We are really lucky, because my school is in a privileged area.
'Devices' are reasonably common - but usually 1 tablet per family, or 1 laptop for a parent trying to work from home + all their children, or a couple of phones across the family.
We set up 'non live' online learning, because it was really clear to us that the times pupils were submitting work was at the weekends, after their parents' working hours, very early in the morning, only for 'their' hour on the family computer etc.
We supplemented it with printed material, or printable material, putting up the resources every Friday so parents hit the website every weekend to print off a week's supply of worksheets if they could.
We accepted work in all sorts of forms - written and photographed, typed, within online programmes, recorded as speech...
We lent out every school-owned laptop.
We had a large proportion of the over half the school who had keyworker parents in school, all with adults prepared to 'teach' and allocated time on in-school IT equipment to get their work done.
Every teacher, after half term, balanced in-school teaching for retuyrned groups + keyworker groups with online learning for everyone else, including video contact with our own classes every week.
We are still berated by some on here because we 'didn't do proper live online teaching'.
