive

Your router is the one where you have to make dhcp reservation. I use google WiFi which allows this via their app.

If you set the pi to use predictable network interface names, you can setup static IP addresses in /etc/dhcpdc.conf
mine looks like this:
# Example static IP configuration:
interface wlan0
static ip_address=192.168.0.10/24
static routers=192.168.0.1
static domain_name_servers=192.168.0.1 8.8.8.8

As @GaryE mentioned you can do this in the dhcpdc.conf file. Here's a little write up on it.

Yeah linux cpu monitor works a lot different from winblows stuff, it provides a number based on core utilization, if you have a multi core machine it can and will read over 100% based on load. I have an 8 core machine and if I am doing heavy cpu work my cpu percentage can read 440%, basically I am using 4 cores and and 40% of the fifth core. Right now it appears that you are using one and half cores and reaf-pi should only be using .2 or .3 (20-30%) of a single core.
From the console prompt you can also run top and it will show which processes are using the most resources, if you can capture that output and display here that will show us what is consuming the resources.

Hey @Des Westcott if you can give me the model of your router I will look it up and see if you can do DHCP reservations, willing to help just let me know.

Nice work, so where is the best place to hopefully get authentic probes from? Would be nice to know a good resource to hopefully get legit probes.

There is quite abit to it, however, I found the interface fairly intuitive and had my graphs built fairly quickly.
I suggest looking at other already built graphs and going from there.
Here is the JSON model for my QT setup.
This pi only monitors / controls the temp in the tank.
The graphs are pretty simple, one Temp graph, one that shows the current state of the heater and one that shows the state of the heater over time.

Ummmm. Bru, you're underestimating just how "dumb" I am with this.
That literally looks like the Matrix scrolling down my screen . ;Hilarious

How to tell original from fake DS18B20 temperature sensors. - cpetrich/counterfeit_DS18B20
"Solution to the 85 °C-Problem
There is a simple, undocumented, way to discriminate between the power-up 85 °C-reading and a genuie temperature reading of 85 °C in DS18B20 of Family A [5]: <byte 6> of the scratchpad register. If it is 0x0c, then the 85 °C-reading is a power-up reading, otherwise it is a true temperature measurement."
This is the only thing that bugs me with the temp probes. Ocassionally ill get an 85c and it will alert me that the tank is running hot. Is there anyway to stop this 85c registering?

Well if i understood that link correctly then it is doubtfoul whether pretty much anyone at all here even has family A sensors so i don't know how helpful that byte is going to be, especially for a standard solution

Is it possible to setup the ATO section of reef-pi to require two (or more) float switches to be triggered (reading low water) level before turning on a pump? Can this be done in a macro possibly? Or is wiring them in series the only way?
