A T&P valve discharges for 2 reasons Temperature & Pressure.
Most in a residential application will discharge at 150 Psi. (which it is) or, at 210 Degrees F.
You need to take some tenperature & pressure measurements to determine the cause, Most of the time we see a discharge due to thermal expansion. Usually a discharge of about a coffee cup or 2. (Since its happened 2 nights in a row, Im thinking the same thing)
Do you have a pressure reducing valve installed on your house?
Go you have an expansion tank installed on your water heater?

No and No. I was quite surprised to find out the city does not require a PRV at the service entrance.
Ive never needed a ET in the past. Pressure has been a constant 55psi since day one. We have a city jockey pump located about 2500 feet from the house.
Maybe both WH stats are baked? Doesn't seem likely though.
