Toddler night time potty training

Do any of you lovely parents have advice for how to night time potty train your toddler?
My boy is 2 years and 2 months and has been daytime potty trained for about a year. We did elimination communication from infancy so he is very used to using both potty and toilet and barely ever has accidents. He still uses nappies for sleeping in both day and night time and doesn't wake if he is wet.
Last night we tried wearing no nappy to bed for the first time. I put him on the potty before he went to bed (7.30pm) and then again when I went to bed (9.30pm ish) and then he wet the bed another 3 times in the night! It was a terrible sleep for us but at least he is now feeling when he is wet.
Anyone got any tips and tricks? How did you night train your toddler? Looking forward to a better night sleep for us all!
