no, leaf it out, don't coriander business. Or if you must, go gingerly. That's my sage advice, anyway.

Why are you only selling Herbs, and no Johns, Georges or Joes?

Forget the beer. I hope Griff's doctor also can mix you a mint julep[^], Georgia style.

I'm looking for hardware platforms which should be very low power (they should last several months on AA batteries, max 2-3 each), possibly low cost with Bluettoth or some other radio capabilities, available temperature sensors (not necessarily on chip) and not too expensive.
I'm trying to build my smart thermostat and these objects would be the temperature sensors in the various rooms. The main controller will probably be a Raspberry or an Arduino, no limitations on power supply since it will be wired.
Do you have any suggestion or ideas? Each remote sensor should not cost more that 20-30€ including the actual temperature sensor.

I worked with SparkFun ESP8266 IoT board and with the TMP102... It gives you a WiFi connected, fully programmable thermostat (and more)...
If you are using a rechargeable battery it may help, but thermostat (it runs all the time, so no sleeping) can be energy consuming...
Probably the best way is to make battery replaceable (using charged spare), by adding a flat Lithium-Ion and a cell (like CR2032) to backup...

Batteries will be replaceable. The thermostat will be powered by line, only the satellites will be powered by batteries. Also, the satellites need to cycle only every 5 minutes tops, so no big problem.

I would reccommend my old CDP1802 microprocessor. It does not get any lower power than that, if you can live without power wasters like LEDs or displays. Still, it's now becoming hard to get after a long lifetime and you are probably better off with a modern microcontroller.
I think a PIC microcontroller might do it. They cost five bucks or even less and need prctically no additional parts if you pick the right one out of a vast sortiment. It should have a UART to communicate with the Pi, and perhaps A/D converters for the temperature sensor. Also, it should have a power-on reset built in (not all have that), an internal oscillator, and it should be a low power CMOS version. Hint: The operating power of CMOS devices is dependent on the clock frequency, so set the internal oscillator to the lowest value that still cuts the cake for you.

Good. I will look if I can find some component that goes from UART to Bluetooth or similar. Thanks!

Did a quick search and found this: Bluetooth HC-06 Module Interfacing with PIC Microcontroller[^] You might use a similar module and the PIC's USART.
And this, what the temerature sensor is concerned, which is indeed hooked up to an analog input for the D/A converter: Temperature Sensor using PIC microcontroller[^]
If this PIC16F877A has a USART, you can hook it up as shown, forget about the display and hook up the the Bluetooth module to the USART. Done with the hardware, let the software part begin!

Man, you basically solved the problem! Thanks!

Microchip do a massive range of different micro controllers, all at different price points.
If your in the UK, I usually use these guys to supply my PIC's:
V&U Electronic components LTD
You can also use the Microchip search/match tool to find the perfect PIC you need for your project

This is definitely the way I would do it, but I'd go with a Bluetooth Low Energy version of the HC-06. There are variants, but HM-10 is a good starting search term for a lower power drop-in hardware replacement for an HC-06. Start with the HC-06, get familiar with the hardware/software, then switch to using the BLE version and figure out the differences in usage.
The bluetooth radio is going to be your biggest power draw, hands down, so you should definitely consider the BLE version.
PIC is a really good idea, you can get nA sleep currents out of them if you pick the right chip and know what you're doing (read the datasheets).
