We found technology very helpful when my mum needed support to allow her to live independently in the early stages of Alzheimer’s - I know your mum does not have dementia but some of our aids might be helpful for you.
We installed broadband at her house so that we could have Ring cameras, both the doorbell type and also two way security cameras around the house. This allowed us to monitor people coming to the door to try to scam money from mum, elderly people can be very trusting and fall for door step cons like “ Could you let me have the train fare for me to get my wife’s body out of the morgue” Yes, that person called round every few weeks to con money! The security cameras meant that we could check how long mum was out shopping, if she had not got home within a short time, we would have been able to search for her in case she’d forgotten her address. I could also talk to her through them so helped remind her where to find her key when she forgot where she had put it.
We had to buy a call blocker to intercept scammers on the phone as well, the system provided by her phone company was too complicated for mum to use as it involved pressing a button to reject or block calls. We bought a separate unit which plugged into the phone line. You’d be shocked at how many Sky insurance policies mum had - she did not have Sky!!
We had two indoor cameras as well to give us peace of mind that she had got downstairs safely each morning and had not had a fall.
We installed a key safe outside in case she lost her key or if someone needed to gain access to help her.
Hive heating system was useful when mum forgot how to control the central heating and fiddled with the controls, turning it off or to the wrong times.
Another thing we did which might not be appropriate for your mum was to scratch off the cvc number from the back of her bank card so that it could not be used to buy things over the phone - yes, probably illegal but necessary for us.
Does someone have Power of Attorney for your Mum? If not, I suggest you get it set up asap while your mum has capacity so that you can help her pay bills or make medical decisions.
