I seem to get a lot of interference - how can I reduce this?

Check these 2 circuits.
Instead of switch connect your temp sensor on/off pin. (high/low states)
Transimitter Receiver
D0 - D0 OUT
D1- D2 OUT
D2 - D3 OUT
D3 - D4 OUT
Only if the transmitter is permanently enabled by shorting /TE to ground, causing respective current consumption and blocking concurrent RF devices. According to regulations, more than 10 percent duty cycle isn't permitted.Connect you temp switch on an of the pins (D0 or D1 or D2 or D3 or D4) and the corresponding out pins at the receiver will change with switch state.
Or I can just used a normally closed temp switch and when the switch opens it activates the receiver

Can I use a different value resistor than a 750K
