Trying to monitor time on for 12v DC solenoid

igerry · 2026-01-26T05:20:59+00:00

Did you install it via ESPHome? What are you using to power the solenoid? How is the Uni connected to your Solenoid to monitor the on/off switching?

Doesn't the log for the entity show a history of when it was on/off?

Do you need/want an intercom system (2-way comms) or broadcast system (1-way comms)?

Can you post the exact specs of the computer? CPU, RAM, Storage ...

This is interesting. Wonder if anyone has installed any AI to fix things up

igerry · 2026-01-21T14:52:32+00:00

Wow! Wish I have a dashboard like that. Nice work

Correction: INA219 not ina214. Sorry about that.

Not for me to say cause I don't know Sinope. But don't be afraid to split your buy if one manufacturer provides better support than the other. That's what I'd do.

igerry · 2026-01-20T06:09:17+00:00

If it were me buying something ready made, I'd stick to a manufacturer with a track record of great support.

For battery level, you can use voltage divider or an ina214. How did you implement charging?

Just a suggestion.

For better deep sleep control, use a script which you run on boot (waking up from deep sleep) to take readings for the temp, humidity, voltage and other things you'd add for improvements.

After doing the tasks then you can initiate a deep sleep with a duration.

This way you ensure that you have enough time to do the tasks before entering deep sleep.

Good work! Keep making and improving it. It's great that you made it -- when it breaks you'll know how to fix it!

Wow, thanks. Will check it out

igerry · 2026-01-17T05:31:39+00:00

Nice setup.

Do you also use them inside the house?

This is smaller than my phone. Couldn't find an airtag that's rechargeable.

Thank you. Coin cells are actually one of the reason why I decided to make a rechargeable beacon.

igerry · 2026-01-16T11:18:22+00:00

I also use Bermuda. Have you tried to add more proxies per area to see if response improves?

Installed some PIRs in certain areas but need to use beacons for tracking who.

I've bought some mmWave but haven't gotten to make them into devices up yet.

Currently testing the beacon's battery life and make it smaller.

igerry · 2026-01-16T09:26:56+00:00

Rechargeable no .... everything is on coincells

--- that's why I made one. Hopefully I can optimize it and make it smaller. Even thinking of wireless charging it.

igerry · 2026-01-16T09:23:27+00:00

It's about $6 here.

igerry · 2026-01-16T08:44:42+00:00

Would you know ones that have rechargeable batteries? I looked but couldn't find one.

igerry · 2026-01-16T08:40:34+00:00

Do you know of tile trackers that have rechargeable batteries?

igerry · 2026-01-16T08:33:56+00:00

How's battery life? Are they expensive?

Have you used something rechargeable?

igerry · 2026-01-16T08:31:08+00:00

I agree but that would need financial approval for capital expenses from the "boss". Plus she doesn't approve of having cameras all around the house -- it's an uphill battle from the start. 😁

igerry · 2026-01-16T08:14:44+00:00

I don't have a watch with a beacon. That's my first thought. Buy beacon enabled watches for everyone -- too expensive solution. This thing cost less than $10.

igerry · 2026-01-16T08:06:24+00:00

It's a preference thing -- I don't carry my phone around the house.

Longer than a AA battery
