| '''TODO''' problem with 74(mb) and 75(peri), furthest away devices. Constant wrong low readings followed by correct readings try new power supply first
| |
|
| |
| Supply for the six 8266's and 7 relays blew today, flashing on and off. Replaced with same kind. It lasted since 11/19, 2 1/2 years, when that disastrous upgrade happened while I was sick from derm drug.
| |
|
| |
| max power esp8266 170ma * 7 = 1672ma
| |
| power for 8 relays
| |
|
| |
| The "L" in SRC-05-SL-C means 0.36 Watts. Since Watts is Volts times Amps we can divide by Volts to get Amps:
| |
|
| |
| 0.36 / 5 = 0.072 = 72 mA per coil. * 8 = 575 mA
| |
|
| |
| total power needed: 1672ma + 575ma =2247ma NOT 700ma

| The design embedded in the wooden plates for all but the living room uses a tiny pcb soldered right to the esp8266 with the sensor haging out so as not to be overheated by the chip. This KICAD esp82single design can use espboth/secstidif with a CONF_CYURD074hvacMB.cpp like configuration. All other fixes should use this version. Flaky devices are the master bedroom and peri's study. For the master bedroom, re'flashing brought it back to life. Had trouble flashing. Turns out I tried 3 bad usb cables in a row so I thought it was windows 11. You can check for a working connection in DeviceManager. view/show_hidden_devices. CH340 is the driver for esp and I plugged it into CYURD001 and its listing under PORTS changed from greyed out to dark when a good cable/connection was in play.
