Really enjoying these cheap Xiaomi temperature sensors and Grafana.

This chart shows the temperature inside and outside an incubator. I also have an S9 ASIC in the same room that runs on a schedule. I figured out how to use the state of the S9 smart plug to show when it's turned on and off.

It's interesting to see how the ambient temperature rises immediately with the S9 running, and how the cycling of the thermostat becomes less frequent and stops entirely when ambient is near the target temperature.

I guarantee there is at least one local brewer near everyone who works really hard to make good beer and desperately wants your business. If not, make your own. It's not that hard.

In theory Zigbee has more range, but in my limited experience it's only slightly more than Bluetooth.

I'm not sure about durability. Both seem to be intended for indoor use only.

They both use a CR2032 and I haven't had them long enough to see a battery die. I'd get some warning with the Bluetooth sensor because it reports battery level.

For precision, the Zigbee has a wider range but less precision: -20 to 50 C at +/- 0.3 C vs the Bluetooth 0 to 60 C at +/- 0.1 C. For humidity the Zigbee is +/- 3% while the Bluetooth is +/- 1%.

There are pros and cons to both, and the best choice depends on your own circumstances and needs. I think the Bluetooth sensor is the better choice when you need higher resolution data or the LCD display. On the other hand it can't measure below freezing.

A Tale of Two Sensors

The yellow line is an Aqara Zigbee sensor with temperature, humidity and pressure. It doesn't update the sensor readings very often. It costs $15 and requires a USB Zigbee adapter for $20-30. Many Zigbee devices also act as repeaters to extend range. [1]

The green line is a Xiaomi Bluetooth sensor with temperature and humidity. It costs $6 and requires a $6 ESP32 to bridge bluetooth to HomeAssistant with the ESPHome firmware. You also get an LCD display, battery level, battery voltage and signal strength. [2]

So for $3 less you gain high time-resolution sensor readings and an LCD screen showing temperature and humidity. You lose pressure, but pressure will be the same everywhere so it's not necessary to have it in every sensor.

The graph comes from Grafana integrated with HomeAssistant. These particular sensors are monitoring an incubator.

I think it will be fine as long as the concentration is not really high.

"Manure and bedding from 60 horses at Oxley Equestrian Facility, Cornell University, Ithaca, NY de-wormed with 114 mg ivermectin paste each, was collected over a 3-day period in 2011 for composting. The presence of ivermectin did not appear to affect the composting process as shown by thermophilic temperatures and proper mass loss. There was a severe drop in ivermectin concentration in the manure/bedding mixture within the first few days of composting indicating exponential decay. "

And with this the final nail goes into the coffins of shit coins like Algorand and Cardano. Softwar by Jason Lowery connected the last dot on BTC Dominance for me.

I feel dumb for not getting there on my own. I have said forever that what backs bitcoin is security. DUH! Once you understand that security is the point, security of money, security of data, there is no difference. Data is money and money is data. Matter is energy and energy is matter. (hold up, some of y'all ain't ready for that yet 😀 )

Anyway if you look at the entire "crypto" space though a lens of security, #bitcoin is the only thing left standing. When you want security, do you want okay security, decent security, half ass security?

No you want the best.

The only reason people settle for second best in security is lack of access or the cost. Well security via Bitcoin is open to all and it is CHEAP, because you pay for it only when you secure something one time, then you never pay again unless you transfer ownership of it.

So if you are going to secure a land title, a deed, a car title, a contract, your will, your personal data, corporate data, etc. why would you use any security other than the BEST security you can get.

And nothing man has ever built is more secure than Bitcoin because it imposes a physical cost in the virtual world. When you view it this way, the entire "slow" and scaling problem goes away. They are not flaws in bitcoin they are features.

The slow and hard parts of the blockchain make trying to hack the network so costly that you just can't afford to attack it. It is like a shied that makes you impossible to harm but the harder an enemy hits you the more they hurt themselves.

POS networks can't do this, any POW network that isn't bitcoin simply isn't as secure. There is no place for 2nd place. The highest hash rate other than BTC is LTC. LTC has a hash rate of 770 TH/s, BTC's hash rate is 345 EH/s.

The magnitude is such that to quote Ricky Bobbie, "If you're not first you're last".

Ordinals are like weeds, showing us the fertile ground of unused block space. Now we have to figure out what to plant in it.
