- toomuchtodo 6y agoWill this work in the US with a US SIM card?
- yetihehe 6y agoWe didn't test it yet, but probably not. In UK (where the author of article resides) yes. Sim card is soldered in.
- toomuchtodo 6y agoPlease consider the US market for future iterations (and a SIM socket if it’s a reasonable price on the BOM). I believe Twilio even offers a global SIM with reasonable IoT data rate pricing.
- yetihehe 6y agoIt was more about space, it's small module inserted into that big detector. We would probably just make different module for US. Worldwide module is in planning stage after nb-iot takes off more widely.
- the_only_law 6y agoI’ve read about all sorts of alarms (I don’t think smoke, but fire and other emergency alarms) running on things like ISDN before the term IoT ever existed
- yetihehe 6y agoAnd I've worked on telemetry devices which had modem and could phone alarms and data to control room over landlines before there was any ISDN available. This was for city heating control. My company was upgrading this to mobile connectivity. Whole system earned it's worth after one pipe break, because operator could select area on map, turn off all flow to different devices with several clicks and they didn't have to use complicated freezing devices to fix pipe.
- edent 6y agoThat looks neat - any UK stockists? Looks to be about the same price as Nest once shipping is included.
- yetihehe 6y agoNo, currently only sent from poland.
