I sincerely hope that, when the Tories finally decide who gets the poisoned chalice of leading the party, a general election is called.

You may also be able to use a car/auto parking sensor (scrap yard) but may also need the controller board.
There are articles online, not sure if they may relate to use with a Pi

Butyou already have another device in the receiver/transmitter at teh other end.
Why not substitute that with one of the Arduino style RF boards, ESP, NRF, panStamp etc?

panStamps aren't the cheapest but are very reliable and very low power. I'm getting 4 months or so with a single AA cell on my energy sensors involving many input pulses. Temp and humidity sensors much longer than that. panStamps can be used without a battery board, powered by two AA cells but the c...

Self-heating has nothing to do with how close to your Pi the DS1820 may be placed but , as edo1 infers, is to do with heating of the DS1820 internally. As said earlier I know nothing of bit-banging DS1820 but if it uses w1 then that code derives from owfs AIUI though I have no idea which owfs versio...

My recollection is that the DS18B20 calculates the temperature and transmits that value to the Pi. Is there any chance of self-heating in your setup?

Yes but that may block other things. You are using 'daynumber = datetime.now().strftime( '%j')' I'd guess there would be parameters for intervals smaller than a second even if it's just a fractional value of a second. Store that value in a variable and check it as you do for 'if daynumber != datetim...
